Abstract
Phenyl chlorothionoformate reacts rapidly with aliphatic amines at 20 degrees C to give a thiourethane and an alkyl chloride. The urethanes are readily converted to the secondary amine salt by reaction with dim ethyl sulfate, followed by hydrolysis with water. Rates of reaction, a nd alkyl group cleavage selectivity, are comparable to those reported for 1-chloroethyl chloroformate. (C) 1998 Elsevier Science Ltd. All ri ghts reserved.
