摘要

Abstract: Elimination reactions of N-(2-(p-nitrophenyl) ethyl) quinuclidinium and (2-(p- nitrophenyl) ethyl) trimethylammonium ions catalyzed by hydroxide ion and buffer bases undergo a change in rate-determining step from an (ElcB), to an (ElcB) R mechanism with increasing buffer concentration in aqueous solution. Exchange of labeled 2H or 3H with solvent was shown for the quinuclidine and trimethylamine derivatives in the presence of ...
