摘要

Abstract Treatment of mercapto-heterocyclic compounds with diethyl phosphite in the presence of 4-dimethylaminopyridine (DMAP) in tetrachloroethylene has given the S- ethylated product in good yields and high chemoselectivity. This procedure is compatible with a wide range of SH-compounds such as 1, 3, 4-oxadiazole-2-thiol, 1, 3, 4-thiadiazole-2- thiol, benzo [d] thiazole-2-thiol, and substituted benzenethiol.© 2011 Wiley Periodicals, Inc ...
