Abstract

The catalytic fixation of carbon dioxide (CO2) into value-added products has become one of the most appealing patterns in green chemistry since CO2 could be captured and deployed as a cheap, eco-friendly, and renewable C1 feedstock. For this purpose, a plethora of well-defined catalysts have been developed and applied for this chemical transformation. In this setting, organic bases that are well recognized in catalysis owing to their versatile properties turn out to be potential candidates. This chapter gives a comprehensive account of the utility of homogeneous organic bases for the direct and smooth conversion of CO2 into urea, carbamates, carbonates, polymers, carboxylic acid derivatives, methanol, and heterocycles. For further understanding of the catalytic roles of organic bases during the CO2 fixation, the mechanistic study of these synthetic patterns is also delineated.
