Electron spin resonance trapping technique with phenyl t-butyl nitrone (PBN) have been used to study the process of electroreduction of p-toluene sulfonamide at mercury electrode. The results showed that the reaction is a free radical one. p-toluene/benzyl radicals formed yia a stage of detaching sulfonamide group have been identified by the hyperfine spectrum of the radical adducts.

Key words: p-toluene sulfonamide, Electroreduction mechanism, Spin trapping technique, p-toluene/Benzyl radicals
