Abstract The tandem catalytic functionalization/carboxylation of double as well triple carbon‐carbon bonds with CO 2 represent an emerging research area in synthetic organic methodology. In particular, the combination mild reaction conditions, stoichiometric acceptor/donorless conditions (visible light photoredox catalysis) and chiral catalysts contributed to a rapid development this intriguing capable creating chemical diversity/ complexity from readily available unsaturated hydrocarbons C1‐buinding block. most recent developments field have been collected present review article organized, based on different sets π‐systems/intermediates/reactive partners employed ( i.e. , nickelalactones, organo‐halides) strategies visible‐light photo redox catalysis).
