Aerobic allylic and benzylic oxidations catalyzed by dirhodium(II) complexes with N-hydroxyphthalimide (NHPI) are described. The open flask reaction occurs at mild temperature, using air as the oxidant. Mechanistic studies suggest that dirhodium(II) complexes axially coordinate with NHPI to activate the O-H bond in NHPI and decrease the bond-dissociation energy (BDE).
有氧烯丙基和苄基氧化反应由二钌(II)配合物与 N-羟基邻苯二甲酰亚胺(NHPI)催化。该开瓶反应在温和的温度下进行,使用空气作为氧化剂。机理研究表明,二钌(II)配合物轴向与 NHPI 配位,从而激活 NHPI 中的 O-H 键,并降低键离解能(BDE)。
