摘要：
An efficient C-H heteroarylation of heteroarenes is achieved through visible-light photoredox-catalyzed diazotization of heteroarylamines in situ by tBuONO at room temperature. A library of functionalized biheteroaryls is obtained by using this protocol. The reaction avoids the use of transition-metal catalysts, additives, and acidic reaction medium.
