Visible-Light Catalysis

The synthetic community has also seen the emergence of visible-light-driven catalysis, which has had a significant influence on the fields of chemical synthesis, nanotechnology, energy, and biology. Photoredox catalysis has made it possible to find useful synthetic transformations for the development of new drugs over the last ten years. Due to the absence of visible light absorption by organic compounds, which reduces side reactions frequently associated with photochemical reactions carried out with high intensity UV light, the use of visible light sensitization as a method to begin organic reactions is appealing. The quick construction of complex products on the road to new regions of chemical space is made possible by photoredox chemistry, which also enables the formation of new bonds via open shell routes. There are several organocatalysts and transition-metal complexes that can start radical production in the presence of light.
