Immobilization of Dirhodium Complexes: From Supported to Self-Supported Systems

Herein, we report two strategies to prepare heterogeneous dirhodium catalysts. Synergic immobilized SBA-15~NH₂~COOH+Rh₂ and self-supported Rh₂-bdc coordination polymer are achieved by ligand exchange. The structures are confirmed by solid-state NMR and DNP NMR. The self-supported Rh₂-bdc exhibits superior performance in the model cyclopropanation reaction.
