5-Cyclopentyl-2-(4-fluorophenyl)-3-methylsulfinyl-1-benzofuran

Abstract

In the title compound, C20H19FO2S, the cyclopentyl ring adopts an envelope conformation. The 4-fluorophenyl ring makes a dihedral angle of 27.10 (7)° with the mean plane of the benzofuran fragment. In the crystal, molecules are linked by weak intermolecular C—H...O hydrogen bonds and C—H...π interactions. In the cyclopentyl ring, one C atom is disordered over two orientations with site-occupancy factors of 0.617 (7) and 0.383 (7).
