Diallyl ethers bearing an enol ether react in the presence of PdCl₂ as catalyst to give a-allyl a-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.
