A review on the CO2 Incorporation Reactions Using Arynes

Arynes are highly reactive and kinetically unstable intermediates, which have been extensively utilized in various carbon-carbon and carbon-heteroatom bond formation reactions. Multi-component couplings of these intermediates are powerful transformations that allow for efficient synthesis of a wide range of carbocycles and heterocycles, as well as natural products. On the other hand, CO2-fixation reactions are one of the safest and most inexpensive methods for the synthesis of various value-added chemicals. Along this line, recently, several elegant multi-component reactions involving arynes were designed for the incorporation of CO2. This review provides a comprehensive overview of the CO2 incorporation reactions using arynes, with the emphasis on the mechanistic aspects of the reactions.
