While excellent methods exist for the oxidation of sulfides to sulfoxides R1R2S-->R1R2SO, the azaversion of this atom transfer redox process, i.e., R1R2S-->R1R2S=N-SO2R3, has been less reliable. In sulfilimine synthesis, sulfoxide has been an inevitable byproduct in all cases to date, and the yields of sulfilimine have varied widely. A nearly ideal procedure for the sulfide to sulfonyl sulfilimine
尽管存在将硫化物氧化为亚砜R1R2S-> R1R2SO的出色方法,但是这种原子转移氧化还原过程的氮杂转化,即R1R2S-> R1R2S = N-SO2R3,可靠性较差。迄今为止,在亚硫亚胺合成中,亚砜一直是不可避免的副产物,亚硫亚胺的收率变化很大。描述了将硫化物转化为磺酰基亚硫亚胺的几乎理想的方法。基本上通过简单地在乙腈中将它们一起搅拌,就可以从各种各样的硫化物和种类繁多的已知氯胺盐(R3SO2NClNa)的易于获得的磺酰基亚硝基化合物来源中获得几乎定量的产率。
