Palladium‐Catalyzed Hydroesterification of Alkenes in the Presence of Molecular Hydrogen

摘要

AbstractThe effects of molecular hydrogen on the palladium‐catalyzed alkene‐alcohol‐carbon monoxide and alkene‐formate reactions have been studied. Yields of esters were generally increased, especially in the alkene‐formate reaction, in which an improvement up to 46 yield has been observed. A possible explanation is proposed in which the molecular hydrogen promotes the oxidative addition of formate to palladium. Decarbonylation of formate ester is unlikely to be the ini
