Radical species produced from the photolytic and pulse-radiolytic degradation of tert-butyl hydroperoxide. An EPR spin trapping investigation

Abstract

The radicals generated during the photolysis of tert-butyl hydroperoxide have been identified by comparison with those generated by reductive pulse radiolysis of the same compound, by photolysis of di-tert-butyl peroxide, and by oxidative degradation of dimethyl sulfoxide. While Bu^tO˙ can definitely be identified as the primary alkoxyl radical intermediate, the identify of the predominantly-formed peroxyl radical is dependent on the generation system.
