5-Dimethyl-3-phenylsulfinyl-1-benzofuran

The title compound, C16H14O2S, was prepared by the oxidation of 2,5-dimethyl-3-phenyl-sulfanyl-1-benzofuran using 3-chloro-perbenzoic acid. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran system. The phenyl ring is almost perpendicular to the plane of the benzofuran unit [87.72 (6)°] and is tilted slightly towards it. The crystal structure is stabilized by inter-molecular C - H⋯π inter-actions between the 5-methyl group and the furan ring of the benzofuran system, and C - H⋯O=S hydrogen bonds. © International Union of Crystallography 2007.
