摘要

Quaternary phosphonium salts can be used as cocatalysts for the conversion of epoxides and carbon dioxide into cyclic carbonates catalysed by bimetallic aluminium (salen) complexes at ambient temperature and one atmosphere pressure. The phosphonium groups could also be attached onto the salen ligands of the bimetallic aluminium (salen) complex to form one-component catalysts, and in this case the catalytic activity was ...
