摘    要:合成两种新型三唑-香兰素Schif碱和四种金属配合物。通过元素分析、红外光谱、电导率、电子光谱等手段对所合成的化合物进行结构表征,认为该配合物为21(LM)型的单核配合物,配位环境为金属离子四配位,分别与两个配体酚羟基中的氧和两个氯配位。将其六种化合物作催化剂,催化CO2与环氧乙烷生成碳酸乙烯酯的反应。结果表明,六种催化剂均对该反应有较高的催化活性,选择性单一,配合物催化活性高于配体。初步探讨了该类反应的机理。

关 键 词:三唑-香兰素Schiff碱  金属配合物  催化活性  反应机理

Abstract:Two new Schiff bases and four complexes have been prepared and characterized by elemental analysis,IR and electronic spectra and conductivity.The results indicate that the complexes are mononuclear complexes(L∶M=2∶1)and the coordination of the Schiff bases is through phenolic oxygen and chlorides. For the first time,we have used these compounds as catalysts for the reaction of carbon dioxide with oxirane to ethylene carbonate and studied the catalytic activity and reaction mechanism.The results reveal that Schiff bases and their complexes have good catalytic activity to this reaction.
Keywords:triazole vanillin Schiff bases  metal complexes  catalytic activity  reaction mechanism
