Metal-Free Photocatalysts for the Synthesis of Carboxylic acids via Functionalization of Non-Activated C-H bonds and Using CO2 as a Carbon Source.

Renewable energy driven chemistry is necessary for the development of a sustainable economy. As a result, CO2 should not be regarded as a waste rather should be considered as a chemical feedstock. Converting this CO2 into useful fine chemicals and pharmaceuticals will provide access to high-value products from a non-toxic, renewable, and low-cost resource. In fact, visible-light-mediated transformation of CO2 to fine chemicals have already been achieved to promote this concept. However, current methods use expensive and toxic reagents along with expensive transition metal catalysts. In contrast, metal-free catalysts and systems are cheaper in price, use less carbon footprint, and are an interesting avenue to explore. Based on this concept, we would like to achieve carboxylic acids and their derivatives (lactams, lactones) via functionalization of non-activated C-H bonds. It is our strong opinion that in this way CO2-based chemistry can be changed and this should have tremendous impact in economic issues.
