- Department of Chemistry, Bbarathidasan University, Tiruchirapalli-620 024 Manuscript received 24 October 1990, revised 24 July 1992, accepted 21 September 1992 Kinetics of the reaction of triethylammonium benzoate with phenacyl bromide in different dipolar aprotic and protic solvents have been followed. The leaction is about 200-400 times faster in aprotic solvent than in protic solvent. In aprotic dipolar solvents the carboxylate anion exists as desolvated one whereas in protic solvents the nucleophile is solvated by hydrogenbonding thereby decreasing the nucleophilicity of the active species. The correlation of the rate constants with various solvent parameters has been checked.
