Evidence presented shows that bibenzyl was produced through pyrolysis and photolysis of styrene oxide. This supports McBay's^ postulate that decomposition of styrene oxide results in the production of the alpha styrene epoxidyl free radical, which rearranges to form the phenacyl free radical. Further successive rearrangement and decarbonylation of this radical ultimately results in the formation of bibenzyl. However, photobromination of styrene oxide did not generate the phenacyl free radical requried to produce bibenzyl, rather, polymeric styrene was produced. Also reported is the rearrangements of epoxidyl free radical generated through pyrolysis and photolysis of 2,3 epoxy butane. Pyrolysis at 450C indicated that the resulting epoxidyl radical eventually forms 3,4 dimethyl 2,5 hexane-di-one. The reported results obtained from efforts on the aliphatic epoxidyl radical are thus far inconclusive. The technique for pyrolysis of these epoxides may well be optimized, and these investigations are ongoing. The photolysis of 2,3 epoxy butane under conditions which are effective for the aryl-substituted epoxides was ineffective with this aliphatic epoxide.
