A reaction of aromatichalides bearing electron-withdrawing groups with tertiary amines in the presence of an iridium catalyst under blue light irradiation is described. Products of the aromatic substitution of the halide by the dialkylamino fragment are obtained. The interaction of aryl radicals with tertiary amines to generate zwitterionic radical species is believed to be the key factor responsible

Systematic studies on the behavior of 1,4,2-dithiazolium cations (1) toward various amino compounds (ammonia, aliphatic and aromatic amines, hydrazine, semicarbazide, thiosemicarbazide derivatives, etc.) were performed. The reaction pathway could be classified into three types depending on possible three fission modes of the initially-formed adduct. The main products were 5-imino-1,4,2-dithiazole,
