An electron spin resonance study of the photolysis of tetrafluoro-p-benzoquinone
Abstract
The monoprotonated tetrafluoro-p-benzosemiquinone radical has been prepared from the parent quinone by photochemically induced hydrogen-atom abstraction in a variety of solvents. The radical dissociates readily in hydroxylic solvents and in some cases rapid proton-transfer equilibria were observed which gave time-averaged e.s.r. spectra.
