Dual catalysis

Barry Trost and co-workers have reported in JACS on a dual catalysis reaction using a vanadium allenoate and a palladium pi allyl unit to form alpha,beta-unsaturated ketones.

Dual Catalysis

Barry Trost and co-worker have published in JACS on a reaction involving dual catalysis. That is, a palladium catalyst and a vanadium catalyst independently reacting with two separate substrates then the two intermediate metal species join to make the product.  In this case, the palladium catalyst makes a pi-allyl intermediate from an allylic carbonate and the vanadium catalyst rearranges a propargylic alcohol to form an allenoxy vanadium intermediate.
