Polymer-Supported 4-Aminoformoyldiphenylammonium Triflate (PS-AFDPAT): An Efficient, Recoverable and Recyclable Cat- alyst for Esterification of Carboxylic Acids with Equimolar Amounts of Alcohols

摘要

Polymer-supported 4-aminoformoyldiphenylammonium triflate (PS-AFDPAT) is an efficient catalyst for the esterification be- tween equimolar amounts of caboxylicacids and alcohols un- der mild conditions, which can be recycled without loss of ac- tivity.
