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 para-Claisen products depends to a large extent on the presence of water and to a much lesser extent on the nature of the alane.

ortho-hydroxylation of substituted phenolic substrates is reported. In the presence of a phase-transfer catalyst and a base, N-sulfonyloxaziridines react with phenols to give the corresponding 6-alkyl-6-hydroxycyclohexadienone products in moderate to good yields. The reaction proceeds in fair to good yields and excellent chemoselectivity for 2,6-disubstituted phenols, 1-naphthols, and 2-naphthols.
