Thiolacids and Thiolesters

Hydrolysis kinetics for thiolesters deal with triphenylmethyl thiolben-zoates (AalI mechanism), hydrolysis and Ag -assisted n-butylaminoly-sis of ethyl thiolbenzoate, and thiolesters with an activating group attached to the carbonyl group.  

Trifluorothioacetic acid undergoes free-radical and nucleophilic addition to olefins and ketones respectively, paralleling in many ways the well-known reactions of thioacetic acid. Novel uses of thiolesters in synthesis

Reactions of Thiolacids and Thiolesters, Selenolesters, and Tellurolesters.— The well-known reactivity of thiolacids and thiolesters as acylating agents is shared with the selenolesters. A novel acylating agent, 2-benzoylthio-l-methylpyridinium chloride, is effective in aqueous solutions.
