Ruthenium(II) oxidase catalysis by direct dioxygen‐coupled turnover enabled step‐economical oxidative CH alkenylation reactions at ambient pressure. Versatile ruthenium(II) biscarboxylate catalysts displayed ample substrate scope and proved applicable to weakly coordinating and removable directing groups. The twofold CH functionalization strategy was characterized by exceedingly mild reaction conditions
直接双氧偶联的周转率催化钌(II)氧化酶在环境压力下实现了分步经济的氧化CH烯基化反应。多功能的双羧酸钌(II)催化剂显示出足够的底物范围,并证明适用于弱配位和可除去的导向基团。双重CH官能化策略的特点是反应条件极其温和,并且具有出色的位置选择性。
