Abstract
Diphenylammonium triflate (DPAT) efficiently catalyzed esterification betwe en equimolar amounts of carboxylic acids and alcohols in good to excellent yields under mild reaction conditions. Transesterification of carboxylic es ters with a slight excess of alcohols also proceeded using DPAT as catalyst with TMSCl as a co-catalyst. (C) 2000 Elsevier Science Ltd. All rights res erved.
