Redox-neutral cyanation of C–H bond adjacent to a nitrogen atom was achieved by using the combination of a photoredox catalyst and p-toluenesulfonyl cyanide. The reaction of tetrahydroisoquinolines proceeded smoothly, affording the corresponding cyanated products selectively in good to high yield. Although the reaction rate became slower in the case of the substrates having electron-withdrawing groups, high yields were achieved by elongating the reaction time. Although the yields were only moderate, the reaction conditions were also applicable to N,N-dialkylanilines.

在光氧化还原催化下四氢异喹啉的氧化还原中性CH氰化

的C氧化还原中性氰化-相邻于氮原子H键通过使用photoredox催化剂和的组合实现p甲苯磺酰氰化物。四氢异喹啉的反应进行顺利，选择性地以高产率至高产率提供了相应的氰化产物。尽管在具有吸电子基团的基材的情况下反应速率变慢，但是通过延长反应时间获得了高产率。尽管收率仅中等，但反应条件也适用于N，N-二烷基苯胺。
