(Received 14 August 2012; accepted 4 September 2012; online 8 September 2012)

In the title compound, C17H15IO3S, the 4-methyl­phenyl ring makes a dihedral angle of 76.95 (5)° with the mean plane [r.m.s. deviation = 0.019 (2) Å] of the benzofuran fragment. In the crystal, mol­ecules are linked via pairs of C—H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by slipped π–π inter­actions between the benzene rings of neighbouring mol­ecules [centroid–centroid distance = 3.671 (3) Å and slippage = 1.049 (3) Å].

Comment top

As a part of our ongoing study of 5-iodo-2,7-dimethyl-benzofuran derivatives containing either phenyl-sulfonyl (Choi et al., 2008) or 4-fluorophenyl-sulfonyl (Seo et al., 2012) substituents in 3-position, we report herein the crystal structure of the title compound.

In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.019 (2) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angle between the 4-methylphenyl ring and the mean plane of the benzofuran fragment is 76.95 (5)°. In the crystal structure, molecules are linked via pairs of C—H···O hydrogen bonds (Fig. 2 & Table 1), forming inversion dimers. These dimers are connected by slipped π–π interactions between the benzene rings of neighbouring molecules, with a Cg···Cgii distance of 3.671 (3) Å and an interplanar distance of 3.518 (2) Å resulting in a slippage of 1.049 (3) Å (Fig. 2, Cg is the centroid of the C2–C7 benzene ring).

Experimental top

3-Chloroperoxybenzoic acid (77%, 381 mg, 1.7 mmol) was added in small portions to a stirred solution of 5-iodo-2,7-dimethyl-3-(4-methylphenylsulfanyl)-benzofuran (315 mg, 0.8 mmol) in dichloromethane (50 mL) at 273 K. After being stirred at room temperature for 10h, the mixture was washed with saturated sodium bicarbonate solution, the organic layer was separated and dried over magnesium sulfate. After filtration the solution was concentrated at reduced pressure. The residue was purified by column chromatography (benzene ) to afford the title compound as a colorless solid [yield 68%, m.p. 483–484 K; Rf = 0.56 (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. The positions of methyl hydrogens were optimized rotationally.

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.
