The article describes the synthesis of new modifications of derivatives of 6-phenyl-, 6-piodophenyl- and 6-p-bromophenylimidazo[2,1-b][1,3,4]-thiadiazoles - N -((6-(4-iodophenyl)-2-R-imidazo[2,1-b][1,3,4]-thiadiazol-5-yl)methyl)-alkyl/ heterylamine based on the Mannich reaction, bromination 2((ethylsulfonyl)methyl)-6-phenylimidazo[2,1-b][1,3,4]-thiadiazole and the structure of the resulting compounds was established on the basis of IR spectroscopy. It was shown that the presence of substituents at the 2-nd position of the thiadiazole fragment and substituents at the 5th and 6th positions of the imidazole fragment of this heterocycle cause the appearance of a nonequivalent absorption band in the imidazo-thiadiazole fragment.
