  日期：2018.7.6

  A highly site-selective amidation reaction of substituted 2,4-dichloroazines is reported. Palladium acetate/1,1′-bis(diphenylphosphino)ferrocene (dppf) was identified as the optimal catalyst system, producing >99:1 C-2/C-4 selectivity for most examples. The generality of this transformation was demonstrated through a survey of a diverse amide/substituted 2,4-dichloroazine scope, leading to the preparation

  报道了取代的2，4-二氯嗪的高度位点选择性酰胺化反应。乙酸钯/ 1,1'-双（二苯基膦基）二茂铁（dppf）被确定为最佳催化剂体系，在大多数实例中，其生成的C> 2 / C-4选择性> 99：1。通过各种酰胺/取代的2,4-二氯嗪范围的调查证明了这种转化的一般性，从而以良好至极好的收率制备了所需的C-2酰胺化产品。
