generated by the photolysis of benzenesulfenanilides (1) in benzene in the presence of di-t-butyl peroxide or by the oxidation of 1 in benzene with lead dioxide. The ESR spectra of the radicals were completely analyzed by labeling some radicals with deuterium and with the aid of a computer simulation technique. The unpaired electron is distributed mainly on the nitrogen atom and the N-phenyl ring. The values
各种取代的 N-苯基-N-苯硫胺基 (2), Ar-\dotN-S-Ar', 是在二叔丁基过氧化物存在下通过苯亚磺酰苯胺 (1) 在苯中的光解产生的。用二氧化铅在苯中氧化 1。通过用氘标记一些自由基并借助计算机模拟技术,对自由基的ESR光谱进行了完整的分析。未成对电子主要分布在氮原子和N-苯环上。将 aN 的值与哈米特方程中的 σ 或 σ− 作图,发现根据沃尔特标准,2 属于 S 类。
