A CαCβ bond activation of the carbonyl group in unstrained ketones catalyzed cooperatively by palladium and copper(II) with the departure of the acetophenone has been developed, and the subsequent coupling with a variety of aromatics via the formal CH activation similar to the Friedel–Crafts reaction affords the skeleton-reconstructed coumarinderivatives with high regioselectivity.
AC α Ç β在无应变酮羰基的键活化协同催化的钯和铜(II)与苯乙酮的离开已被开发出来,并与多种芳族化合物的随后的偶联通过在正式CH激活类似于弗里德尔–Crafts反应可提供具有高区域选择性的骨架重建香豆素衍生物。
