The tandem catalytic functionalization/carboxylation of double as well as triple carbon-carbon bonds with CO₂ represent an emerging research area in synthetic organic methodology. In particular, the combination of mild reaction conditions, stoichiometric acceptor/donorless conditions (visible light photoredox catalysis) and chiral catalysts contributed to a rapid development of this intriguing research area capable of creating chemical diversity/ complexity from readily available unsaturated hydrocarbons and CO₂ as a C1-buinding block. The most recent developments in the field have been collected in the present review article and organized, based on the different sets of π-systems/intermediates/reactive partners employed (i.e., nickelalactones, organo-halides) as well as synthetic strategies (i.e., visible-light photo redox catalysis).

π-系统与 CO2 的串联官能化-羧化反应

双和三碳-碳键与 CO ₂的串联催化功能化/羧化代表了合成有机方法学中的一个新兴研究领域。特别是，温和的反应条件、化学计量的受体/无供体条件（可见光光氧化还原催化）和手性催化剂的组合促进了这个有趣的研究领域的快速发展，能够从容易获得的不饱和烃和 CO ₂创造化学多样性/复杂性，如一个 C1 结合块。该领域的最新发展已在本评论文章中收集并根据所采用的不同 π 系统/中间体/反应伙伴（即、镍内酯、有机卤化物）以及合成策略（即可见光光氧化还原催化）。
