S,S-Dimethyl-N-(2,4-dinitrophenyl)sulfilimine(4a) has been prepared in good yield by use of DMSO, 2,4-dinitroaniline and phosphorus pentoxide in DMF and the role of DMF in this System is discussed. The method has been applied successfully to the syntheses of several sulfilimines. The reactions of 4a with protonic compounds show an interesting ylide-exchange reaction.
通过在DMF中使用DMSO,2,4-二硝基苯胺和五氧化二磷以高收率制备了S,S-二甲基-N-(2,4-二硝基苯基)亚砜胺(4a),并讨论了DMF在该系统中的作用。该方法已成功应用于几种亚硫亚胺的合成。4a与质子化合物的反应显示出有趣的内酯交换反应。
