叙述近年来国内外发展的新农药如氟虫腈、溴虫腈、七氟菊酯、四氟苯菊酯、氯氟吡氧乙酸、吡氟禾草灵等相关的含氟中间体的开发,包括对-三氟甲基苯胺、2,6-二氯-4-三氟甲基苯胺、2,6-二氯-4-三氟甲基苯肼、3,5-二氯-4-氨基-6-氟吡啶酚、2,3,5,6-四氟苄醇、2,3,5,6-四氟-4-甲基苄醇、2-氯-5-三氟甲基吡啶、2.3-二氯-5-三氟甲基吡啶和2-(对氯苯基)-5-(三氟甲基)吡咯-3-腈等

Development of Fluorine-containing Intermediates for now Hot Point Pesticides

The development of domestic and foreign new agrochemicals was described, such as fiprinil, transfluthrin, tefluthrin, chlorfenapyr fluazifop and fluroxypyr etc. The preparation method and production in china of fluorine- containing intermediates for these agrochemicals was presented, for example, P-trifluoromethyl aniline, 2,6-dichloro- 4-trifluoro phenylhydrazine, 2,3,5,6-tetrafluoro benzyl alcohol, 1,4-bis(hydroxymethyl)-2,3,5,6-tetrafluoro benzene, 2,3,5,6- tetrafluro-4-methyl benzyl alcohol. 4-methoxymethyl- 2,3,5,6- tetrafluoro benzenemethanol, 2-chloro-5-trifluoro methyl pyridine, 2,3-dlichloro-5- trifluoromethyl pyridine and 2-(4'-chlorophenyl)-5-trifluoro methyl pyrrole-3-nitrile.
