Abstract
An operationally simple palladium-catalyzed isomerization of highly substituted allylic alcohols and alkenyl alcohols is applicable to a broad range of substrates and displays a wide functional group tolerance. Carbonyl compounds can usually be isolated in high chemical yield. Experimental and computational mechanistic investigations provide evidence for a chain-walking process consisting of repeated migratory insertion/β-H elimination sequences.
