摘要:通过使用常见的廉价亲电氮源(h 2 N-Oso 3H,Hsa).通过这种方法发现富含电子的底物具有最高的反应性.但是,在室温条件下,即使是中等电子贫乏的基材也能很好地耐受.与不受阻碍的基材相比,受阻的基材似乎同样有效.高度缺乏电子的底物在室温下以非常低的收率提供产物,但是在回流温度下获得中等至非常好的收率.我们的方法也适用于几种常见的硼酸衍生物(例如频哪醇酯)的亲电胺化反应.我们证明了它可以与金属-卤素交换反应或各种定向的邻位金属化方案以"一锅"顺序结合使用,以合成具有独特取代模式的芳香胺.Dft研究,结合实验结果,表明该反应通过碱介导的hsa活化发生的,然后发生1,2芳基b-n迁移.这种活化方式对于反应的成功似乎至关重要,并且首次允许在环境温度下对硼酸进行一般的亲电子胺化.
