Butyl 2-(5-iodo-3-methyl­sulfinyl-1-benzofuran-2-yl)acetate

In the title compound, C(15)H(17)IO(4)S, the O atom and the methyl group of the methyl­sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by weak inter­molecular C—H⋯π inter­actions between a methyl H atom of the methyl­sulfinyl group and the benzene ring of the benzofuran system, and by an I⋯O halogen bond of 3.173 (3) Å and a nearly linear C—I⋯O angle of 171.7 (1)°. In addition, the crystal structure exhibits weak inter­molecular C—H⋯O hydrogen bonds. The O atom of the carbonyl group and the butyl chain are both disordered over two positions with site-occupancy factors from refinement of 0.55 (4) and 0.45 (4) (for the O atom), and 0.76 (2) and 0.24 (2) (for the butyl group).
