Abstract

Currently, more than 40 gigatonnes of CO₂ are released annually into the atmosphere as a result of fossil fuel combustion, causing ocean acidification and climate unpredictability. Anthropogenic CO₂ emission is seemingly hard to diminish in the near future and, therefore, CO₂-capture and sequestration or CO₂-functionalization can be viable solutions to address this issue. To use CO₂ as a chemical feedstock, namely as a C1 building block, it is essential to equip the process with a nucleophilic catalyst or a highly active reagent, as exemplified by Grignard carboxylation reactions and some recent progress in metal-catalyzed reactions. In this lecture, I will display how we can utilize CO₂ not only as a chemical feedstock but also as a molecular catalyst for a stereoselective cyanation reaction, a cyanohydrin formation reaction, transesterficiation and transamidation reaction. These newly developed organic synthesis methodologies led to a development new methods including desalination and plastic degradation. The obtained knowledge will be beneficial in developing new and energy efficient CO₂ capture processes, which are of great importance for human race.
