The catalytic oxidation of benzyl halides to aldehydes and ketones in aqueous media was studied under relatively mild reaction conditions by using phase-transfer catalyst combined with potassium nitrate and 10% aqueous potassium hydroxide solution. As a result, a simple high-yield procedure has been developed. Copyright Taylor & Francis Group, LLC.
HYDROGEN ABSTRACTION FROM THE ISOMERIC CYMENES

The irradiation of cerium (IV) ammonium nitrate in the presence of ortho, meta and para cymene yields products from attack at the methyl group (the nitrates - these ones in 55 to 69percent isolated yield-, the nitro derivatives, and the aldehydes) as well as at the isopropyl group (the acetophenones, not obtained from the ortho isomer), with minimal ring nitration.The formation of bibenzyls on irradiation with t-butyl peroxide of the same substrates is also studied.The mechanisms of the reactions with the NO3 radical, a good electron acceptor, and with the alkoxy radical are contrasted and compared with photochemical hydrogen abstraction by n?* and, respectively, ??* excited states.

The autoxidation of alkylbenzenes can be promoted photochemically in the presence of catalytic amounts of cerium (IV) ammonium nitrate (CAN) under very mild conditions, the efficiency of the process being significantly increased by added acids.It is suggested that the reaction is promoted by NO3 radicals formed in the light induced decomposition of CAN and that Ce(III) may be reoxidized to Ce(IV) by benzylperoxy radicals.
THE ROLE OF NITRATE FREE RADICALS IN THE PHOTOCHEMICAL SIDE-CHAIN NITROOXYLATION OF ALKYLBENZENES BY CERIUM(IV) AMMONIUM NITRATE IN ACETONITRILE
Baciocchi, E.,Giacco, T. Del,Rol, C.,Sebastiani, G. V.
, p. 541 - 544 (2007/10/02)
It is suggested that the reactive species in the CAN-induced photochemical side-chain nitrooxylation of alkylbenzenes is the nitrate radical, which probably acts as one-electron oxidant.
