Ozonolysis of enol ethers. Part 10. Ozonization of enol ethers from 1,2- and 1,3-dicarbonyl compounds: Direct quantitative synthesis of phthalonic acid anhydride

The results of ozonolyses of enol ethers from 1.2- and 1.3-dicarbonyl compounds presented here strongly indicate that these reactions do not proceed via the established Criegee ozonolysis mechanism for nucleophilic C=C bonds. The quantitative one-step synthesis of phthalonic acid anhydride via ozonolysis of 2-(methoxymethyliden)-1H-inden-1.3(2H)-dione (28a) is described. Furthermore, a revision of the theory of alkene ozonolysis in the presence of tetracyanoethylene (TCNE) is proposed on the basis of a single-electron-transfer (SET) chemistry.
