aminoxyl radicals

https://doi.org/10.1351/goldbook.A00285
Compounds having the structure R2N–O.mesomer-arrowR2N.+–O; they are @R05066@ derived from @H02913@ by removal of the hydrogen atom from the hydroxy group, and are in many cases isolable. The synonymous terms '@N04172@' and '@N04171@' erroneously suggest the presence of a nitro group; their use is not desirable. E.g. (ClCH2)2N–O. bis(chloromethyl)aminoxyl.
