The title compound, C15H11ClO3S, was prepared by the oxidation of 5-chloro-2-methyl-3-phenylsulfanyl-1-benzofuran with 3-chloroperoxybenzoic acid. There are two symmetry-independent molecules in the The dihedral angles formed by the phenyl ring and the plane of the benzofuran system are 77.80 (8) and 78.34 (8)°. The is stabilized by aromatic π–π stacking interactions between the furan ring and the benzene rings of neighbouring benzofuran fragments from two symmetry-independent molecules; the centroid–centroid distances within the stacks are 3.689 (4), 3.702 (4), 3.825 (4) and 3.826 (4) Å. Additionally, the stacked molecules exhibit inter- and intramolecular C—H⋯O interactions.

77% 3-chloroperoxybenzoic acid (471 mg, 2.1 mmol) was added in small portions to a stirred solution of 5-chloro-2-methyl-3-phenylsulfanyl-1-benzofuran (275 mg, 1.0 mmol) in dichloromethane (30 ml) at 273 K. After being stirred for 4 h at room temperature, the mixture was washed with saturated sodium bicarbonate solution and the organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuum. The residue was purified by δ 2.80 (s, 3H), 7.28 (d, J = 2.16 Hz, 1H), 7.33 (s, 1H), 7.51–7.55 (m, 2H), 7.58–7.61 (m, 1H), 7.88 (d, J = 2.20 Hz, 1H), 7.98–8.04 (m, 2H); EI-MS 308 [M+2], 306 [M+].

Single crystals suitable for X-ray diffraction were prepared by evaporation of a solution of the I in chloroform at room temperature. Spectroscopic analysis: 1H NMR (CDCl3, 400 MHz)All H atoms were geometrically positioned and refined using a riding model, with C—H = 0.95 Å for aromatic H atoms and 0.98 Å for methyl H atoms, respectively, and with Uiso(H) = 1.2Ueq(C) for aromatic and Uiso(H) = 1.5Ueq(C) for methyl H atoms.

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

This work is related to our communications on the synthesis and structure of 2-methyl-3-phenylsulfonyl-1-benzofuran analogues, viz. 5-bromo-2-methyl-3-phenylsulfonyl-1-benzofuran (Choi et al., 2008a) and 2,5-dimethyl-3-phenylsulfonyl-1-benzofuran (Choi et al., 2008b). Herein we report the crystal and molecular structure of the title compound, 5-chloro-2-methyl-3-phenylsulfonyl-1-benzofuran C15H11ClO3S, (I), (Fig. 1).
The benzofuran unit is essentially planar, with a max deviation of 0.015 (2) Å for unit A, and 0.020 (2) Å for unit B, respectively, from the least-squares plane defined by the nine constituent atoms. In the title compound, the dihedral angles formed by the benzofuran fragment and the plane of the phenyl ring are 77.80 (8)° in unit A and 78.34 (8)° in unit B, respectively. The crystal packing (Fig. 2) is stabilized by four different π–π interactions within each stack of molecules; one between the furan ring (Cg1) and an adjacent benzene ring (Cg2i) [distance 3.702 (4) Å], a second between the furan ring (Cg1) and an adjacent benzene ring (Cg2ii) [distance 3.826 (4) Å], a third between the furan ring (Cg3) and an adjacent benzene ring (Cg4iii) [distance 3.689 (4) Å], a fourth between the furan ring (Cg3) and an adjacent benzene ring (Cg4iv) [distance 3.825 (4) Å], (Cg1, Cg2, Cg3, and Cg4 are the centroids of the O1/C8/C1/C2/C7 furan ring, the C2/C3/C4/C5/C6/C7 benzene ring, the O4/C23/C16/C17/C22 furan ring, the C17/C18/C19/C20/C21/C22 benzene ring, respectively, symmetry code as in Fig. 2). The molecular packing is further stabilized by inter- and intramolecular C—H···O hydrogen bonds (Fig. 3 and Table; symmetry codes as in Fig. 3).
