ABSTRACT:
Processes for preparing substituted 3-aryl-5-haloalkyl-pyrazoles and, alkyl) -4-halo-5-(C.sub.1-3 haloalkyl) -1H-pyrazole-3-yl!-2,4-dihalo-benzoic acids such as isopropyl obenzoate, are presented. The described processes include novel approaches for forming phenyl-diketones, forming and alkylating pyrazoles, brominating heterocyclic compounds, oxidizing alkyl-substituted benzene compounds, and esterifying carboxylic acids. These processes may be combined to prepare 3-aryl-5-haloalkyl pyrazoles, or alternatively, used in subcombinations or individually to prepare intermediates or other useful compounds.
