Synthesis and Biological Activity of N-(Substituted) Pyrazol-5-yl-N',N'- Disubstituted Formamidine

Twenty nine N (substituted)pyrazol 5 yl N,N disubstituted formamidines were synthesized. Their structure was conformed by 1H NMR, IR and elemental analysis.The effects of the reaction condition were discussed. The primary bioassay of some of the compounds showed that this kind of compounds have good fungicidal activity to Palo , although no insecticidal activity.
