photocatalytic aerobic oxidation of benzylic C(sp3)–H bonds proceeded in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone, tert-butyl nitrite, and acetic acid. Advantages of this aerobic oxidation method include its relatively mild conditions, the use of visible-light irradiation instead of conventional thermal methods, the use of a low catalyst loading, and the ability to oxidize a range of alkylarenes
在 2,3-二氯-5,6-二氰基-1,4-苯醌、亚硝酸叔丁酯和乙酸存在下,苄基 C(sp3)-H 键的可见光光催化有氧氧化进行。这种有氧氧化方法的优点包括其条件相对温和、使用可见光照射代替传统的热方法、使用低催化剂负载以及能够氧化一系列烷基芳烃,包括呫吨、噻吨和 9 ,10-二氢吖啶,以极好的收率生成相应的酮。
