Preparation of Esters and Amides from Carboxylic Acids by Activation with Dialkyl Phosphite-Carbon Tetrachloride Mixture

Abstract

A simple one pot phase transfer catalytic method is described for the synthesis of carboxylic amides and esters from carboxylic acids and amines or alcohols, respectively. For the activation of the carboxylic acids “in situ” generated phosphoric acid diester chlorides were applied.
