2-(9H-Fluoren-9-ylidenemeth­yl)thio­phene

Abstract

The title compound, C18H12S, contains a thio­phene ring which is disordered by rotation of 180° about the linking C—C bond. The site occupancies of the major and minor components of the disordered ring are 0.900 (3) and 0.100 (3), respectively. In one of these disordered components, the mol­ecule is stabilized by an intra­molecular C—H⋯S hydrogen bond. The compound was synthesized in good yield (80%) by a modified phase-transfer-catalysed condensation of fluorene with thio­phene-2-carbaldehyde
