摘要
Synthesis of various cyclic carbonates with yield up to 100% and turn over frequency (TOF) of 351 h(-1) using CO2 and epoxides and a cobalt (III) complex of tetraamidomacrocyclic ligand is described. The catalyst was characterized by single crystal X-ray crystallography. A study of reaction conditions indicates that 2 MPa pressure of CO2 without any co-solvent is sufficient to achieve the desired product.
