Recently, visible-light photoredox metal dual catalysis has emerged as a powerful and practical strategy to synthesize valuable compounds under mild conditions. The potential for dual copper- and photoredox-catalysis to be used in the pharmaceutical industry is further demonstrated by Lin and Liu as they use this protocol to functionalise a range of heterocycles and drug molecules such as pranoprofen and zaltoprofen in good yields and enantioselectivities (59%-98% and 82%-92% e.e. Photoredox catalysis is a branch of photochemistry that uses single-electron transfer.Photoredox catalysts are generally drawn from three classes of materials: transition-metal complexes, organic dyes, and semiconductors.While organic photoredox catalysts were dominant throughout the 1990s and early 2000s, soluble transition-metal complexes are more commonly used today.
