Separation, recovery and reuse of N-heterocyclic carbene catalysts in transesterification reactions

摘要

A novel and convenient strategy to separate, recover and reuse N-heterocyclic carbene catalysts in transesterification reactions has been developed.rnN-Heterocyclic carbenes (NHCs) have been widely used in chemistry since the first isolation of stable NHCs by Arduengo et al. in 1991.
