Polymer-Supported Phosphine-Halogen Complexes - 2 A New Facile Way for Esterification of Carboxylic Acids

Abstract
The easily available complexes of polystyryl diphenyl phosphine with halogens are convenient condensating agents in the esterification of carboxylic acids under very mild conditions. The isolation of the ester by a simple filtration and evaporation process is a further interesting feature of this reaction.
