Water-Accelerated Claisen Rearrangements

Allyl aryl ethers undergo accelerated Claisen and [1,3] rearrangements in the presence of a mixture of trialkylalanes and water or aluminoxanes. The ratio of ortho-, meta-, and pora-Claisen products depends to a large extent on the presence of water and to a much lesser extent on the nature of the alane.
