KINETICS OF REACTION OF TRIETHYLAMMONIUM CARBOXYLATES WITH PROPORTIONAL-TO-HALOGENO CARBONYL-COMPOUNDS IN ORGANIC-SOLVENTS .4. EFFECTS OF SOLVENTS ON THE REACTION-RATE OF TRIETHYLAMMONIUM BENZOATE WITH PHENACYL BROMIDE

Kinetics of the reaction of triethylammonium benzoate with phenacyl br omide in different dipolar aprotic and protic solvents have been follo wed. The reaction is about 200-400 times faster in aprotic solvent tha n in protic solvent. In aprotic dipolar solvents the carboxylate anion exists as desolvated one whereas in protic solvents the nucleophile i s solvated by hydrogen-bonding thereby decreasing the nucleophilicity of the active species. The correlation or the rate constants with vari ous solvent parameters has been checked.
