  庞大的α-二亚胺钯配合物：在好氧条件下对杂芳烃直接进行C–H键芳基化反应非常有效†

  摘要：

  通过增强主链和N-芳基部分的体积的策略，我们设计并合成了一种体积较大的α-二亚胺钯配合物（即{[Ar–N C（R）–C（R）N– Ar] PdCl 2，（Ar ＝ 2-苯甲酰基-4，6-二甲基苯基）}，C1，R ＝ H；C2，R ＝ An；C3，R ＝ Ph）。这些钯配合物的结构已得到很好的表征，而C1和C3则通过X射线衍射进一步表征。对杂芳烃的直接CH键芳构化筛选了预催化剂的催化性能。二齿N，N-钯络合物C3与两个主链和ñ -芳基膨松性被发现是在有氧条件下高效率的预催化剂。钯负载量低至0.5-0.1 mol％，各种具有挑战性的庞大的空间芳基溴化物和杂芳基溴化物的杂芳烃都适用于这种交叉偶联反应。

  bidentate N,N-palladium complex C3 with both a backbone and N-aryl bulkiness was found to be a highly efficient precatalyst under aerobic conditions. With a low palladium loading of 0.5–0.1 mol%, a variety of heteroarenes with challenging bulky steric aryl bromides as well as heteroaryl bromides are all applicable for this cross-coupling reaction.
