Photoredox cooperative N-heterocyclic carbene/palladium-catalysed alkylacylation of alkenes

Abstract

Three-component carboacylation of simple alkenes often requires directing groups and strained substrates. Here, the authors report a photoredox N-heteroyclic carbene/Pd-catalysed alkylacylation of alkenes with aldehydes and unactivated alkyl halides; exogenous photosensitizer or external reductant are not required.
