(Received 27 October 2010; accepted 28 October 2010; online 6 November 2010)

In the title compound, C16H13ClO3S, the 4-chloro­phenyl ring makes a dihedral angle of 79.96 (5)° with the mean plane of the benzofuran fragment. In the crystal, mol­ecules are linked through weak inter­molecular C—H⋯O and C—H⋯π inter­actions.

Comment top

A series of benzofuran ring system has received much attention in view of their particular pharmacological properties such as antifungal, antimicrobial, antitumor and antiviral activities (Aslam et al., 2006; Galal et al., 2009; Khan et al., 2005). These compounds widely occur in nature (Akgul & Anil, 2003; Soekamto et al., 2003). As a part of our study of the substituent effect on the solid state structures of 3-(4-chlorophenylsulfinyl)-2,5-dimethyl-1-benzofuran analogues (Choi et al., 2010a,b), we report herein on the crystal structure of the title compound.

In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.003 (1 ) Å from the least-squares plane defined by the nine constituent atoms. The 4-chlorophenyl ring makes a dihedral angle of 79.96 (5)° with the mean plane of the benzofuran ring. The crystal packing (Fig. 2) is stabilized by weak intermolecular C–H···O hydrogen bonds: the first one between a benzene H atom and the furan O atom (Table 1, C6–H6···O1i), and the second one between a methyl H atom and the oxygen of the O═S═O unit (Table 1, C10–H10A···O2ii). The crystal packing (Fig. 2) is further stabilized by an intermolecular C–H···π interaction between the 4-chlorophenyl H atom and the benzene ring (Table 1; C13–H13···Cgiii, Cg is the centroid of the C2–C7 benzene ring).

Experimental top

77% 3-chloroperoxybenzoic acid (269 mg, 1.2 mmol) was added in small portions to a stirred solution of 3-(4-chlorophenylsulfanyl)-2,5-dimethyl-1-benzofuran (346 mg, 1.2 mmol) in dichloromethane (40 mL) at 273 K. After being stirred at room temperature for 6h, 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 (benzene) to afford the title compound as a colorless solid [yield 81%, m.p. 428-429 K; R f = 0.59 (benzene)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in acetone 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 and 0.98 Å for methyl H atoms. Uiso(H) = 1.2Ueq(C) for aryl and 1.5Ueq(C) for methyl H atoms.

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.

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.
