Selective Oxidation of Secondary Amines to N,N-Disubstituted Hydroxylamines by Choline Peroxydisulfate
Banan, Alireza,Valizadeh, Hassan,Heydari, Akbar,Moghimi, Abolghasem
, p. 2315 - 2319 (2017)
N,N-Disubstituted hydroxylamines were prepared directly from secondary amines by a reliable method using an oxidizing task-specific ionic liquid, choline peroxydisulfate. The operational simplicity, high selectivity, and green reaction conditions, make this method efficient and practical.
Detection of paramagnetic pH-dependent inclusion complexes between β-cyclodextrin dimers and nitroxide radicals

Three's company: The construction of a three-component organic free radical has been obtained with symmetric nitroxides and β-cyclodextrin. Its formation can be reversibly controlled by changing pH or temperature (see scheme).
Revision of the α2H value for N,N-dialkylhydroxylamines based on kinetic and spectroscopic measurements
Astolfi,Greci,Paul,Ingold
, p. 1631 - 1633 (2007/10/03)
Kinetic solvent effects on hydrogen-atom abstraction from N,N-diethylhydroxylamine and N,N-dibenzylhydroxylamine by the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH·) indicated that these compounds are much weaker hydrogen-bond donors than impli
SPIN TRAPPING REACTIONS WITH NITRIC OXYDES, I. DIALKYL NITROXYDES
Gyoer, Miklos,Rockenbauer, Antal,Tuedoes, Ferenc
, p. 3759 - 3762 (2007/10/02)
Dialkyl-nitroxide radicals formed from nitric oxyde, wich trapped two alkyl radicals in consecutive steps, have been detected by Electron Spin Resonance spectroscopy.The structure of radicals was found independent of the way of alkyl radical generation.Stereoselectivity of radical trapping was observed for secondary alkyl radicals with chiral carbons.
RADICAL PRODUCTS OF HYDROXYLAMINES, NITRONES AND SPIN ADDUCTS IN THE PROCESS OF GRADUAL OXIDATION WITH COORDINATED PEROXY-RADICALS
Cholvad, Vlado,Stasko, Andrej,Tkac, Alexander,Buchanenko, Anatolii L.,Malik, Lubomir
, p. 823 - 832 (2007/10/02)
Hydroperoxides and cobalt-coordinated peroxy-radicals oxidize hydroxylamines as e.g.Et2NOH, (PhCH2)2NOH, PhCH2PhNOH to the respective nitrones, and the spin adducts - nitrone and peroxy-radical - are formed.In contrast to hydroperoxides the coordinated peroxy radicals can oxidize the formed spin adducts, the methylene or methine groups next to nitrogen being converted into carbonyl groups.The radical intermediates corresponding to individual steps of the gradual oxidation have been identified by means of EPR spectra.
