carbonallylation
Carbonallylation is a term encountered in some chemical literature to describe reactions that install an allyl fragment together with another carbon-containing unit onto a substrate in a single operation. It is not a single, universally defined class, and different sources use the term differently. In broad terms, carbonallylation can refer to three-component coupling processes in which an allyl group and a carbon-containing unit are introduced across a substrate, or to carbonylation-allylation sequences in which a carbonyl group is formed or inserted concomitantly with an allylation step. As a result, the exact meaning depends on context and the authors’ preferred terminology.
Mechanistic frameworks for carbonallylation-like processes typically involve transition-metal catalysis, including palladium, nickel, or copper catalysts, and
Scope and challenges vary across reported examples. Key issues include control of regio- and stereoselectivity, compatibility
