摘要

Abstract A kinetic study is reported for nucleophilic substitution reactions of benzyl 2-pyridyl thionocarbonate (5b) and t-butyl 2-pyridyl thionocarbonate (6b) with a series of alicyclic secondary amines in at. General-base catalysis, which has often been reported to occur for aminolysis of esters possessing a C= S electrophilic center, is absent for the reactions of 5b and 6b. The Br nsted-type plots for the reactions of 5b and 6b are linear with= 0.29 and ...
