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 (aN=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
二苯次磺酰胺 (1) 氧化生成二苯次磺酰胺自由基 (2),并测量其 ESR 和可见光谱。通过与氮核的相互作用,ESR 光谱被分成 1 : 1 : 1 三重峰 (aN=11.26–11.49 G);在一些光谱中,每个三重态都通过与环质子的相互作用进一步分裂(ao-H=ap-H=0.48-0.70,am-H=0.18-0.22 G)。g 值位于 2.0080–2.0083 的范围内。从结果可以得出结论,未成对电子主要分布在氮和两个硫原子上。2 衰变的动力学研究表明, 2 以二级动力学衰变并且对大气氧不敏感。
