Oxidation and reductive bromination of Bis(4-tert-butylphenyl)aminoxyl

Golubev,Sen'

, p. 1143 - 1149 (2013/10/01)

One-electron oxidation of bis(4-tert-butylphenyl)aminoxyl with antimony pentachloride and bromine leads to the formation of oxoammonium salts with anions SbCl 6 - and Br 3 - respectively. The salt with the Br 3 - anion converted at heating into a mixture of bromodiphenylamines which formed also from the aminoxyl as a result of previously unknown reaction of three-electron reductive bromination. The mechanisms of these reactions were assumed.
