Abstract: Coordinated tert-butyl peroxy radicals on Co(III) or Fe(IV) abstract from mono- and polyunsaturated fatty acids at ambient temperature in benzene solution hydrogen atom situated at β-position to the double bond. At low concentration of the initiator and in the presence of dissolved oxygen in a narrow temperature range of 10-40°C a 3-line EPR signal with g = 2.0050 is observed. According to analysis of the reaction mechanisms of oxidation this signal is ascribed to the primary pentadienyl free radical transiently stabilized by complexing with molecular oxygen. The interaction of this radical with the spin-trapper DMPO is discussed.
