A new and convenient method has been developed for the synthesis of soluble and polystyrene-supported biguanides by the nucleophilic addition of guanidines such as TMG and TDB to diisopropyl-, dicyclohexyl- and polymericarbodi-imide. These biguanides are excellent catalysts for the transesterification.
