The carbanions of ethyl cyanoacetate, cyanoacetanilide, malononitrile and cyanoacetami- de react with aryl carbamoyl aryl hydrazidoyl chlorides (1 a-f) in ethanol at room temperature to give the corresponding substituted pyrazoles (3 a-f, 6 a-c, 7 a-e and 8 a). The structural as- signments have been made on the basis of elemental analysis, spectral data and the Chemical evidence for the resulting pyrazoles. On the other hand, aminoacetonitriie was reacted with (1 b) and 9 to give the corresponding substituted triazines (13 b) and quinolino 1, 2-f triazine derivative (12). The mechanism of the different reactions were discussed.
