Mekabane, Pierre G. and Tabner, Brian J. (1998) An ESR spin-trap study of radicals present during the thermolysis of some di-t-alkyl peroxides. Magnetic Resonance in Chemistry, 36 (11). pp. 826-832. ISSN 0749-1581Full text not available from this repository.
The thermolysis mechanism of di-tert-butyl and di-tert-amyl peroxide was investigated in a variety of solvents employing electron spin resonance in collaboration with the spin-trapping technique. The tert-amyloxyl radical was trapped for the first time during the thermolysis of di-tert-amyl peroxide. The relative ease of -scission of the tert-amyloxyl radical to give propan-2-one and butan-2-one was established as 32:1 at 382 K. In addition, competition reactions indicate that radicals derived from di-tert-butyl peroxide are ca. 5.5 times more reactive than those derived from di-tert-amyl peroxide towards hydrogen atom abstraction from toluene at 382 K.
