CONVENIENT SYNTHESIS OF POLYAZA-3,4-BIS(HETEROARYL)PYRAZOLES

Reactions of a new series of bis-enaminones with some N- and C-nucleophiles proved to be convenient routes for syntheses of a variety of novel 3,4-bis(heteroaryl)pyrazoles. The structures of the compounds were elucidated on the basis of their spectral and elemental analyses and by alternative synthesis wherever possible.
