The reaction of imidazo[l,2-a]pyridine with bromine has been studied indilute acidic aqueous solution at 25C. The bimolecular rate coefficient forattack by Br2 on the molecular substrate at the 3-position is foundto be Kbi = 1.30( 0.05) x 109 dm3 mol-l s-lWe find pK.(imidazo[l,2-a]pyridine-H+, aq.,25C) = 6.65 and pK,(3-bromoimidazo[l,2-alpyridine-H+,aq.,25C) = 4.95. The latter compound reactswith bromine in aqueous acetate buffer at pH4.

Kinetics, stoichiometry and mechanism in the bromination of aromatic heterocycles. IV. Aqueous bromination of Imidazo[1,2-a]pyridine
