Formation and reactivity of arylradicals from cathodic cleavage of halonitrobenzenes and related compounds
The cathodic reduction of 4-halonitrobenzenes (X = I, Br and Cl) was principally followed by means of UV-Vis and electron spin resonance (ESR) spectroscopy. The presence of the dimer radical anion was detected during the course of the electrolysis in several polar solvents and the mode of cleavage of this transient species was clarified by ESR markers.
