The carbanions of ethylcyanoacetate, cyanoacetanilide, malononitrile and cyanoacetamide react with Aryl carbamoyl aryl hydrazidoyl cblorides (1 a-f) in ethanol at room temperaturc tc give the corresponding substituted pyrazoles (3a-f, 6a-c, 7a-e and 8a). The structural assignments have been made on the basis of elemental analysis, spectral data and the Chemical evidence fer the resulting pyrazoles. On the other hand, aminoacetonitrile was reacted with (1b) and 9 to give the corresponding substituted triazines (13b) and quinolino [1, 2-f) ] triazone derivative (12). The mechanism of the different reactions wcre discussed.
