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]
Bis(1,3‐dithiol‐2‐ylidene)‐substituted subtriazachlorin was formed because of an unusual reaction of a 1,3‐dithiole‐2‐one‐fused subphthalocyanine in a triethylphosphite‐mediated tetrathiafulvalene synthesis. In this novel molecule, the bis(1,3‐dithiol‐2‐ylidene)ethane moiety and subtriazachlorin structure are fused, resulting in an electron‐donating ability and broad absorption in the near‐infrared
