Differding,Bersier
, p. 1595 - 1604 (2007/10/02)
The cyclovoltammetric and polarographic behaviour of nitrogen-fluorine bond containing compounds, including representatitve electrophilic fluorinating agents is described. The reduction potentials are strongly affected by the substituents on the nitrogen

Acyclic secondary fluoroamines and N-nitrosoamines R2NF and R2NNO (R = CH3, C2H5, n-C3H7, i-C3H7, n-C4H9, i-C4H9, c-C6H11) and saturated nonaromatic heterocyclic fluoroamines and N-nitrosoamines R NF and R NNO [R = c-C4H8, c-C5H10, 2,6-(CH3)2-c-C5H8, 2,2,6,6-(CH3)4-c-C5H6] were prepared by reacting trifluoroamine oxide (NF3O) with the respective amine at ≤0 °C in a 1:2 molar ratio. The amine hydrofluoride salts are also formed. Trifluoroamine oxide is a very effective fluorinating and nitrosating reagent and provides an excellent route to >NF- and >NNO-containing compounds. With PF5, 2,2,6,6-(CH3)4-c-C5H6NFgave [CH2CH2CH2C(CH3)2N +=C(CH3)2]PF6-.

Nitroxyl radicals react with perchloryl fluoride with the formation of oxoammonium salts.The kinetics of this reaction in acetonitrile and aqueous methanol were studied by a conductometric method in comparison with the N-fluorination of structural analogs of the nitroxyls (sterically hindered piperidines) by perchloryl fluoride.The reaction has overall second order and first order in each of the reagents, and the reaction rate is 5-7 times lower in a proton-donating medium on account of the specific solvation of the radical center.Data which favor the alternative electrophilic mechanism of oxidation of the nitroxyls, involving the forma tion of an intermediate fluoroammonium radical, are studied in addition to the generally accepted radical mechanism.

The reaction of sterically hindered piperidines with FClO3 in acetonitrile and aqueous methanol is of overall second order and of first order in each of the reagents.The kinetic isotope effect is close to unity.A reaction mechanism involving the formation of a fluoroammonium cation in the controlling stage is proposed.
