氟虫腈的催化氧化合成研究

Research on Synthetic Methods of Fipronil with Catalytic-oxydation

氟虫腈是一高效、广谱的吡唑类杀虫剂,以5-氨基-3-氰基-1-(2,6-二氯-4-三氟甲基苯基)-吡唑为原料,经硫氰化、缩合、催化氧化合成了氟虫腈。

Fipronil is a highly active, broad-SpeCtrum pyrazole insecticide,We synthesized fipronil through the processes of sulfur-cyanidation,condensation and catalytic-oxydafion from 5-amino-3-cyano-1-（2,6-dichloro-4-trifluoromethy1 pheny1）-pyrazole.
