摘要：

Merrifield resin-supported N-3=P(MeNCH2CH2)(3)N shows excellent activity in the transesterification of higher esters such as glyceryl tribenzoate to methyl esters. The catalyst was successfully cycled 20 times (albeit with an increase in reaction time) without compromising yield up to the 20th cycle. The catalyst also showed good performance in amidation reactions of unactivated esters with amino alcohols. (C) 2011 Elsevier Ltd. All rights reserved.
