Cooperative Catalysis: Large Rate Enhancements with Bimetallic Rhodium Complexes
摘要:
A large increase in reaction rate was observed for the catalyzed mono- and dihydroalkoxylation of alkynes when structurally constrained bimetallic Rh(I) catalysts with imidazolyl-imine ligands were compared to their monometallic analogues. The "cooperative" enhancement was vastly improved by restricting the conformational freedom of the bimetallic structure and minimizing the intermetallic Rh center dot center dot center dot Rh distance.
