Triphenylphosphinegold(I) triflate catalyzes the conversion of aryl allyl ethers to the corresponding [3,3]- (Claisen) and [1,3]-rearrangement products. The product distribution depends on the stereochemistry of the olefin in the allylic ether as well as the positions and electronic properties of the aryl substituents. Experiments to probe the scope, limitations, and mechanism of this reaction will be discussed.
