Sažetak
By the reaction of cyanoacetamide and acetylacetone we
prepared some new pyrazolo(3,4-b) pyridines (8, Sa, 9) and tetrazolo(
l,5-a) pyridines (6, 12, 16) over several reaction steps. Azido-
tetrazolo isomerisation of tetrazolo (l,5-a) pyridines (6, 12, 16) has
been investigated on the basis of their i. r. and n. m. r. spectra in
three solvents (dimethyl sulfokside, chloroform and trifluoroacetic
acid). Compound 8 can be detected as a tetrazolo tautomer in the
solid state as well as in solutions. Compound 16 in the solid state
exists only in the tetrazolo form, while in solutions it exists in both
forms. Compound 12 in the solid state exists only in the azido form,
while in solutions it exists in both forms.
