2,5,7-Trimethyl-3-phenylsulfinyl-1-benzofuran

Abstract

The title compound, C17H16O2S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenylsulfanyl-1-benzofuran with 3-chloroperoxybenzoic 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 nearly perpendicular to the plane of the benzofuran unit [88.30 (9)°] and is tilted slightly towards it. No π–π or C—H...π interactions are observed between neighbouring molecules in the crystal structure because of steric hindrance induced by the three methyl groups.
