| 2 | Synthesis,Crystal Structure and Biological Activity of N-tert-butyl-N-(4-methyl-1,2,3-thiadiazole)-5-yl-N’-(4-methyl-1,2,3-thiadiazole)-5-formyl-N’-3,5-dichloropyridin-2-yl-diacylhydrazine显示文摘The title compound N-tert-butyl-N-(4-methyl-1,2,3-thiadiazole)-5-yl-N'-(4-me-thyl-1,2,3-thiadiazole)-5-formyl-N'-3,5-dichloropyrid-2-yl-diacylhydrazines (C18H17Cl2N7O3S2, Mr = 514.41) has been synthesized by the reaction of N-tert-butyl-N'-3,6-dichloropyridine-2-formyl hydrazine with 4-methyl-1,2,3-thiadiazole-5-carbonyl chloride and triethylamine, and its structure was characterized by 1H NMR, HR MS, and single-crystal X-ray diffraction. The crystal of the title compound belongs to monoclinic, space group C2/c with a = 27.726(8), b = 11.045(3), c = 14.507(4), β = 96.758(4)°, Z = 8, V = 4412(2) 3, Dc = 1.549 g/cm3, μ = 0.521 mm-1, F(000) = 2112, R = 0.0405 and wR = 0.1153. X-ray analysis indicates that all rings are non-planar in this molecule. The bioassay results indicate that both the title compound and the positive control RH-5992 have weak fungicide activities, while the title compound has good insecticidal activity against Plutella xylostella L. and no insecticidal activity against Culex pipiens pallens. | 王唤 付一峰 范志金 宋海斌 吴青君 张友军 Belskaya N.P.
