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.

CATALYSIS OF THE CYCLOHEXADIENONE-PHENOL REARRANGEMENT BY A LEWIS-ACIDIC CLAY SYSTEM

The Fe(3+)-doped acidic K10 clay accelerates greatly, by factors of 105-106, the title reaction.These rearrangements thus occur in a few minutes at room temperature, according to and pathways.
