Chromium stearate and chromium acetylacetonate are very active catalysts both for the oxidation of hydrocarbons by molecular oxygen and for the decomposition of organic hydroperoxides. During these reactions they also catalyze the oxidation of secondary alcohols to the corresponding ketones by organic hydroperoxides. From organic hydroperoxides and chromium(III)compounds chromium (VI) compounds are formed which are probably the effective agents oxidizing secondary alcohols to ketones.

In the oxidation of the amino styrenes 1a–1j only products of the oxidative attack at the C  C double bond and hydrolysis products are obtained. Aprotic dipolar solvents and the addition of molecular sieve 5A promote the oxygen uptake. The addition of hydrochinone to the oxidation system does not influence the rate of oxygen absorption or the yields of the oxidation products.

In the autoxidation of 1‐piperidinocyclohex‐1‐ene (1), 1‐piperidinobut‐1‐ene (2), 3‐piperidinopent‐2‐ene (3), and 1‐piperidino‐2‐methyl‐prop‐1‐ene(4) only products of an oxidative attack at the CC‐double bond are formed. Both α‐aminoketones, the products of the rearrangement of primarily formed epoxides, and products of the oxidative session of the CC double bond are obtained. As a side reaction some hydrolysis of the starting enamines takes place. This hydrolysis proves that some water must be formed during the enamine oxidation.
