It was found that N-(arylthio)-t-butylaminyls (2) are easily generated by the photolysis of N-t-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 (ao-H: 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 atmospheric oxygen.
研究发现N-(芳
硫基)-叔丁基
氨基(2)很容易通过N-
叔丁基苯次磺酰胺(1)的光解生成。 2的ESR光谱通过与氮核(11.70–11.89 G)的相互作用分裂成1:1:1三重态,并且每个三重态进一步被环质子(ao-H: 0.89–1.07 G)分裂)。 2 的 g 值范围为 2.0068–2.0073。这些自由基持续存在于苯中,并且它们似乎对大气中的
氧气不敏感。
