palladium-catalyzed direct arylation of 2-alkyl-imidazo[1,2-a]pyridine with alkynes towards imidazo[5,1,2-cd]indolizines through double C–H functionalization was developed. The catalyst system is an ionic palladium(II) complex bearing amido-functionalized N-heterocyclic carbene and triphenylphosphine ligands. A mere 2.5 mol-% loading of palladium was sufficient for catalyzing the reactions. Copper acetate and n-tetrabutylammonium
