Abstract

A series of peroxyl radicals (ROO˙) with substituent groups of varying electron withdrawing power have been investigated using electron paramagnetic resonance spectroscopy. Sixteen carbon-based radicals have been produced, identified and reacted with 17O- labelled molecular oxygen to produce the corresponding peroxyl radical. Carbon-centred radical precursors include alkyl, aromatic, halocarbon, lipid and alcohol radicals. The ...
