Herein, we developed a Ru(II)(BPGA) complex that could be used to catalyze chemo- and site-selective C-H oxidation. The described ruthenium complex was designed by replacing one pyridyl group on tris(2-pyridylmethyl)amine with an electron-donating amide ligand that was critical for promoting this type of reaction. More importantly, higher reactivities and better chemo-, and site-selectivities were
本文中,我们开发了可用于催化化学和位点选择性CH氧化的Ru(II)(BPGA)络合物。所描述的钌络合物是通过用给电子的酰胺配体取代三(2-吡啶基甲基)胺上的一个吡啶基而设计的,该供电子对促进这种类型的反应至关重要。更重要的是,对于使用顺式钌配合物而不是反式-钌配合物的反应,观察到更高的反应性以及更好的化学和位点选择性。该反应可用于将包括天然产物在内的各种有机底物的空间位阻较少的亚甲基和/或亚甲基CH键转化为有价值的醇或酮产物。
