5-Cyclohexyl-2-(2-fluorophenyl)-3-methylsulfinyl-1-benzofuran

Abstract

In the title compound, C21H21FO2S, the cyclohexyl ring adopts a chair conformation. The 2-fluorobenzene ring makes a dihedral angle of 38.68 (6)° with the mean plane [r.m.s. deviation = 0.018 (2) Å] of the benzofuran fragment. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds into dimers, which are further packed into stacks along the c axis by C—H...O hydrogen bonds. In addition, the stacked molecules exhibit S...O contacts [3.1733 (13) Å] involving the sulfinyl groups. The F atom is disordered over two positions, with site-occupancy factors of 0.961 (3) and 0.039 (3).
