• It was found that aromatic dithio acids readily reacted with aryl isocyanate at room temperature to give the corresponding mixed thioanhydrides with the general formula of (ArCS·S·CONHAr) in excellent yields as stable crystals. The mixed thioanhydrides reacted with primary amines at room temperature to give the corresponding thioamides and asymmetric ureas, while the reaction with secondary amines gave the corresponging amine salts and asymmetric ureas in good yields. The spectral properties of the mixed thioanhydrides were discussed.
