Dibenzenesulfenamidyl radicals (2) were generated by the oxidation of dibenzenesulfenamides (1), and their ESR and visible spectra were measured. The ESR spectra were split into a 1: 1: 1 triplet by the interaction with the nitrogen nucleus (a N= 11.26– 11.49 G); in some spectra, each of the triplet was further split by the interaction with the ring protons (ao− H= ap− H= 0.48–0.70, am− H= 0.18–0.22 G). The g-values lay in the range ...
