摘　　要：该工作发展了一类二齿N-杂环卡宾(NHC)-吡啶锰配合物催化CO_(2)和环氧化物偶联反应的方法.锰配合物和四丁基碘化铵(TBAI)构成的二元催化体系对环氧化物和CO_(2)合成环状碳酸酯的反应表现出了较高的活性.该二元催化体系适用于广泛的底物范围,例如端环氧化物和高位阻的内环氧化物.通过紫外-可见光谱、红外光谱和高分辨质谱的研究对反应机理进行了阐述.The bidentate N-heterocyclic carbene(NHC)-pyridine nitrogen manganese complex catalyzed coupling reaction of epoxides with CO_(2)was developed.The binary system resulting from the manganese complex Mn-2 in combination with tetrabutylammonium iodide(TBAI)exhibits the high activity for the synthesis of cyclic carbonate from epoxides and CO_(2).The binary catalytic system is suitable for a broad range of substrates scope,such as terminal epoxides and sterically hindered internal epoxides.A possible catalytic pathway was elaborated by UV-vis,FT-IR and HRMS method.
