Straightforward access to aryl-substituted/fused 1,3-dithiole-2-chalcogenones by Cu-catalyzed C–S coupling between aryl iodides and zinc–thiolate complex (TBA)2[Zn(DMIT)2

Abstract

The Cu-catalyzed C–S coupling between iodoaryl and a zinc–thiolate complex was achieved. This protocol provides a facile and efficient synthetic approach for aryl-substituted/fused 1,3-dithiole-2-chalcogenones, which can be converted to TTFs.
