Abstract
A new and convenient method has been developed for the synthesis of so luble and polystyrene-supported biguanides by the nucleophilic additio n of guanidines such as TMG and TDB to diisopropyl-, dicyclohexyl- and polymericarbodi-imide. These biguanides are excellent catalysts for t he transesterification. (C) 1998 Published by Elsevier Science Ltd. Al l rights reserved.
