| titleOfInvention | process for preparing 1-phenylpyrazoles and compound |
| abstract | process for preparing 1-phenylpyrazoles and compound the present invention relates to a process for the preparation of 1-phenylpyrazoles of formula i wherein each R1 is independently selected from chlorine, fluorine, alkyl, haloalkyl, alkoxy and haloalkoxy; n is 1, 2 or 3; each r2 is independently selected from cyano, nitro, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio and alkoxycarbonyl; m is 0, 1 or 2; a is alkyl, aryl or aryl-C1-C4-alkyl, wherein the port optionally has 1, 2, 3 or 4 substituents, which comprises reacting a phenyl halide of formula (li) with a pyrazole derivative of formula ( ili) where x is chlorine, iodine or bromine; and r1, n, r2, m and a are each, as defined above, in the presence of a base and a catalytic system comprising a binder and a metallic compound selected from palladium compounds, iron compounds and copper compounds. |
