coupling (CDC) reaction for the formation of CC and CP bonds is disclosed using a catalytic amount of DDQ (10 mol %) under aerobic conditions (see scheme). This unprecedented environmentally benign strategy of using AIBN (10 mol %) and molecular oxygen to regenerate DDQ exhibits a larger substrate scope. For the first time, an efficient utility of 4‐hydroxycoumarins as pronucleophiles for CDC is presented
公开了在好氧条件下使用催化量的DDQ(10 mol%)形成CC和CP键的氧化交叉脱氢偶联(CDC)反应(参见方案)。使用AIBN(10 mol%)和分子氧来再生DDQ的这种前所未有的环境友好策略显示出更大的底物范围。首次提出了4-羟基香豆素作为CDC亲核试剂的有效用途。
