Reaction of N ‐acyl‐3,3‐diamino‐2‐nitroacrylthioamides 1 with MeI at room temperature leads to N ‐acyl‐ S ‐methyl‐3,3‐diamino‐2‐nitroacrylthioimidates 2 in moderate yields. The latter react with Hg(OAc) 2 in DMF yielding 3‐(acylamino)‐3‐amino‐2‐nitroacrylonitriles 8 . The structures of 2a and 8a were established by X‐ray crystallography.
