- Oxiranylcarbinyl radicals from allyloxyl radical cyclization: Characterization and kinetic information via ESR spectroscopy
-
An ESR spin-trapping technique has been used for the detection of oxiranylcarbinyl radicals as discrete reaction intermediates, formed via cyclization of allyloxyl radicals. The latter were obtained by photolysis of the corresponding nitrites, which were generated directly via an exchange reaction between the appropriate allylic alcohols and tert-butyl nitrite (which also acts as the spin-trap). Experiments have also been conducted with the spin-trap 2,4,6-tribromonitrosobenzene, which has allowed a study to be made of the competition between ring closure and β-scission of a variety of allyloxyl species.
