Herein we report a general electrochemical strategy for the Sandmeyer reaction. Using electricity as the driving force, this protocol employs a simple and inexpensive halogen source, such as NBS, CBrCl3, CH2I2, CCl4, LiCl and NaBr for the halogenation of aryl diazonium salts. In addition, we found that these electrochemical reactions could be performed using anilines as the starting material in a one-pot
本文中,我们报告了桑德迈尔反应的一般电化学策略。使用电作为驱动力,该协议采用一种简单且廉价的卤素源,例如NBS,CBrCl 3,CH 2 I 2,CCl 4,LiCl和NaBr进行芳基重氮盐的卤化。另外,我们发现这些电化学反应可以以一锅的方式使用苯胺作为起始原料来进行。此外,该方法的实用性在使用非常便宜的石墨作为电极的多克规模的芳基卤化物的合成中得到了证明。已经进行了一系列详细的机理研究,包括自由基时钟和自由基清除剂研究,循环伏安分析和原位电子顺磁共振(EPR)分析。

example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-couplingreactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong
