✦ Synopsis

Abstract

A facile and general three‐step synthetic route towards unsymmetrical 9‐arylxanthenes was developed. The reaction sequence involves nucleophilic substitution of commercially available 2‐fluorobenzaldehydes with arenoxides, Grignard reaction of the resulting 2‐arenoxybenzaldehydes with arylmagnesium bromides, followed by FeCl~3~‐catalyzed intramolecular diarylmethylation of the resulting carbinols. This strategy was extended to access symmetrical as well as unsymmetrical 9‐arylthioxanthenes.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
