5-Iodo-2,7-dimethyl-3-phenylsulfonyl-1-benzofuran

The title compound, C16H13IO3S, was prepared by the oxidation of 5-iodo-2,7-dimethyl-3-phenylsulfanyl-1-benzofuran with 3-chloroperoxybenzoic acid. The phenyl ring makes a dihedral angle of 76.31 (8)° with the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π–π interactions between the furan and benzene rings of neighbouring molecules, and between the benzene rings of neighbouring molecules; the centroid–centroid distances within the stack are 3.700 (4) and 3.788 (4) Å. In addition, the crystal structure exhibits inter- and intramolecular C—H...O interactions, and an I...O halogen bond with an I...O distance of 3.282 (2) Å and a nearly linear C—I...O angle of 165.69 (8)°
