Lower alkanes (ethane, propane, n-butane, n-pentane) are readily oxidi
zed in acetonitrile solvent by H2O2 with vanadate anion - pyrazine-2-c
arboxylic acid (PCA), as the catalyst at 75 degrees C and pressures of
similar to 3 atm to produce predominantly or exclusively ketones (ald
ehydes). Isobutane is transformed selectively into tert-butyl alcohol.
The oxidation of cyclohexane at 26 degrees C in acetone or acetic aci
d is less efficient than in acetonitrile. The reaction does not occur
in tert-butyl alcohol.
