Abstract: The title compound, C₁₆H₁₄O₂S, was prepared by the oxidation of 2,5-dimethyl-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 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 intermolecular C-H [pi] interactions between the 5-methyl group and the furan ring of the benzofuran system, and C-HO=S hydrogen bonds.
