In the title compound, C21H13BrO4S·C6H6, the O atom and the phenyl group of the phenylsulfinyl substituent are located on opposite sides of the mean plane of the 5,6-methylenedioxybenzofuran fragment; the phenyl ring is almost perpendicular to this plane [83.66 (6)°]. The 4-bromophenyl ring is rotated slightly out of the 5,6-methylenedioxybenzofuran plane, making a dihedral angle of 2.9 (1)°. The is stabilized by intermolecular C—H⋯O hydrogen bonds and intermolecular C—H⋯π interactions. The also exhibits π–π interactions between the benzene ring and the 4-bromophenyl ring of an adjacent molecule [centroid–centroid distance = 3.586 (3) Å].

77% 3-Chloroperoxybenzoic acid (123 mg, 0.55 mmol) was added in small portions to a stirred solution of 2-(4-bromophenyl)-5, 6-methylenedioxy-3-phenylsulfanyl-1-benzofuran (213 mg, 0.5 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 3 h, 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
(hexane-ethyl acetate, 1:2 v/v) to afford the title compound as a colourless solid [yield 73%, m.p. 462-463 K; Rf = 0.71 (hexane-ethyl acetate, 1:2 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in benzene at room temperature.All H atoms were positioned geometrically and refined using a riding model, with C–H = 0.93 Å for the aryl and 0.97 Å for the methylene H atoms. Uiso(H) = 1.2Ueq(C) for the aryl and the methylene H atoms. The distances of C–C in the solvated benzene ring were restrained to 1.39 (1) Å using command DFIX.

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. |

Benzofuran systems have been received particular attention in the view of their pharmacological properties (Howlett et al., 1999; Twyman & Allsop, 1999). These compounds occur in natural products (Akgul & Anil, 2003; von Reuss & König, 2004). As a part of our ongoing studies of the effect of side chain substituents on the solid state structures of 5,6-methylenedioxy-1-benzofuran analogues (Choi et al., 2007, 2008) we report the crystal structure of the title compound (I) co-crystallized with benzene. The 5,6-methylenedioxybenzofuran unit is planar with a mean deviation of 0.030 (2) Å from the least-squares plane defined by the twelve constituent atoms. The dihedral angle formed by the planes of the 5,6-methylenedioxybenzofuran ring and 4-bromophenyl ring is 2.9 (1)°. The phenyl ring (C16-C21) is almost perpendicular to the plane of 5,6-methylenedioxybenzofuran [83.66 (6)°]. The crystal packing (Fig. 2) is stabilized by intermolecular C–H···O hydrogen bonds between a benzene H atom of the 5,6-methylenedioxybenzofuran ring and the oxygen of the S═O unit, with a C4–H4···O4i (Table 1). The molecular packing (Fig. 3) is further stabilized by intermolecular C–H···π interactions between an H atom of the 4-bromophenyl ring and the furan ring, with a C14–H14···Cg1ii (Table 1; Cg1 is the centroid of the C1/C2/O1/C3/C9 furan ring). The crystal structure (Fig. 3) also exhibits π–π interactions between the benzene ring and the 4-bromophenyl ring of the neighbouring molecules. The Cg2···Cg3v distance is 3.586 (3) Å (Cg2 and Cg3 is the centroids of the C3/C4/C5/C7/C8/C9 benzene ring and the C10-C15 phenyl ring, respectively).
