The reactions of 11 kinds of tetroxans with antimony pentachloride have been investigated.A mixture of ketone (aldehyde) and ester (carboxylic acid) was obtained, the ratio of which was found to depend on the substituents.In the presence of the catalyst cis-3,6-bis(3-benzoylpropyl)-1,2,4,5-tetroxan rearranges to the trans-isomer.In the reaction of some tetroxans with liquid sulphur dioxide, a mixture of ester and ketone was obtained in a molar ratio of 1:1.Reductive ozonolysis of some alkenes in the presence of 10 mol equiv. of sulphur dioxide in methylene chloride gave the corresponding carbonyl compounds in good yields.
