Abstract

Heterogeneous rhodium catalysts supported on phosphorus-rich covalent organic polymers provide a sustainable solution to the scarcity of Rh resources in the chemical industry. We synthesized COP-PPh₃ by utilizing triphenylphosphine as monomers and then supported rhodium on COP-PPh₃ to generate the heterogeneous Rh catalyst COP-PPh₃-RhCl. This catalyst demonstrated excellent catalytic activity and substrate adaptability in alkyne hydrosilylation reactions. Even after five reuse cycles, COP-PPh₃-RhCl maintained high catalytic activity and structural stability, with consistent Rh loading amounts. This approach effectively addresses challenges related to recycling and reusing homogeneous precious metal catalysts, offering a promising strategy to alleviate precious metal scarcity and reduce environmental pollution risks.
