摘要

Abstract

A series of Salen-Co(II) complexes were synthesized to study the effect of O

on the catalytic performance of Salen-Co complexes for the copolymerization of PO/CO

. The Salen-Co(II) complexes showed low activity on the cyclo-addition of CO

to PO with the aid of a cocatalyst such as PPNCl. Unexpectedly

with the addition of O

the activity of Salen-Co(II) complexes was obviously increased and 100% cyclic carbonate was obtained. As the pressure of O

increased

the activity of the complex also increased. With the existence of O

the activity of the complexes was influenced by their structures and the pressure of O

and the complexes with the conjugated structure showed higher activity. The structures of cocatalyst also played a crucial role as for the change of the activity. By altering the electrophilicity of Salen-Co(III)

can also be used as cocatalyst for the copolymerization of PO/CO
