Date Oct. 17, 1996A process for the preparation of largely isomerically pure alpha -bisoximes of the formula IaR1O-N=CR2-CR3=N-OR4Iawhere the groups R1O- and R2 on the N=C bond are cis to one another and where the radicals have the following meanings: R1 and R4 are hydrogen or a C-organic radical; R2 is hydrogen, cyano, nitro, hydroxyl, amino, halogen or an organic radical which can be bonded to the structure directly or via an oxygen, sulfur or nitrogen atom; R3 is hydrogen, cyano, nitro, hydroxyl, amino, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, alkylamino, dialkylamino or cycloalkyl, from a mixture of the isomers of the a-bisoximes Ia and Ib is described.
