Utilization of CO2 Feedstock for Organic Synthesis by Visible-Light Photoredox Catalysis

Abstract

CO₂ is a highly abundant, green, and sustainable carbon feedstock. Despite its kinetic inertness and thermodynamic stability, the development of various catalytic techniques has enabled the conversion of CO₂ to value-added products such as carboxylic acids, amino acids, and heterocyclic compounds, where visible-light photocatalysis has emerged to be an efficient promoter of these processes. This Minireview covers the progress in the areas of CO₂ incorporation onto organic matters based on the combined venture of renewable resources of CO₂ and light energy with significant emphasis on the last three years' developments.

Keywords: C−C bond formation; carbon dioxide; carboxylation; heterocycles; photoredox catalysis.
