Abstract
Abstract Second-order rate constants () have been measured spectrophotometrically for the reactions of benzyl 2-pyridyl carbonate and-butyl 2-pyridyl carbonate with a series of alicyclic secondary amines in MeCN at. Substrate is much less reactive than and the steric hindrance exerted by the bulky-Bu group in has been attributed to its decreased reactivity. The Br nsted-type plots for the reactions of and are linear with and 0.45, respectively. Thus ...
