Synthesis, structure and insecticidal activity of some novel amides containing N -pyridylpyrazole

A novel series of amides containing N -pyridylpyrazole were designed and synthesized. All of the compounds were characterized and confirmed by IR, 1 H NMR, 13 C NMR, MS and elemental analysis. The single crystal structure of 9d was determined by X-ray diffraction. The bioassay tests showed that the title compounds exhibited good insecticidal activities against Mythimna separata Walker, diamondback moth and Laphygma exigua Hübner.
