CO2= CO + [O]: recent advances in carbonylation of C-H bonds with CO2

Carbon dioxide (CO2) is an ideal one-carbon source owing to its nontoxicity, abundance, availability, and recyclability. Although the thermodynamic stability and kinetic inertness of CO(2)bring its utilization challenges, many groups have achieved significant progress in the utilization of CO(2)to synthesize valuable carbonyl-containing compounds, which could be also generatedviaoxidative carbonylation of C-H bonds with CO. As CO(2)has a higher oxidation state than CO, it could be considered as a combination of CO and oxidant (CO2= CO + [O]), thus providing a safe, redox-neutral and economic strategy. In this Feature Article, we have summarized the recent advances in carbonylation of C-H bonds with CO(2)based on this concept. The plausible mechanisms of such reactions and future of this field are also discussed.
