A sp³ CH bond functionalization and CC bond cleavage were realized by AIBN/O₂ catalyst system, providing a series of benzophenones under mild reaction conditions. The mechanistic study shows that a peroxide intermediate is involved in this transformation, and in the case of diphenylmethanes, the sp³ CC bond is cleaved through the peroxide rearrangement, which might provides a new way to cleave relatively strong CC bond and be applied to more general CC bond activation.

AIBN在存在双氧的情况下引发了苄基sp ³ C H和C C键的官能化

通过AIBN / O ₂催化剂体系实现了sp ³ C H键的官能化和C C键的裂解，在温和的反应条件下提供了一系列的二苯甲酮。机理研究表明，过氧化物中间体参与了这一转变，在二苯基甲烷的情况下，sp ³ C C键通过过氧化物重排而断裂，这可能提供了一种断裂相对较强的C C键并被应用的新方法。更一般的C C键活化。
