摘要: 
合成一系列吡唑苯酚基鋅及鎂錯合物,以核磁共振光譜及元素分析對錯合物44-49進行鑑定,並進一步以44、47和48之單晶X光繞射數據確認其分子結構。於苯甲醇存在下,以錯合物44-47對L-Lactide及ε-Caprolactone進行開環聚合反應,皆有良好的活性與控制性,並具備Living及Immortal性質。

A series of zinc and magnesium complexes containing pyrazolyl- phenolate ligands have been synthesized. Complexes 44-49 were characterized by NMR spectroscopy and elemental analysis. The molecular structures of complexes 44, 47 and 48 were determined by single-crystal X-ray diffraction techniques. Complexes 44-47 show efficient activity in the ring-opening polymerization of L-lactide and ε-caprolactone in the presence of benzyl alcohol, yielding polymers with controlled molecular weight and narrow molecular weight distribution. They also exhibit both “living” and “immortal” characters.
