By using pyridinium tribromide as the bromo source, an efficient- and practical protocol for the synthesis of C3-brominated imidazo-[1,2- a ]pyridines through ultrasound-promoted and Na 2CO 3-mediated regioselective bromination of im

A convenient halogenation of 2-arylimidazo[1,2-a]pyridines using sodium chloride/bromide/iodide as the halogen sources in the presence of K2S2O8 as an easy-to-handle oxidizing agent was developed. The present work offers a

A systematic study of electrophilic substitution reactions of 3-nitroso-2-arylimidazo[1,2-a]pyridine confirmed that the nitroso group may be ipso-substituted by bromine (NBS in DMF) and that bromine in turn may be substituted by the nitroso group. Electro
