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.
Establishment of Heterolytic and Homolytic Y−NO<sub>2</sub> Bond Dissociation Energy Scales of Nitro-Containing Compounds in Acetonitrile: Chemical Origin of NO<sub>2</sub> Release and Capture
The first heterolytic and homolytic N(O)−NO2 bond dissociation energyscales of three types Y−nitro (Y = N, O) compounds and corresponding radical anions in acetonitrile were established by using titration calorimetry combined with relevant electrochemical data through proper thermodynamic cycles.

The oxidation of methylgroups attached to aromatic rings, to give aldehydes and/or carboxylic acids, is a common reaction in organic chemistry. The classic way to obtain the acids is the direct oxidation with a strong oxidant and has been performed under many conditions.l There are limitations, however, and our experience with methylgroups attached to polycyclic heterocycles is that much decomposition
连接到芳环上的甲基氧化生成醛和/或羧酸,是有机化学中的常见反应。获得酸的经典方法是用强氧化剂直接氧化,并已在许多条件下进行。l 但是有局限性,我们对连接到多环杂环上的甲基的经验是,环系统的大量分解伴随着靶向氧化。在转化为醛的各种间接方法中,下面显示的先前报道的 Z 序列具有吸引人的特征。ACHJ ArCHZBr ArCH20N& ACHO

wide variety of alkyl halides with mercury(I) and/or (II) nitrate in 1,2-dimethoxyethane, mercury(II) acetate in acetic acid, aqueous mercury(II) perchlorate, and mercury(II) perchlorate in alcohol solvents have been investigated; as a result, simple high yield procedures for the conversion of alkyl halides into the corresponding nitrate esters, acetate esters, alcohols and ethers have been developed.

The autoxidation of alkylbenzenes can be promoted photochemically in the presence of catalytic amounts of cerim (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)
