Sterically hindered esters were prepared in excellent yields by the use of anion-exchange resins in both biphase and triphase systems. In addition, quantitative yields of a variety of esters were obtained by the displacement reactions of simple aliphatic and aromatic potassium carboxylate salts and alkyl halides in acetone or acetone-water mixtures. Esters prepared in quantitative yields include ethyl hexadecanoate in 95% acetone and ethyl 2,- ...
