Oxidation of dialkylhydroxylamines with no α-hydrogen substituents proceeds in two reversible one-electron steps. The intermediate nitroxyl radical 2 is the stable species under ambient conditions. The more highly oxidised form 1 finds use as

a reagent for the oxidation of alkanols to the carbonyl compound. Standard reduction potentials for these species are give in Table 8.1.
