Four novel [OSSO]-based-Cr(III) complexes (2-5) were synthesized and characterized. Their catalytic activity was investigated in CO2/epoxide coupling reaction in the presence of PPNCl as co-catalyst. Among the reported complexes, catalyst 2 showed the best catalytic activity in the exclusive formation of polycarbonates (PPC, PCHC, PVCH, and PHC) with a selectivity of 83 % and more in all cases.
合成并表征了四种新型[OSSO]基Cr(III)配合物( 2-5 )。在PPNCl作为助催化剂存在下,研究了它们在CO 2 /环氧化物偶联反应中的催化活性。在报道的配合物中,催化剂2在聚碳酸酯(PPC、PCHC、PVCH和PHC)的单独形成中表现出最好的催化活性,在所有情况下选择性均为83%以上。
