The behavior of imidazo[1,2-a]pyridinium, imidazo[1,2-a]pyrimidinium, and imidazo[2,1-b]thiazolium bromides derivatives in oxidative bromination reactions has been studied. It has been established that reaction products structures and their yields depend on the properties of the substituents in the bicycle and the oxidant concentration.

Notes
The term imidazoheterocycles means bicyclic heterosystems, one of the rings of which is imidazole (for example, imidazopyridine, imidazopyrimidine, and imidazothiazole).
