Abstract
Electron paramagnetic resonance has been used to characterise free rad icals formed by the reaction of photochemically generated tert-butoxyl radicals with a range of methyl substituted cyclopentenones and cyclo hexenones. The spectra have been interpreted using computer analysis a nd simulation and assigned to cyclic allylic and alkyl radicals formed by abstraction of a hydrogen atom. The 1-oxocyclohept-2-en-4-yl radic al derived by abstraction of bromine from 4-bromocyclohept-2-enone exh ibits a temperature dependent EPR spectrum attributed to ring inversio n.
