Neoteric chemical transformation involving gold based photocatalysis

Gold photocatalysis includes a diverse set of gold-catalyzed processes with essentially distinctive fundamental stages. When photocatalysis and gold catalysis are combined, then it results to change the valence of the gold centre by electron transfer and radical addition without the usage of exogenous oxidants that are stoichiometrically sacrificed. A number of significant organic transformations are made possible by radicals' exceptional compatibility with gold catalysts. The photocatalysis using gold complexes opens up new opportunities for gold chemistry and complements the existing photoredox catalysis techniques admirably. In this review, the achieved transformations for mononuclear gold(I) catalysts (both those with and without a photosensitizer) and dinuclear gold(I) photocatalysts are discussed with a number of fascinating techniques, as well as their significance for organic chemists.
