摘要：
The reaction of Et2Zn with NaOCH2CH2OH yielded a bimetallic zinc complex (NaOCH2CH2OZnEt)-O-.. Its reactions with Ph3SnCl, CP2TiCl2, and CP2LuCl(THF) afforded the corresponding complexes Ph3SnOCH2CH2OZnEt, CP2Ti(OCH2CH2OZnEt)(2), and CP2LuOCH2CH2OZnEt. CP2Ti(OCH2CH2OZnEt)2 catalyzes copolymerization of CO2 with cyclohexene oxide at room temperature and atmospheric pressure; the yield of the polycarbonate is 4 g g(-1) catalyst. Ph3SnOCH2CH2OZnEt is catalytically inert under these conditions, and With CP2LuOCH2CH2OZnEt only the polyether is formed.
