    Abstract: The invention relates to a method for the preparation ofconsiderably pure isomers of -bis-oximes having the formulaR10-N=CR2-CR3=N-Or4ciswhere groups R10- and R2 in the N=C- bond are found incis-position towards each other and the residues in them have thefollowing meanings: R1 & R4 mean hydrogen or C-organic residue, R2is hydrogen, cyano, nitro, hydroxy, amino, halogen or organicresidue which can be bound directly or by oxygen, sulphur ornitrogen atom to the carbon chain, R3 is hydrogen, cyano, nitro,hydroxy, amino, halogen, alkyl, halogenalkyl, alkoxy,halogenalkoxy, alkylthio, alkylamino, dialkylamino or cycloalkyl.The compounds are produced form a mixture of the isomers of-bis-oximes with formula Ia and with formulaR10-N=CR2-CR3=N-OR4transwhich is treated in organic solvent with Lewis acid.12 claims
