The article "Solar Synthesis: Prospects in Visible Light Photocatalysis" by Danielle M. Schultz and Tehshik P. Yoon reviews the recent advancements in visible light photocatalysis, particularly focusing on the use of transition metal complexes to catalyze a wide range of synthetic reactions. The authors highlight the challenges in using visible light for photochemical synthesis due to the limited absorption of organic molecules in the visible spectrum. However, recent research has shown that transition metal complexes, such as ruthenium and iridium, can absorb visible light and facilitate the activation of organic compounds through electron transfer or energy transfer processes. The review discusses the mechanisms of visible light photocatalysis, including the generation of highly reactive intermediates like radicals, radical cations, radical ions, and triplet alkenes. These intermediates exhibit distinct reactivity patterns that enable the synthesis of complex organic structures. The authors provide examples of reactions that have been developed using these intermediates, such as the photoreductive dehalogenation of alkyl halides, the α-alkylation of aldehydes, and the synthesis of bioactive compounds. The article also explores the broader applications of visible light photocatalysis, including its use in polymerization and organometallic chemistry. It highlights the advantages of visible light photocatalysis, such as its mild conditions, functional group tolerance, and control over reaction timing. The authors conclude by discussing the future prospects of visible light photocatalysis, emphasizing its potential to advance synthetic organic chemistry and its synergy with other fields like materials science and drug discovery.The article "Solar Synthesis: Prospects in Visible Light Photocatalysis" by Danielle M.
