摘要
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 sp(2) carbon-boron bond.
