SYNTHESIS OF IMIDAZO[2,1-b]-1,3,4-THIADIAZOLES IN DABCO AS AN EFFICIENT AND RECYCLABLE CATALYST

An efficient and general method has been described for the synthesis of imidazo[2,1-b]-1,3,4-thiadiazole by the reaction of 2-aminothiadiazoles with phenacyl bromides in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO). The method is suitable for the synthesis of functionalized imidazothiadiazoles.
