Kinetics of reaction of triethylammonium carboxylates with ethyl alpha-halogenoacetate in various solvents

The kinetics of the reaction of ethyl alpha-halogenoacetate with benzoic ac id in the presence of triethylamine in aqueous acetone and in various solve nts have been investigated The rate constant of the reaction is 4-260 times higher in aprotic dipolar solvents than in protic solvents. The simple reg ression and multiple regression of log k(2) with various solvent parameters have led to the conclusion that in addition to the solvent polarity, vario us other solvent properties, together or individually, influence the reacti on rate, (C) 1999 John Wiley C Sons, inc.
