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.

The 2% cross-linked poly[styrene(iodoso diacetate)] was synthesized, which was applied effectively to the synthesis of pyrazoline derivative, and can be regenerated and reused for the same reaction.
