reported. The developed methodology tolerates various functional groups and allows the synthesis of diverse unsymmetrical azophenols under mild conditions in good to excellent yields. A complementary procedure was also investigated by in situ generation of PIFA. This study represents the first general method for the synthesis of o-hydroxyazobenzenes starting from simple azoarenes.
报道了直接的钯催化的偶氮苯的氧化羟基化。所开发的方法可以耐受各种官能团,并允许在温和条件下以良好或优异的收率合成各种不对称的偶氮苯酚。还通过原位生成PIFA研究了一种补充程序。这项研究代表了从简单的偶氮芳烃开始合成邻-羟基偶氮苯的第一种通用方法。
