Series of pyrazolo[1,5-a]pyrimidine derivatives, imidazo[1,2-b]pyrazole derivative and pyrazolo[1,5-b][1,2,4]triazine derivatives were obtained by the initial reaction of 5-(triphenylphosphoranylideneamino)-1H-pyrazole derivative with carbonyl compounds and hydrazonyl halides. The newly synthesized compounds were confirmed by spectral and analytical data.
