The spin trapping of tert-butylperoxy and tetralylperoxy radicals by phenyl-N-(tert-butyl)nitrone (PBN) and methyl-N-durylnitrone (MDN) has been investigated.The peroxy radicals were generated by alkoxy radical induced decomposition of hydroperoxides, hydrogen atom abstraction from hydrocarbon in the presence of oxygen, and decomposition of hydroperoxydes by cobaltous ion and lead tetraacetate.The spin adducts of peroxy radicals were observed by ESR and their hyperfine splitting constants were detrmined.The spin adducts of peroxy radicals by MDN could be clearly distinguished from that of alkoxy radical.The nitrone spin adducts of oxygen radicals were found to be reasonably stable at room temperature in the dark, but they decayed readily in the ordinary laboratory light.
