Reaction of dimethyl N-cyanodithioiminocarbonate and arylamine or alkylamine compounds in the refluxing ethanol solution afforded the according methyl N-substituted-N′-cyanocarbamimidothioates 1–16 in good yields. Compounds 1–16 were characterized by proton nuclear magnetic resonance (1H NMR) and infrared spectroscopies, of which the structures of compounds 1, 2 and 3 (Elgemeie et al. in Acta Cryst
