Radicals aminoxyl, decomposition

In the presence of NO formed upon decomposition of the tertiary nitroso compounds, the terminal radicals can be converted into terminal nitroso compounds reacting with the adjacent double bond and forming aminoxyl macroradicals ... 

The reaction of arylsulfur radicals with a range of indolinonic and quinolinic aminoxyls has been reported and results indicated that the main products were deoxygenated derivatives formed by initial attack of the sulfur radical on the NO group followed by decomposition to aminyl and arylsulfinyl radicals. ... 

Eventually, alkyl radicals can be randomly produced along the polymer chain after its exposure to irradiations (electron beam or °Co y-ray irradiation). This was demonstrated with a N-phthaloylchitosan (the soluble intermediate for the modification of chitosan) followed by the grafting of either S or Ss s 9.59o stmcture and/or the location of the aminoxyl function was, however, unclear. Holmberg et irradiated poly(vinylidene fluoride) (PVDF) in the presence of TEMPO. The macroinitiator was then used to graft styrene or a styrene/ N-phenylmaleimide mixture onto the PVDF membranes. Such a result was surprising since the alkoxyamine formed should be very stable and not prone to decomposition.
