The structure of the title compounds 3-bromo-2-(phenyl­sulfan­yl)benzo[b]thiophene (C14H9BrS2; 1), 3-iodo-2-(phenyl­sulfan­yl)benzo[b]thio­phene (C14H9IS2; 2), 3-bromo-2-(phenyl­selan­yl)benzo[b]seleno­phene (C14H9BrSe2; 3), and 3-iodo-2-(phenyl­selan­yl)benzo[b]seleno­phene (C14H9ISe2; 4) were determined by single-crystal X-ray diffraction; all structures presented monoclinic (P21/c) symmetry. The phenyl group is distant from the halogen atom to minimize the steric hindrance repulsion for all structures. Moreover, the structures of 3 and 4 show an almost linear alignment of halogen–selenium–carbon atoms arising from the intra­molecular orbital inter­action between a lone pair of electrons on the halogen atom and the anti­bonding σ*Se–C orbital (nhalogen→σ*Se–C). This inter­action leads to significant differences in the three-dimensional packing of the mol­ecules, which are assembled through π–π and C—H⋯π inter­actions. These data provide a better comprehension of the inter­molecular packing in benzo[b]chalcogenophenes, which is relevant for optoelectronic applications.

Benzo[b]chalcogenophenes derivatives also show relevant biological activities as anti-tumor (Arsenyan et al., 2011[Arsenyan, P., Paegle, E., Belyakov, S., Shestakova, I., Jaschenko, E., Domracheva, I. & Popelis, J.

As part of our continuing work on benzo[b]chalcogenophenes (Luz et al., 2021[Luz, E. Q., Silvério, G. L., Seckler, D., Lima, D. B., Santana, F. S., Barbosa, R. B., Montes D'Oca, C. R. & Rampon, D. S. (2021). Adv. Synth. Catal. 363, 2610-2618.]), we report herein the crystallographic structural comparison of four 3-halo-2-(organochalcogen­yl)benzo[b]chalcogenophene derivatives.

[Scheme 1]

2. Structural commentary

The four organic compounds crystallize in the monoclinic P21/c space group, and all atoms occupy unique positions. Compounds 1 and 2 are isostructural containing an identical 3-halo-2-(phenysulfan­yl)benzo[b]thio­phene unit with bro­mine (1) or iodine (2) at the C3 position of the benzo[b]thio­phene ring (Figs. 1[link] and 2[link]). The isostructural compounds 3 and 4 also contain identical 3-halo-2-(phenyl­selan­yl)benzo[b]seleno­phene units with bromine (3) or iodine (4) at the C3 position of the benzo[b]seleno­phene ring (Figs. 3[link] and 4[link]). The respective benzo[b]chalcogenophene rings and the phenyl­sulfanyl and phenyselanyl groups are planar. As expected, the carbon–selenium bonds in mol­ecules 3 and 4 are longer than the respective carbon–sulfur bonds in mol­ecules 1 and 2.

Conformational changes are observed when we compare mol­ecules 1 and 2 containing sulfur atoms with mol­ecules 3 and 4 containing selenium atoms, as described below. In mol­ecules 1 and 2, the benzo[b]thio­phene ring is twisted away from the plane of phenyl­sulfanyl group showing inter­planar angles of 88.9 (8) and 87.9 (6)°, respectively (Figs. 5[link] and 6[link]). Additionally, for 1 and 2 the S1—C2—S10—C11 torsion angles are −97.56 (14) and 98.17 (15)°, respectively. Mol­ecules 3 and 4 also show the benzo[b]seleno­phene ring twisted away from the plane of the phenyl­selanyl group with inter­planar angles of 80.4 (8) and 79.7 (7)°, respectively (Figs. 7[link] and 8[link]). Conversely, the torsion angles (Se1—C2—Se10—C11) in mol­ecules 3 and 4 are 1.9 (3) and −4.0 (3)°, respectively, quite different than the S1—C2—S10—C11 torsion angles in mol­ecules 1 and 2. It is clear that the coplanarity between the phenyl and benzo[b]chalcogenophene rings is avoided in both pairs of mol­ecules to minimize steric hindrance. This structural arrangement is reinforced by the presence of the halogen atom at the C3 position of the benzo[b]chalcogenophene ring (Figs. 1[link], 2[link], 3[link] and 4[link]). Nevertheless, there is an almost linear alignment between the atoms Br1—Se10—C11 (3) and I1—Se10—C11 (4), which cannot be explained by steric factors alone. For instance, if we consider merely the higher steric hindrance between the phenyl and benzo[b]seleno­phene rings arising from the lower intrinsic C11—Se10–C2 angle directing the conformation of mol­ecules 3 and 4, the almost linear alignment between the atoms Br1—Se10—C11 (3) and I1—Se10—C11 (4) is still not fully understood. We have observed that the inter­atomic distances between the chalcogen and the halogen atoms [S10⋯Br1 (1) = 3.5061 (8) Å, S10⋯I1 (2) = 3.6310 (7) Å, Se10⋯Br (3) = 3.4196 (7) Å, Se10⋯-I (4) = 3.5260 (7) Å] are 0.14, 0.15, 0.33 and 0.35 Å shorter than the sum of the van der Waals radii of the respective two atoms in mol­ecules 1, 2, 3, and 4, respectively (Bondi, 1964[Bondi, A. (1964). J. Phys. Chem. 68, 441-451.]). The shorter inter­atomic distances Se10⋯Br and Se10⋯I and the remarkably almost linear alignment of the atoms in 3 [C11—Se10⋯Br1 = 152.95 (9)°] and in 4 [C11—Se10⋯I1 = 156.52 (1)°] when compared to mol­ecules 1 [C11—S10⋯Br1 = 93.01 (7)°] and 2 [C11—S10⋯I1 = 91.35 (7)°] indicate a stabilizing intra­molecular orbital inter­action (3-center-4-electrons, 3c–4e) between a lone pair of electrons of the halogen atom and the anti­bonding σ*Se–C11 orbital (nhalogen→σ*Se–C11) (Mukherjee, 2010[Mukherjee, A., Zade, S., Singh, H. & Sunoj, R. (2010). Chem. Rev. 110, 4357-4416.]). The lower energy of the anti­bonding σ*Se–C11 orbital makes it a better acceptor when compared to the higher energy anti­bonding σ*S–C11 orbital, therefore making the intra­molecular nhalogen→σ*Se–C11 orbital inter­action in mol­ecules 3 and 4 strong enough to change their mol­ecular conformation.

3. Supra­molecular features

The crystals of organic compounds 1 and 2 are related by an inversion center and assembled through C—H⋯π inter­molecular inter­actions along the b-axis direction (Fig. 9[link]). The weak C—H⋯π inter­actions are between the H5 atom and the centroid formed by atoms C11–C16 of the phenyl­sulfanyl group. The distances and angles comprising these contacts are 2.97 (2) Å, 137.1 (2)° for 1 and 2.93 (3) Å, 138.4 (2)° for 2. The structures 1 and 2 also show π–π stacking inter­actions between adjacent benzo[b]thio­phene rings along the c-axis direction with centroid–centroid distances of 3.7166 (2) and 3.7602 (4) Å for 1 and 2, respectively (Fig. 9[link], for 1). On the other hand, in compounds 3 and 4 C—H⋯π inter­actions are not present. However, π–π stacking inter­actions involving adjacent benzo[b]thio­phene rings are present along the a-axis direction, with centroid–centroid distances of 3.8139 (3) Å and 3.8772 (1) Å, respectively. Furthermore, π–π stacking inter­actions are observed along the b-axis direction between phenyl­sulfanyl groups related by an inversion center, with centroid–centroid distances of 3.6644 (2) and 3.7351 (1) Å for 3 and 4, respectively (Fig. 10[link], for 3).

4. Database survey

Several crystal structures of benzo[b]chalcogenophenes derivatives have been published. To the best of our knowledge, there are no studies about chalcogen atoms attached directly at position 2 of the benzo[b]chalcogenophene ring. With regard to benzo[b]thio­phenes, Xu et al. (2017[Xu, J., Yu, X., Yan, J. & Song, Q. (2017). Org. Lett. 19, 6292-6295.]) described the structure of 3-(aryl­sulfon­yl)benzo[b]thio­phene obtained by single-crystal X-ray diffraction. Additionally, Ramesh et al. (2016[Ramesh, E., Shankar, M., Dana, S. & Sahoo, A. (2016). Org. Chem. Front. 3, 1126-1130.]) reported the structures of 6-fluoro-2,2-(diphen­yl)benzo[b]thio­phene and 6-isopropyl-2,2-(diphen­yl)benzo[b]thio­phene obtained by single-crystal X-ray diffraction studies.

5. Synthesis and crystallization

The structures reported here were obtained by the one-pot synthesis of 3-halo-2-organochalcogenylbenzo[b]chalcogenophenes from 1-(2,2-di­bromo­vin­yl)-2-organochalcogenyl­benz­enes. By this method, a series of 2,3-disubstituted benzo[b]chalcogenophenes were prepared in yields of ca 80% (Luz et al., 2021[Luz, E. Q., Silvério, G. L., Seckler, D., Lima, D. B., Santana, F. S., Barbosa, R. B., Montes D'Oca, C. R. & Rampon, D. S. (2021). Adv. Synth. Catal. 363, 2610-2618.]). The title compounds were prepared as follows:

3-Bromo-2-(phenyl­sulfan­yl)benzo[b]thio­phene (1)

To a Schlenk tube containing 1-(2,2-di­bromo­vin­yl)-2-butyl­sulfanyl­benzene (0.25 mmol, 1.0 equiv.), diphenyl di­sulfide (0.125 mmol, 1.0 equiv.) was added in dry dimethyl sulfoxide (2.0 mL) followed by the addition of cesium carbon­ate (0.244 g, 0.75 mmol, 3.0 equiv.). The reaction system was heated to 383 K and stirred for 1.5 h. Then, the reaction mixture was cooled to room temperature and 2.5 equivalents of NBS (N-bromo­succinimide) in 2 mL of di­chloro­methane were slowly added (2.0 min) into the system. The reaction mixture was stirred at room temperature for 2 h. After this, the reaction solution was diluted in saturated thio­sulfate solution (20 mL) and washed with ethyl acetate (3 × 10 mL). The organic phase was dried over magnesium sulfate and concentrated under reduced pressure. The product was further purified by flash chromatography using hexane as eluent. Colorless needle-shaped single crystals of 1 suitable for X-ray analysis were grown by slow evaporation of a concentrated ethyl acetate solution over several days at room temperature. Yield: 0.066 g (82%); withe solid, m.p. 337–340 K. 1H NMR (CDCl3, 400 MHz) δ (ppm) = 7.77–7.75 (m, 1 H); 7.70–7.68 (m, 1H); 7.58–7.55 (m, 2H); 7.44–7.40 (m, 1H); 7.36–7.30 (m, 4H). 13C{1H} NMR (CDCl3, 100 MHz) δ (ppm) = 141.1, 138.5, 135.9, 133.1, 129.5, 128.3, 126.4, 125.4, 125.2, 123.3, 121.9, 114.4.

3-Iodo-2-(phenyl­sulfan­yl)benzo[b]thio­phene (2)

The first step for obtaining 2 was analogous to that described for 1. The reaction mixture was cooled to room temperature and 1.5 equivalents of I2 in 2 mL of di­chloro­methane were slowly added (2.0 min) into the system. The reaction mixture was stirred at room temperature for 3.5 h. After this, the reaction solution was diluted in saturated sodium thio­sulfate solution (20 mL) and washed with ethyl acetate (3 × 10 mL). The organic phase was dried over magnesium sulfate and concentrated under reduced pressure. The product was further purified by flash chromatography using hexane as eluent. Colorless needle-shaped single crystals of 2 were obtained in the same way of 1. Yield: 0.073 g (79%); yellow solid, m.p. 325–327K. 1H NMR (CDCl3, 400 MHz) δ (ppm) = 7.72 (d, J = 8.0 Hz, 1 H); 7.66 (d, J = 7.6 Hz, 1 H); 7.44–7.40 (m, 2H); 7.34–7.21 (m, 5H). 13C{1H} NMR (CDCl3, 100 MHz) δ (ppm) = 141.5, 141.2, 136.5, 134.7, 130.3, 129.3, 127.7, 126.2, 126.0, 125.5, 122.1, 90.3. MS (Rel. Int.) m/z: 368 (94.3), 240 (100), 120 (50.3), 77 (10.5). HRMS: Calculated mass for C14H9IS2 [M]+: 367.9185, found: 367.9188.

3-Bromo-2-(phenyl­seln­yl)benzo[b]seleno­phene (3)

To a Schlenk tube containing 1-(2,2-di­bromo­vin­yl)-2-butyl­selanyl­benzene (0.25 mmol, 1.0 equiv.), diphenyl diselen­ide (0.125 mmol, 1.0 equiv.) was added in dry dimethyl sulfoxide (2.0 mL) followed by the addition of cesium carbonate (0.244 g, 0.75 mmol, 3.0 equiv.). The reaction system was heated to 384 K and stirred for 0.5 h. Then, the reaction mixture was cooled to room temperature and 2.5 equivalents of NBS (N-bromo­succinimide) in 2 mL of di­chloro­methane were slowly added (2.0 min) into the system. The reaction mixture was stirred at room temperature for 1 h. After this, the reaction solution was diluted in saturated sodium thio­sulfate solution (20 mL) and washed with ethyl acetate (3 × 10 mL). The organic phase was dried over magnesium sulfate and concentrated under reduced pressure. The product were further purified by flash chromatography using hexane as eluent. Colorless needle-shaped single crystals of 3 were obtained in the same way as 1. Yield: 0.081 g (79%); yellow oil. 1H NMR (CDCl3, 400 MHz) δ (ppm) = 7.76 (dd, J = 8.1 and 1.0 Hz, 1H); 7.69–7.66 (m, 3H); 7.41–7.32 (m, 4H); 7.24 (ddd, J = 8.2, 7.3 and 1.3 Hz, 1H). 13C{1H} NMR (CDCl3, 100 MHz) δ (ppm) = 141.1, 140.6, 134.4, 129.6, 129.5, 129.4, 129.0, 125.4, 125.1, 125.0, 124.9, 112.9. MS (Rel. Int.) m/z: 416 (96.8), 336 (100), 256 (42.4), 77 (62.0).

3-Iodo-2-(phenyl­selan­yl)benzo[b]seleno­phene (4)

The first step for obtaining 4 was similar to that described for 3. The reaction mixture was cooled to room temperature and 1.5 equivalents of I2 in 2 mL of di­chloro­methane were slowly added (2.0 min) into the system. The reaction was stirred at room temperature for 1 h. After this, the reaction solution was diluted in saturated sodium thio­sulfate solution (20 mL) and washed with ethyl acetate (3 × 10 mL). The organic phase was dried over magnesium sulfate and concentrated under reduced pressure. The product was further purified by flash chromatography using hexane as eluent. Colorless needle single crystals of 4 were obtained in the same way of (1). Yield: 0.090 g (78%); Orange solid, m.p. 329–331 K. 1H NMR (CDCl3, 400 MHz) δ (ppm) = 7.73–7.64 (m, 4H); 7.41–7.33 (m, 4H); 7.23–7.20 (m, 1H). 13C{1H} NMR (CDCl3, 100 MHz) δ (ppm) = 143.9, 142.2, 134.9, 134.7, 129.8, 129.7, 129.1, 127.6, 125.7, 125.1, 88.9.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
