, p. 1257 - 1261 (2018)
A practical, safe, and scalable synthesis of the stable nitro-oxide radical catalyst ABNO was developed. This process is chromatography-free and avoids the Wolff-Kishner reduction. 1H NMR data for this paramagnetic compound were obtained that allowed an assessment of its chemical purity. Impact sensitivity test data for solid ABNO are also reported.
Long-Lived Trialkylamine Radical Cations Containing Cα-H Bonds in Acyclic Alkyl Groups
Nelsen, Stephen F.,Cunkle, Glen T.
, p. 3701 - 3705 (1985)
Chemical reversibility is observed in the cyclic voltammogram of 9-neopentyl-9-azabicyclononane (3), allowing measurement of its Eo' value, 0.83 V vs.SCE in acetonitrile.Replacement of the tert-butyl group of 3 by isopropyl or phenyl leads to a much shorter radical cation lifetime, and Eo' could not be reliably measured for the 9-isobutyl or 9-benzyl compounds 6 or 7.The barrier for nitrogen inversion of 3, which must be accompanied by NCH2 rotation, is 12.0 kcal/mol at -10 deg C, 5 kcal/mol higher than the barrier for its 9-ethyl analogue 9.The dihedral angle between Cα-H and the nitrogen p orbital axis in the cation radical is argued to be important in determining cation radical lifetime.Observation of chemical reversibility in the CV of 9-(2-adamantyl)-9-azabicyclononane, 5,required in situ drying of the solvent with alumina, as well as fast scan rates or low temperatures.

-
Paragraph 0047-0049, (2017/06/02)
The invention discloses a preparation method of 2-azanoradamantane-N-Oxyl (Nor-AZADO). The method comprises the following steps: placing acetonedicarboxylic acid, glutaraldehyde and benzylamine in an aqueous hydrophosphate solution, and carrying out condensation and decondensation to obtain 9-benzyl-9-azabicyalo-[3,3,1]-nonyl-3-one; carrying out condensation dehydration on 9-benzyl-9-azabicyalo-[3,3,1]-nonyl-3-one and benzene or benzene ring substituted sulfohydrazide, and adding an alkali to obtain 2-(9-benzyl-9-azabicyalo-[3,3,1]-nonane-3-ylidene)-1-benzene or benzene ring substituted sulfohydrazide sodium/potassium salt; carrying out refluxing ring closing on the 2-(9-benzyl-9-azabicyalo-[3,3,1]-nonane-3-ylidene)-1-benzene or benzene ring substituted sulfohydrazide sodium/potassium salt in an organic solvent to obtain N-benzyl-2-azanoradamantane; debenzylating N-benzyl-2-azanoradamantane to obtain 2-azanoradamantane; and oxidizing 2-azanoradamantane by a peroxide oxidant to obtain the Nor-AZADO. The preparation method has the advantages of great increase of the synthesis yield, greenness and environmental protection, high efficiency, low cost, and easiness in industrial large-scale production.
