atom. The photoreaction by-produced p-sulfanyl, aniline, and o-sulfonyl derivatives presumably through SRN1 mechanism from the p-substituted nitrobenzene, photo-desulfonylation, and photo-Fries rearrangement from the sulfonamide, respectively. Discovery of this photoreaction will expand the scope of the chemistry of nitro and thiol compounds, since the sulfonamides are expected to find extensive applications
摘要 在这里,我们偶然发现硝基苯衍生物与烷基硫醇的光照射在不添加其他试剂的情况下以低产率产生磺酰胺。我们提出了一种新的光反应机理,其中光激发的硝基苯双自由基从HS中夺取一个氢原子,生成的硫基自由基与硝基中的氮原子发生偶联,硝基中的两个氧原子转移到硫原子。光反应副产物对硫酰基、苯胺和邻磺酰基衍生物可能是通过 S RN 1 机制从p分别是磺酰胺的-取代硝基苯、光脱磺酰化和光弗赖斯重排。这种光反应的发现将扩大硝基和硫醇化合物的化学范围,因为磺酰胺有望得到广泛的应用。
