Methyl 2-(5-fluoro-3-methylsulfinyl-1-benzofuran-2-yl)acetate

Abstract

In the title compound, C12H11FO4S, the O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment [O—S—C—C and C—S—C—C torsion angles = 126.70 (13) and −123.55 (13)°, respectively]. The crystal structure is stabilized by weak non-classical intermolecular C—H...O hydrogen-bond interactions. The crystal structure also exhibits aromatic π–π stacking interactions between furan/benzene and benzene/benzene rings of adjacent benzofuran ring systems [centroid–centroid distances = 3.8258 (9) and 3.8794 (9) Å] and a weak intermolecular C—H...π ring interaction.
