(Chemical Equation Presented) Enamides made easy: A catalyst system generated in situ using bis(2-methallyl)-(cycloocta-1,5-diene)ruthenium(II), 1,4-bis(dicyclohexylphosphino)butane, and ytterbium triflate efficiently catalyzes the addition of primary amides to terminal alkynes, selectively forming the Z-anti-Markovnikov enamides. The E isomers are also accessible by combining the hydroamidation with an in situ double-bond isomerization reaction.
