A regioselective oxidation of allylic C–H bond to C–O bond catalyzed by copper (I) was developed with diacyl peroxides as oxidants. The oxidation of allylic C–H bond was accomplished with good yield and regioselectivity under mild reaction conditions. This method has a broad substrate scope including cyclic olefins, terminal and internal acyclic olefins and allyl benzene compounds. The reaction proceeds by a radical mechanism as suggested by spin trapping experiments.

铜通过C–H活化催化烯烃的区域选择性烯丙基氧化

以二酰基过氧化物为氧化剂，开发了由铜（I）催化的烯丙基CH键至CH键的区域选择性氧化。在温和的反应条件下，烯丙基CH键的氧化反应具有良好的收率和区域选择性。该方法具有广泛的底物范围，包括环烯烃，末端和内部无环烯烃以及烯丙基苯化合物。如自旋俘获实验所建议的，反应是通过自由基机理进行的。
