The reaction of 5-amino-3-cyano-1-(2, 6-dichloro-4-trifluoromethylphenyl) -1H-pyrazole and 5-amino-1-[2, 6-dichloro-4-(trifluoromethylphenyl]-4-trifluoromethylsulfinyl-1H-pyrazole-3-carbonitrile (Fipronil) with arylsulfonyl chlorides gave the 5-arylsulfonamides at room temperature in high yields. Some of these compounds had insecticidal activity against pests such as army worm and rice plant hopper.
5-amino-3-cyano-1-(2, 6-dichloro-4-trifluoromethylphenyl) -1H-pyrazole 和 5-amino-1-[2, 6-dichloro-4-(trifluoromethylphenyl]-4-trifluoromethylsulfinyl-1H-pyrazole-3-carbonitrile (Fipronil) 与芳基磺酰氯反应,在室温下得到了高产率的 5-芳基磺酰胺类化合物。其中一些化合物对害虫具有杀虫活性,例如军虫和稻株跳虫。
