Ruthenium-Catalyzed Alkene Synthesis by the Decarbonylative Coupling of Aldehydes with Alkynes

摘要

The decarbonylation of aldehydes using [Rh(PPh3)3Cl] was first reported in 1965, originally using stoichiometric amounts of the metal. There are now many examples of catalytic variants of the decarbonylation of an aldehyde 1 to give the decarbonylated product 2 (Scheme 1a).
