hüdroksüülamiinidest R2N–OH hüdroni eemaldamisel tulenevad anioonid H2N–O− ja R2N–O−, nt dimetüülaminoksiid (CH3)2N–O−  , the anion H2N–O−, aminoxide and its N  hydrocarbyl derivatives R2N–O−; formally derived from hydroxylamines , R2N–OH, by removing a hydron  from the hydroxy group, e.g.  (CH3)2N–O−  dimethylaminoxide
