Visible‐light‐mediated regioselective allylation, benzylation, and silylation of methylene‐malononitriles using allylic/benzylic silane and disilane reagents have been developed, delivering the corresponding allylated, benzylated, and silylated products in moderate to excellent yields. These reactions proceed smoothly with exclusive regioselectivity by employing only an organo‐photoredox catalyst under very mild conditions. A photoredox‐induced radical cation fragmentation is proposed for the generation of the key allylic, benzylic, and silyl radicals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
