The [4+2] cycloaddition reactions of 3,6-disubstituted 1,2,4,5-tetrazines with 9-allyl-1,7-,9-allyl-1,2-dicarba-closo-dodecaboranes and 1-allyl-2-isopropyl-1,2-dicarba-closo-dodecab-orane have been studied. The pyridazines containing carborane cage have been synthesized for the first time.

A number of new 3-substituted imidazo[1,2-b][1,2,4,5]tetrazines containing azolyl, aminopyridyl, and alkoxyl substituents was synthesized. These compounds were studied for the biological activity against mycelial anthropophilic and zoophilous dermatophyte fungi (Trichophyton, Microsporum and Epidermophyton), causing diseases of skin and its appendages (hair, nails), and yeast-like fungi Candida.

A range of 3-azolyl-6-methylimidazo[1,2-b][ 1,2,4,5] tetrazines was obtained for the first time by electrophilic heterocyclization of 6-allylamino-3-azolyl- and 3-azolyl-6-propargylamino-1,2,4,5-tetrazines in the presence of HgI2. The structures of the starting materials and final products were confirmed by H-1 and C-13 NMR spectroscopy, elemental analysis, and X-ray structural analysis.
