合成了一种单组分钼催化剂, 并对其在CO2和环氧化物环加成反应中的活性进行了测试. 结果表明, 在80 ℃、0.5 MPa CO2、无溶剂、无助催化剂作为亲核试剂的条件下, 钼催化剂表现出高活性和较好的底物范围, 产率为42%~94%. 采用原位红外(in situ IR)、高分辨率质谱(HRMS)和傅里叶红外光谱(FT-IR)对反应机理进行了研究.

A single component molybdenum catalyst was synthesized and its activity in the cycloaddition reaction of CO2 and epoxide was tested. The results show that the molybdenum catalysts exhibit high activity and a broad substrate scope under the reaction conditions of 80 ℃ and 0.5 MPa of CO2, solvent-free, and and no nucleophilic cocatalysts, affording a wide range of cyclic carbonates in yields of 42%~94%. The reaction mechanism was investigated using in situ infrared (in situ IR), high-resolution mass spectrometry (HRMS) and Fourier transform infrared spectroscopy (FT-IR).

Key words: molybdenum catalyst, epoxide, carbon dioxide, cyclic carbonate
