An relative eco-friendly protocol for the direct C-3 selenation of imidazo[1, 2-a]pyridines with vorious organoselenides has been developed, gaving the desired products in moderate to excellent yields. Preliminary experimental results are consistent with a C-3 electrophilic functionalization mechanism. The features with relative green reaction conditions, broad substrate scope, and easy scale-up operation would make this strategy promising and important for the preparation of nitrogen and selenium containing molecules.
