<i>α</i>-Acylation of Olefins via Photocatalysis

Abstract

The cheap and readily available olefin substrates have received much attention for the synthesis of structurally rich and high value-added ketones, aldehydes, carboxylic acids and their derivatives via α-acylation.Multicomponent tandem α-acylation of olefins achieves high efficiency and selectivity by N-heterocyclic carbene or transition metal catalysis, albeit with narrow reaction modes and substrates.Rapid growth of photocatalysis in organic transformation has introduced new methodologies to undergo the α-acylation of olefins with broad substrate scope.The research progress and prospect for the future development in this active research field is highlighted.
