Ethyl 2-(3-ethylsulfinyl-5-methyl-1-benzofuran-2-yl)acetate
Abstract
The title compound, C15H18O4S, was prepared by the oxidation of ethyl 2-(3-ethylsulfanyl-5-methyl-1-benzofuran-2-yl)acetate with 3-chloroperoxybenzoic acid. The crystal structure is stabilized by aromatic π–π interactions between the benzene rings of neighbouring molecules [centroid–centroid distance = 3.655 (3) Å] and by three intermolecular C—H...O non-classical hydrogen bonds.
