The 1-decalone anodic oxidation products in alkaline hydroalcoholic medium with platinum anode are identified. The 5-cyclopentyl-5-hydroxypentanoic acidlactone formation evidence a ring contraction process through a carbocationic intermediate.

The reaction of catalytic oxidation of C-5-C-12 alkyl- and cycloalkylcyclopentanones and -cyclohexanones to lactones in a pseudohomogeneous system without the participation of phase transfer agents was investigated. It was established that the catalytic systems prepared on the basis of molybdenum and tungsten blue (MeO (n) Br (m) , where Me = Mo, W, n = 1, 2, m = 2, 3) and H3PO4 deposited on powdered activated carbon AG-3 at 40-60A degrees C, at 5-6 h duration exhibit a high selectivity in the reaction of nucleophilic addition of oxygen to the ketones with the formation of the valero- and caprolactones.
