Evidence for a (π-allyl)palladium intermediate in the quinone-based palladium-catalysed allylic acetoxylation
Abstract
The mechanism of the quinone-based palladium-catalysed allylic acetoxylation of cyclohexene is studied using 1,2-dideuteriocyclohexene (55–70% D) as substrate; the distribution of the deuterium label in the product, determined by 1H NMR spectroscopy, is that expected for a (π-allyl)palladium intermediate.
