Abstract: 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-HO hydrogen bonds, and by an IO halogen bond with an IO distance of 3.145 (2) Å and a nearly linear C-IO angle of 164.01 (9)°.
