Abstract

To mitigate the growing production of CO2 (a powerful Green House Gas), the scientific community is taking a step beyond CO2 capture/storage and trying to utilize CO2 for the production of chemicals and fuels. Although a number of organic syntheses using carbon dioxide are known, only a few were applied in industry. The direct carboxylation of organic compounds for the formation of the moieties C – COOH and C – COOR is showed in a convincing way through this paper. Moreover, the huge potential of using of carbon dioxide in the catalytic oxidative coupling of methane to C2 hydrocarbons is also presented. The aim of this review is convey some of the potential methods of carbon dioxide utilization as mild oxidant and reagent in the specific case of C – C coupling reactions. Dedicated to Professor George A. Olah and Professor G.K. Surya Prakash for their significant contribution in CO2 utilization
