A novel, efficient, economical strategy for the coupling and direct selenation of arylhydrazines to selenides using SeO2 has been developed. Our method employs SeO2 as the selenium source with hydrazines as coupling reactants to generate selenides via dinitrogen extrusion. This reagent also helped to generate ArSesubstitued aniline derivatives via C– H functionalization reaction in good yields. The application of this method in gram scale was also carried out.

二氧化硒促进芳基肼和苯胺的二氮挤出/直接硒化

已经开发出一种新颖，有效，经济的策略，用于使用SeO2将芳基肼偶联并直接硒化成硒化物。我们的方法采用SeO2作为硒源，与肼作为偶合反应物，通过二氮挤压生成硒化物。该试剂还有助于通过C–H官能化反应以高收率生成ArSe取代的苯胺衍生物。还进行了该方法在克量表中的应用。
