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.
