CO<sub>2</sub>参与构筑C-N, C-C键合成化学品
摘要
The emission of CO<sub>2</sub> continues to cause serious environmental problems, and there has therefore been a considerable increase in the number of researcher working towards the development of new technologies for the capture and utilization of CO<sub>2</sub>. As a green, abundant, cheap and renewable C<sub>1</sub> resource, CO<sub>2</sub> could participate in a wide range of chemical reactions, and could therefore be converted into various value-added chemicals. The conversion of CO<sub>2</sub> into other value-added chemicals therefore represents an important way to use CO<sub>2</sub>, although it contributes very little to reducing the concentration of CO<sub>2</sub> in the Earth's atmosphere. The green features of CO<sub>2</sub>-involved chemical processes are of critical importance from the perspective of sustainable development. However, only a few industrial processes have been reported that use CO<sub>2</sub> as a raw material because CO<sub>2</sub> is thermodynamically stable and chemically inert. To achieve chemical transformations with CO<sub>2</sub>, a high energy input is generally required, which can be achieved using highly reactive chemicals, specific catalytic systems and high temperature/pressure conditions. Based on these rules, research towards the development of CO<sub>2</sub> chemical conversion processes has made great progress. CO<sub>2</sub> has been successfully used as a green C<sub>1</sub> building block for the production of a variety of different value-added chemicals via the construction of C-H, C-C, C-O and C-N bonds. In particular, CO<sub>2</sub> hydrogenation processes and reactions involving the formation of C-O bonds have been widely investigated. Furthermore, the CO<sub>2</sub>-based synthesis of chemicals via the construction of C-N and C-C bonds has recently attracted considerable attention from numerous researchers, and many excellent results have been reported in literature. For example, aziridines, amino alcohols, acety
