Abstract: 1. A process for the preparation of substantially pure pyrazole compounds of the general formula see diagramm : EP0012216,P9,F1 where R is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, R**1 is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, R**2 is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, or R**2 together with R is an ortholinked alkylene chain of up to 6 carbon atoms which is unsubstituted or substituted by alkyl of up to 4 carbon atoms, X is chlorine or bromine, and R**3 and R**4 are identical or different and each is hydrogen, alkyl, alkoxy, alkylthio, carbalkoxy or perfluoroalkyl, in each case of up to 4 carbon atoms, or halogen, phenyl, cyano or carboxyl, from the corresponding crude products, characterized in that the crude products are treated with 30 to 90% by weight aqueous solutions of strong acids, thereafter the aqueous solution is separated off and diluted with water, and the pure product which hereupon precipitates is separated from the aqueous fluid.

Abstract: Described is the preparation of 5-dichloroacetyl-3,3,6-trimethyl-9-oxo-1,5- diazabicyclo[4,3,0]nonane (I) by reacting 3,3,6-trimethyl-9-oxo-1,5-diazabicyclo[4,3,0]nonane (II) with dichloroacetyl chloride in the presence of a solvent and a base. The reaction is carried out in a two-phase system comprising a practically water - insoluble solvent and water, and sodium or pota- ssium hydroxide is added as the base in proportion to the amount of dichloroacetyl chloride consumed so that the aqueous phase has a pH of 7 to 9. The solid product formed is then separated off.
