| Abstract: | A few of the polyether-linked Heterocyclic carbenes have been synthesized, which have been structurally characterized by element analysis and NMR. Typical catalysts for transesterification reactions are based on either nucleophilic tertiary amines or phosphines. In this paper the use of nucleophilie N-heterocyclic carbenes as efficient transesterifieation catalysts is discussed. The results show that these catalysts have more active than traditional organic nucleophiles in mild condition. |
