Cyclic benzylidene acetals derived from 1,2-and 1,3-diols undergo an efficient ring-opening redox rearrangement to give benzoate esters in the presence of a peroxide initiator and a thiol, which acts as a polarity-reversal catalyst to promote the radical-chain reaction.

The Fries rearrangement of phenyl acetate is catalysed by acidic zeolites such as H-Nu-2 and H-ZSM-5, with selectivities of 2-6:l in favout of para-substituted products. The Fries rearrangement of phenyl esters affords a mixture of o-and phydroxyphenylketones, together with phenol as a hydrolysis p

The photochemical behaviour of 2-methyl-5-nitro-I H-imidazoles 1 in water-containing solutions has been studied. In a first reaction step, the photorearrangement of 1 yields 2-methyl-2-imidazoline-4,5-dione-4-oximes 2. Hydrolysis of 2 and subsequent elimination of water from a supposed intermediate
