Electron spin resonance spectra of cyclohexadienyl radicals
Abstract
The e.s.r. spectra of a number of radical adducts, [XArH]·, of 1,3,5-tris(trimethylsiloxy)benzene [ArH] have been measured in hydrocarbon solvents; the rate constant for the self-reaction of the radicals is 1·7 × 106 l mol–1 s–1(at –88 °C) when X = PhCO2, and 5·7 × 106 l mol–1 s–1(at –86 °C) when X = F2C.
