contemporaneous dualcatalysis, that selectively couples two highly reactive catalytic intermediates while overcoming competing trapping by stoichiometric reactive species also present in the reaction. The reaction proceeds via the convergence of a vanadium-catalyzed propargylic rearrangement and a palladium-catalyzedallylicalkylation. It generates a variety of α-allylated α,β-unsaturatedketones, which are
