aerobic benzylic C(sp3)−H oxygenations of aromatic hydrocarbons and C3‐substituted indoles were studied by employing a co‐catalytic system of 3DDQ* (DDQ=2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone) and tert‐butyl nitrite. The superior efficiency of these reaction conditions was demonstrated by comparison with the analogous thermal protocol, and a range of substrates could be oxidized catalytically and selectively
通过使用3 DDQ *(DDQ = 2,3-dichloro-5,6-dicyanoano,1,4的共催化系统)研究了芳烃和C3取代的吲哚的光催化好氧苄基C(sp 3)-H氧化苯醌)和亚硝酸叔丁酯。通过与类似的热方案进行比较,证明了这些反应条件的优异效率,并且可以以良好的收率催化和选择性地氧化多种底物。
