SYNTHESIS AND REARRANGEMENT OF 5-ISOTHIOCYANATOPYRAZOLINES

1-(3-Iminoprop-1-enyl)-5-isothiocyanato-2-pyrazolines have been synthesized by reaction of hydrazine derivatives with carbon disulfide.These pyrazoline derivatives are precursors of pyrimidinylpyrazoles.

Reaction of Azines with Nitriles

A new method for the synthesis of the hydrazine derivatives (3) by reaction of azines with nitriles is described; the hydrolysis of (3) yields the 3H-pyrazolopyrimidines (4).
