Condensation of 1‐nitro‐2,2‐bis(methylmercapto)ethylene with aralkylamines gave the 1‐nitro‐2,2‐bis‐(aralkylamino)ethylenes 1 while its reaction with aromatic amines gave the 1‐nitro‐2‐arylamino‐2‐methylmercaptoethylenes 2 under similar conditions. Reactions of methyl 1‐cyano‐2,2‐bis(methyl‐mercapto)acrylate with aromatic amines and hydrazine gave the methyl 1‐cyano‐2‐arylamino‐2–methylmercaptoacrylate
