Oxidation of aldehyde hydrazones with phenyliodine diacetate (PID) generated nitrilimines which were trapped by acrylonitrile to give 1,3-disubstituted 2-pyrazoline-5-carbonitriles in good yields.

Reaction of nitrilimines 2 with fumaronitrile 6 yielded 4-cyanopyrazoles 8 in good yields.The structures of 8 were substantiated by comparison with their regioisomers 5-cyanopyrazoles 5, prepared by addition of 2 to acrylonitrile followed by oxidation of

Direct nitration of substituted benzaldehyde p-nitrophenylhydrazones 1 gave α-nitroarylidene-p-nitrophenylhydrazines 2.Reactions of 2 with nucleophiles result in displacement of the nitrite.Treatment of 2 with potassium thiocyanate gave 5-imino-1,3,4-Δsu
