The one-electron oxidation of α-(arylazo)triphenylmethanes by cerium(IV) ammonium nitrate (CAN) generated aryl radicals along with the triphenylmethyl cation.When the reaction was carried out in the presence of appropriate radical-trapping agents, such as arenes and olefins, the corresponding addition products were obtained in moderate yield.The oxidation of the arylazo compounds with CAN was accelerated by the addition of acids.

4-X-Phenyloxiranes (X = H, Cl, CF3, NO2) in dichloromethane react with N2O5 to give 1-(4-X-phenyl)ethane-1,2-diol dinitrates and with HNO3 to give 2-(4-X-phenyl)-2-nitroethanols.Both reactions give quantitative yields.Kinetics of both reactions, mostly at
Preparation of Di- and polynitrates by ring-opening nitration of epoxides by dinitrogen pentoxide (N2O5)

Eighteen epoxides of various kinds were reacted with N2O5 in chlorinated hydrocarbon solvents (principally CH2Cl2) to give vicinal nitrate ester products by a novel ring-opening nitration reaction. The procedure offers easier temperature control and simpler isolation procedures compared with conventional mixed acid nitrations; it also enables selective nitration reactions to be carried out on polyfunctional substrates. The scope and limitations of the reaction, as well as those of an alternative route utilising N2O4 with in situ oxidation of an intermediate nitrite-nitrate, are discussed.
NITRATION BY OXIDES OF NITROGEN, PART 1: PREPARATION OF NITRATE ESTERS BY REACTION OF STRAINED-RING OXYGEN HETEROCYCLES WITH DINITROGEN PENTOXIDE
Golding, P.,Millar, R. W.,Paul, N. C.,Richards, D. H.
, p. 2731 - 2734 (2007/10/02)
Epoxides and oxetanes react with dinitrogen pentoxide to give the corresponding dinitrates in high to near quantitative yields.The scope and limitations of the method are briefly discussed.
