Diallyl ethers bearing an enol ether react in the presence of PdCl2 as catalyst to give α-allyl α-alkoxy ketones by selective isomerization via formal 1,2-H migration at the more substituted allyl group, followed by Claisen rearrangement. This rearrangement is also promoted by AuCl3 and IrCl3, although the yields are lower with these catalysts.
