It was found that N-(arylthio)-t-butylaminyls (2) are easily generated by the photolysis of Nt- butylbenzene-sulfenamides (1). The ESR spectra of 2 were split into a 1: 1: 1 triplet by the interaction with the nitrogen nucleus (11.70–11.89 G), and each of the triplet was further split by the ring protons (a oH: 0.89–1.07 G). The g-values of 2 lie in the range from 2.0068– 2.0073. The radicals persist in benzene and it appears that they are not sensitive to the ...
