可见光促进二氧化碳参与的羧基化反应

二氧化碳是众所周知的温室气体, 也是重要的C1资源, 利用二氧化碳合成高附加值化合物具有重要意义. 其中, 羧酸类化合物广泛存在于天然产物、 药物、 日化品及工业原料中, 是一类非常重要的化合物. 因此, 利用二氧化碳合成羧酸类化合物是一个重要的研究方向; 另一方面, 由于二氧化碳反应活性低, 其转化通常需要高温等苛刻条件. 为解决该问题, 人们利用可见光作为能量来源, 可以在温和条件下实现二氧化碳的高效转化. 鉴于该方向近年来的蓬勃发展, 本文主要对可见光促进二氧化碳参与的羧基化反应进行介绍和总结, 按烯烃、 炔烃、 醛酮、 亚胺和(类)卤代物等重要的化工原料分类阐述, 并将各个反应的特点和机理将作为阐述的重点. 本文也对该领域的未来发展方向进行了展望, 希望为该领域的进一步发展提供参考.

Visible Light-driven Carboxylation with CO2

Carbon dioxide（CO₂） is not only a well-known greenhouse gas but also one important C1 resource. It is very important to realize organic transformations with CO₂ to generate high value-added compounds. Given the importance of carboxylic acid and derivatives which are widely found in natural products， medicines， daily chemicals and industrial raw materials， the synthesis of carboxylic acids with CO₂ has become an important research direction. On the other hand， high temperature and other harsh conditions are always required in this field due to the low reactivity of CO₂. To solve such problems， visible light is used as an clean energy source to drive the effective transformations of CO₂， which has been developed significantly in last few years. This review mainly introduced and summarized the visible light-driven carboxylation with CO₂ in recent years， and classified them according to types of important chemical raw materials， such as alkenes， alkynes， aldehydes and ketones， imines organo（pseudo）halides and others. The characteristics and mechanisms of each reaction were discussed. In addition， this review also provided perspective to this emerging field.
