Propene, ozone reaction pathway

Fig. 12-5. Ozone-propene reaction pathways showing oxidation products.

Criegee biradicals formed in the reaction of ozone with alkenes carry significant internal excitation and the majority of them decompose before they can be collisionally stabilized. The biradicals are sufficiently excited that many different rearrangements and decomposition pathways are energetically allowed. For example, in the case of the [CH3C( )H00( )] species formed during propene oxidation the IUPAC panel has recommended the following channels (and yields) [24] ...
