THE SYNTHESIS OF CROSS-LINKED POLY[STYRENE(IODOSO DIACETATE)] AND APPLICATION IN PREPARATION OF PYRAZOLINE
摘要:
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.
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.
