Ozonolysis of diene 1 in carbon tetrachloride gave exclusively the keto ester 2, while in methanol the keto olefin 17 was the major product.The behavior of model vinyl ethers 3a,b has revealed that a mechanism involving intramolecular oxygen atom transfer from the carbonyl oxide moiety to a methoxyvinyl group is the most probable for the keto ester formation from diene 1.

By identification of the 18O isotope label in the oligomeric peroxide obtained by ozonization of a cyclic olefin in the presence of heavy oxygen and also in the product from catalytic isomerization of this peroxide ( the α,ο-dicarboxylic acids or its dimethyl ester ) it was shown that oxygen enters the ozonolysis product when the reaction is carried out in ether solvents.It is suggested that the increased content of active oxygen in the ozonolysis peroxy product is due to oxidation of the ether solvent to form α-hydroperoxide and addition of the latter to the oligomeric zwitterion, solvated by the polar solvents.It was established that the catalytic and thermal isomerization of the oligomeric peroxides and ozonides of cyclic olefins to the α,ο-dicarboxylic acids and ο-formyl carboxylic acids occurs through the oligomeric α-hydroxy peresters and α-hydroxy esters respectively.

The ozonation of the O-methyloximes has been investigated.Besides the corresponding ketones, ketone diperoxides, and N-methoxyamides were produced.The stereochemistry of the ketone diperoxides was studied by the NMR technique.
