摘要

Abstract Rates of hydride transfer from several hydride donors to benzhydrylium ions have been measured at 20 C and used for the determination of empirical nucleophilicity parameters N and s N according to the linear free energy relationship log k 20 C= s N (N+E). Comparison of the rate constants of hydride abstraction by tritylium ions with those calculated from the reactivity parameters s N, N, and E showed fair agreement. Therefore, ...
