efficient, reusable and stable binaphthyl stabilized Pd‐nanoparticles (Pd‐BNP) catalyzed the direct ortho‐C−H hydroxylation of acetophenone oxime ethers under neutral and phosphine ligand‐free condition has been developed. A readily available, economic, safe and greener oxidant oxone has been used in this direct ortho‐hydroxylation. The scope of the reaction has been studied with various acetophenone oxime
在中性和无膦配体条件下,开发了一种高效,可重复使用且稳定的联萘稳定的钯纳米颗粒(Pd-BNP)催化苯乙酮肟醚的直接邻-C-H羟基化反应。这种直接邻苯二甲醚使用了现成的,经济的,安全的和绿色的氧化剂砜。-羟基化。已经用各种苯乙酮肟醚(包括富电子至缺电子的系统)研究了反应范围,并且该反应仅以高度区域选择性的方式仅提供了单羟基化产物。几个对照实验结果证实了酮是羟基源。Pd-BNP催化剂已重复使用多达五次。异相测试证实了该反应是由异相Pd-BNP催化剂催化的。
