Studies on the Decomposition of Tetra-alkylammonium Salts in Solution. V. Rates and Activation Parameters of Salts Containing Substituted-benzyl or Other Active Groups

Abstract

First order rate constants and activation parameters are reported for the decomposition in chloroform and acetone solvents of a series of 4-substituted-benzylphenyldimethylammonium bromides and iodides and also of a series of tetra-alkylammonium bromides which contain no benzyl group. The results are discussed in terms of general mechanism of these reactions, which are unimolecular "ionic internal" nucleophilic substitutions
