Initially, the release of CO2 was investigated through the photomediated pyrimidopteridine-catalyzed hydro- and deuterodecarboxylation of pharmaceutically relevant carboxylic acids. Furthermore, the thesis outlines an approach for CO2 capture involving the chemical modification of waste material, specifically nylon-6. The methodologies employed in this thesis further involves rational nitrogen-based ligand design.
