Comprehensive Summary A visible‐light‐induced C‐5 selective C—H borylation of imidazo[1,2‐a]pyridines with NHC‐BH3 via Minisci‐type radical borylation reaction has been developed for the first time. The present sustainable protocol provides a new family of regioselectively C5‐borylated imidazopyridines that would otherwise be difficult to prepare. It is a supplement to site‐selective borylation of azines (nitrogen‐containing aromatic heterocycles) and the assembly of sp2 carbon‐boron bond.
