Abstract: The present invention relates to a method for the production of trion-bis(oxime ether) derivatives of formula (I), wherein the substituents have the following meaning: R1, R3 represent unsubstituted, partially or totally halogenated C1-C6-alkyl or C3-C6-cycloalkyl; R2, R4 represent C1-C4-alkyl or a methyl substituted by C2-C4-alkenyl, C2-C4-alkinyl or phenyl and X represents oxygen or N-OH. The invention also relates to the intermediate products obtained with said method.

Abstract: PCT No. PCT/EP95/04463 Sec. 371 Date May 6, 1997 Sec. 102(e) Date May 6, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/16023 PCT Pub. Date May 30, 1996Halomethylbenzoyl cyanides I PH-CO-CN (I) where Ph is phenyl which is substituted by chloromethyl or bromomethyl and may cary 1-4 other rradicals, are prepared from halomethylbenzoyl chlorides II PH-CO-Cl (II), by reacting II with a cyanide-donating compound in the presence of a Lewis acid, if required in an inert organic solvent or diluent, and then isolating the product. The halomethylbenzoyl cyanides I are important intermediates for synthesizing crop protection agents.
