Summary:Iodine-catalyzed regioselective sulfenylation of imidazo[1,2- a ]pyridines via C(sp 2 )-H bond functionalization has been achieved using sulfonyl hydrazides as a thiol surrogate. A library of 3-sulfanylimidazopyridines with broad functionalities was synthesized under metal and oxidant-free practical reaction conditions. This methodology is also applicable for the regioselective sulfenylation of imidazo[2,1- b ]thiazole and benzo[ d ]imidazo[2,1- b ]thiazole. Iodine-catalyzed regioselective sulfenylation of imidazo[1,2- a ]pyridines via C(sp 2 )-H bond functionalization has been achieved using sulfonyl hydrazides as a thiol surrogate.
