Oxidation of aliphatic cycloalkanols by sodium nitrite in trifluoroacetic acid gave α,ω-dicarboxylic acids in good yields. Adipic acid was obtained in a quantitative yield from cyclohexanol using 1 equiv of sodium nitrite under oxygen atmosphere but the oxidation required more than 3 equiv of sodium nitrite under nitrogen atmosphere. The oxidation method was applicable to the conversion of 1-alkanols to the corresponding carboxylic acids.
A new, modulated, oxidative ring cleavage of α-nitrocycloalkanones by Oxone: Synthesis of α,ω-dicarboxylic acids and α,ω-dicarboxylic acid monomethyl esters

, p. 1049 - 1050 (1998)
By the appropriate choice of the reaction conditions Oxone produces the ring cleavage of α-nitrocycloalkanones affording good yields of α,ω-dicarboxylic acids and α,ω-dicarboxylic acid monomethyl esters, respectively, regardless the ring size and/or the presence of an alkyl group as substituent.
A New Oxidative Cleavage of 2-Nitrocycloalkanones by Hydrogen Peroxide: An Important, Efficient Method for Dicarboxylic Acid or Ketoacid Synthesis
Ballini, Roberto,Marcantoni, Enrico,Petrini, Marino,Rosini, Goffredo
, p. 915 - 917 (1988)
2-Nitrocycloalkanones are smoothly converted into dicarboxylic acids or ketoacids, depending on whether the nitro group is secondary or tertiary, by treatment with aqueous 30percent hydrogen peroxide and potassium carbonate in methyl alcohol solution for 8-10 h at room temperature.
