The reaction of 3H,6H-1,2-dithiolo1,2-dithiole-3,6-dithione (5) with N,N-dimethyl-p-phenylenediamine gives, depending on the conditions of the reaction, 3H,6H-3-(p-N,N-dimethylaminophenyl-imino)-1,2-dithiolo1,2-dithiole-6-thione (7), and 3H,6H,-2,5-bis-(p-N,N-dimethylaminophenyl)-1,2-thiazolino1,2-thiazoline-3,6-dithione (3d).Catalyzed by Lewis acids, the compound 3d rearranges reversibly into the isomeric 3H,6H-3,6-bis-(p-N,N-dimethylaminophenyl-imino)-1,2-dithiolo1,2-dithiole (4d).The Dimroth type rearrangement of 3d into 4d occurs also on irradiation.
