(Received 14 March 2014; accepted 16 March 2014; online 22 March 2014)

In the title compound, C18H17BrO2S, the dihedral angle between the mean planes of the benzo­furan and 4-methyl­phenyl rings is 14.54 (5)°. In the crystal, mol­ecules are linked via pairs of ππ inter­actions between the benzene and 4-methyl­phenyl rings, with centroid–centroid distances of 3.811 (3) and 3.755 (3) Å. A similar inter­action is found between the furan and 4-methyl­phenyl rings, with a centroid–centroid distance of 3.866 (3) Å between neighbouring mol­ecules. The mol­ecules are stacked along the a-axis direction. In addition, a short Br⋯O contact distance of 3.128 (2) Å is observed between inversion-related dimers.

As a part of our continuing study of 5-bromo-3-ethylsulfinyl-7-methyl-1-benzofuran derivatives containing 4-fluorophenyl (Choi et al., 2010a) and 4-chlorophenyl (Choi et al., 2010b) substituents in 2-position, we report here on the crystal structure of the title compound.

In the title molecule (Fig. 1), the benzofuran ring system is essentially planar, with a mean deviation of 0.017 (2) Å from the least-squares plane defined by the nine constituent atoms. The 4-methylphenyl ring is essentially planar, with a mean deviation of 0.004 (1) Å from the least-squares plane defined by the six constituent atoms. The dihedral angle formed by the benzofuran ring system and the 4-methylphenyl ring is 14.54 (5)°.

In the crystal structure (Fig. 2), the molecules are linked via ππ interactions between the benzene and 4-methylphenyl rings, and the furan and 4-methylphenyl rings of neighbouring molecules. The molecules stack along the a-axis direction. The relevant centroid names of ππ stacking interactions are Cg1 for the benzene ring (C2–C7), Cg2 for the furan ring (C1/C2/C7/O1/O8) and Cg3 for the 4-methylphenyl ring (C10–C15). The centroid–centroid separations of Cg1···Cg3ii, Cg1···Cg3iii and Cg2···Cg3ii are 3.811 (2), 3.755 (2) and 3.866 (2) Å, respectively. The symmetry codes are:(ii) -x + 1, -y + 1, -z + 1; (iii)-x + 2, -y + 1, -z + 1. Both interplanar angles between the rings (C2–C7) and (C10–C15)ii as well as (C2–C7) and (C10–C15)iii, and (C1/C2/C7/O1/C8) and (C10–C15)ii equal to 13.90 (5)° and 15.66 (5)°, respectively. This angle is quite large for rings being in π-electron···π-electron interactions as it follows from the study by Janiak (2000) who investigated ππ stacking in metal complexes with aromatic nitrogen ligands. According to Fig. 8 of Janiak's study, the interplanar angles between the rings that are involved in π-electron···π-electron interactions are less than 10° in overwhelming majority of cases. In addition, Br···O halogen-bondings (Politzer et al., 2007) between the bromine atom and the oxygen atom of the SO unit [Br1···O2i = 3.128 (2) Å C4—Br1···O2i = 164.97 (7)°, (symmetry code :(i) - x + 2, - y + 1, - z + 2)] are observed between inversion-related dimers.

Experimental top

3-Chloroperoxybenzoic acid (77%, 224 mg, 1.0 mmol) was added in small portions to a stirred solution of 5-bromo-3-ethylsulfanyl-7-methyl-2-(4-methylphenyl)-1-benzofuran (361 mg, 0.9 mmol) in dichloromethane (25 mL) at 273 K. After being stirred at room temperature for 5h, the mixture was washed with saturated sodium bicarbonate solution and the organic layer was separated, dried over magnesium sulfate, filtered and concentrated at reduced pressure. The residue was purified by column chromatography (hexane–ethyl acetate, 1:1 v/v) to afford the title compound as a colorless solid [yield 71%, m.p. 419–420 K; Rf = 0.51 (hexane-ethyl acetate, 1:1 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in ethyl acetate at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å for aryl, 0.99 Å for methylene and 0.98 Å for methyl H atoms, respectively. Uiso (H) = 1.2Ueq (C) for aryl and methylene, and 1.5Ueq (C) for methyl H atoms. The positions of methyl hydrogens were optimized using the SHELXL-97's command AFIX 137 (Sheldrick, 2008).

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
