  摘要：

  已开发出一种无金属的非均相光催化系统，用于使用氧气作为氧化剂的高效苄基CH氧化。这种可见光介导的氧化反应利用石墨碳氮化物（gC 3 N 4）作为可回收，无毒且低成本的光催化剂。温和的反应条件可从易于获得的烷基芳族前体中以高收率生成合成和生物学上有价值的异苯并二氢醌，邻苯二甲酸，异喹啉酮，异吲哚啉酮和氧杂蒽。gC 3 N 4的异质性催化系统可轻松回收和循环利用，并可多次使用而不会损失活性。通过在生物活性和具有药物价值的靶标合成中的应用，进一步证明了这种“绿色”方法的综合效用。

  A photoredox and Brønsted acid synergistically catalyzed cross‐dehydrogenative C−O coupling reaction is developed in which isochroman peroxyacetals are formed through sp3 C−H bond peroxidation. The reported method is characterized by its extremely mild reaction conditions, excellent yields, and broad substrate scope. An oxocarbenium ion p‐chlorobenzenesulfonate was speculated to be the reactive intermediate
