A novel pesticide intermediates 3-(6-bromo-2-methyl-3-(methylsulfonyl)phenyl)-4,5-dihydroisoxazole was synthesized with 2,3-dimethylaniline as the starting materials. The final product and intermediates were characterized by mass spectra, 1H NMR, infrared and elemental analysis. The crystal structure of compounds 6 and 8 were determined by single crystal X-ray diffraction. Results shown that two oxazole
以2,3-二甲基苯胺为原料合成了新型农药中间体3-(6-溴-2-甲基-3-(甲基磺酰基)苯基)-4,5-二氢异恶唑。最终产物和中间体通过质谱、1H NMR、红外和元素分析进行表征。化合物6和8的晶体结构由单晶X射线衍射确定。结果表明,两种恶唑化合物分别在单斜晶系 (6) 和三斜晶系 (8) 中结晶,空间群分别为 P 21/c 为 6 和 P-1 为 8。合成并表征了2-甲基-3-(甲基磺酰基)苯基)-4,5-二氢异恶唑。
