✦ Synopsis

The title compound, C 15 H 11 BrO 2 S, was prepared by the oxidation of 5-bromo-2-methyl-3-phenylsulfanyl-1-benzofuran using 3-chloroperbenzoic acid. The O atom and the phenyl group of the phenylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is almost perpendicular to the plane of the benzofuran fragment [84.61 (6) ] and is tilted slightly towards it. The crystal structure is stabilized by intermolecular aromaticinteractions, with a centroid-centroid distance of 3.622 (3) A for the furan and benzene rings, C-HÁ Á ÁO hydrogen bonds and a BrÁ Á ÁO (-antibondng of S O to -non-bonding of Br) interaction, with a distance of 3.204 (2) A ˚.
