The 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 compounds 9‐11 can be formed from one another. The compounds 10a,b react with nickel chloride to the stable complexes 14a,b. In basic medium 10 gives the salt of 3H,3N‐alkylthiocarbamido‐1,2‐dithiole‐4‐thiolate 15, which reacts with methyl iodide to 3H,3N‐alkylimino‐5‐N‐alkylthiocarbamido‐4‐methylthio‐1,2‐dithiole 16.
