efficient and facile metal-free, one-pot reaction has been developed to afford diversely substituted N-arylbenzimidazoles through chemoselective in situ generation of N,N′-diarylamidines from arenediazonium salts, nitriles, and free anilines. The advantages of this protocol consist of the operationally easy and simple one-pot procedure under metal-free and mild conditions, the direct use of inexpensive
已经开发了一种高效且简便的无金属单锅反应,可通过化学方法从槟榔二唑鎓盐,腈和游离苯胺中原位生成N,N'-二芳基idine胺,从而提供不同取代的N-芳基苯并咪唑。该协议的优点包括:在无金属和温和条件下操作简单,操作简单的一锅法;直接使用廉价和可商购的化学药品;因此,具有成本效益且更环保。
