α-Alkylmercapto- und α-Arylmercapto-alkylisocyanate

α-Alkylmercapto- and α-Arylmercapto-alkylisocyanates α-Alkylmercapto- and α-arylmercapto-alkylisocyanates 2 were prepared from α-halosulfides 1 by reaction with silver cyanate. With ammonia, primary or secondary amines they give the corresponding α-mercaptoalkyl-ureas 4 ; with alcohols, the α-mercaptoalkylurethans 3.
