2-(4-Iodo­phen­yl)-5,7-dimethyl-3-methyl­sulfinyl-1-benzofuran

摘要

The title compound, C17H15IO2S, was prepared by the oxidation of 2-(4-iodo­phen­yl)-5,7-dimethyl-3-methyl­sulfanyl-1-benzofuran using 3-chloro­peroxy­benzoic acid. The 4-iodo­phenyl ring makes a dihedral angle of 26.0 (1)° with the plane of the benzofuran fragment, and the O atom and the methyl group of the methyl­sulfinyl substituent lie on opposite sides of this plane. The crystal structure is stabilized by inter- and intra­molecular C—H⋯O hydrogen bonds, and by an I⋯O halogen bond with an I⋯O distance of 3.145 (2) Å and a nearly linear C—I⋯O angle of 164.01 (9)°.
