A metal-free photocatalytic Ritter-type C-H amination of unactivated sp carbons using molecular oxygen as a terminal oxidant has been developed. By employing a co-catalytic system of 3-dichloro-4,5-dicyano-1,4-benzoquinone (DDQ) and -butyl nitrite (TBN), this novel strategy provides a low cost, sustainable and scalable way to synthesise a broad range of secondary amides in moderate to excellent yields under mild conditions.
一种无金属的光催化里特型 C-H 氨化反应，使用分子氧作为末端氧化剂，可实现未活化的 sp 碳键的氨化。通过采用 3-二氯-4,5-二氰基-1,4-苯醌（DDQ）和叔丁基硝酮（TBN）的共催化体系，这种新策略为在温和条件下以中等至优异的收率合成广泛的仲酰胺提供了一种低成本、可持续和可扩展的方法。
