摘要：
A one-pot protocol has been demonstrated for the regioselective sulfenylation of imidazoheterocycles with disulfides. In this method, thiols are converted to sulfenyl bromides and reacted with 2-phenylimidazo [1, 2-a] pyridines. This simple procedure is highly capable for sulfenylation with readily available starting materials in good to excellent yields under transition metal and base free conditions.
