摘要: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.

摘要:The present invention relates to a novel synthesis method for the formation of carbon-sulfur bonds by the reaction of an organic sulfur-indium complex with nucleophile in the presence of a palladium catalyst. The present invention provides a synthesis method to prepare several kinds of organic sulfides which are difficult to be prepared by the conventional synthesis methods. A short reaction time and quantitative yield are the advantages of this method. In addition, several kinds of organic sulfide can be prepared by the selection of nucleophile and organic sulfur-indium complex to be used.
