In this work, we achieved a site‐selective amination of 2‐arylimidazoheterocycles on the C3 position using photo‐induced external oxidant‐free strategy. The C−N bond formation with H2 evolution was realized via the oxidative C−H/N−H coupling. This protocol may have significant implications in the late‐modification of complicated drug molecules. In addition, we also used CV and DFT calculations to study
