Abstract
Chlorophenyl and 2,4,6-tribromophenyl chlorothionoformates react rapidly with tertiary amines at 20°C to give a thiocarbamate and alkyl chloride.The thiocarbamates are converted to the secondary amine salts by treatment with dimethyl sulfate, followed by hydrolysis with water. Rates of reaction, and alkyl group clevage selectivity in amines were found to be comparable or superior to those previously reported with chloroformates.
