AbstractThe reaction of 3H,6H‐1,2‐dithiolo[4,3‐c]1,2‐dithiole‐3, 6‐dithione (1) with primary aliphatic amines (8a,b) gives 3H,6H‐3,6‐bisalkylimino‐1,2‐dithiolo[4,3‐c]1,2‐ dithiole (9a,b), 3H,3‐N‐alkylamino‐5‐N‐alkylthiocarbamido‐1, 2‐dithiolium‐4‐thiolate (10a,b) and 3H,3‐N‐alkylimino‐4‐alkylamino‐5‐N‐alkylthiocarbamido‐1,2‐dithiole (11a,b). The compounds9‐11can be formed from one another. The compounds10a,breact with nickel chloride to the stable complexes14a,b. In basic medium10gives the salt of 3H,3N‐alkylthiocarbamido‐1,2‐dithiole‐4‐thiolate15, which reacts with methyl iodide
