摘 要：
The present invention relates to a process for the preparation of 5-amino-1-aryl-3-cynopyrazole derivatives of the general formula I wherein W denotes nitrogen or -CRe4 ; Re1 represents halogen, a
haloalkyl group containing 1 to 6 carbon atoms, a haloalkoxy group having 1 to 6 carbon atoms, Re5S(O)in- or --SFi5; Re2 represents halogen or hydrogen; Re3 represents hydrogen or Re6S(O)im-; Re4 denotes halogen; Re5 and Re6 represent alkyl containing 1 to 6 carbon atoms, or haloalkyl having 1 to 6 carbon atoms; and m and n are 0, 1 or 2; which are valuable pesticidal intermediates, whereby the preparation process comprises: a) reacting the compound of the general

formula V with the compound of the general formula VI to obtain the
compound of the general formula IV; b) reacting of the obtained compound of the general formula IV with chlorinating or brominating agent to obtain a
corresponding compound of the general formula II; and c) reacting the obtained compound of the general formula II with a cyanide salt. There are further described novel intermediates of the general formulae II and IV. 主权项：
