Ds. Millan et Rh. Prager, THE DEALKYLATION OF TERTIARY ALIPHATIC-AMINES WITH PHENYL CHLOROTHIONOFORMATE, Tetrahedron letters, 39(24), 1998, pp. 4387-4390
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
