    Abstract: In the present invention there is disclosed a process for preparing of alpha-bis-oxime isomers of the general formula Ia: Re1O-N=CRe2-CRe3=N-ORe4 (Ia), wherein the groups Re1O- and Re2 on the N=C bond are in mutual position cis and wherein Re1 represents alkyl containing 1 to 6 carbon atoms, alkenyl containing 3 to 6 carbon atoms and alkynyl having 3 to 6 carbon atoms, Re2 represents an optionally substituted phenyl or an optionally substituted hetaryl, Re3 represents a hydrogen atom, a cyano group, a halogen atom, alkyl containing 1 to 4 carbon atoms, haloalkyl containing 1 to 4 carbon atoms and cycloalkyl having 3 to 6 carbon atoms and Re4 represents hydrogen. The proposed preparation process is characterized in that {alpha}-bis-oxime isomer of the general formula Ib: Re1O-N=CRe2-CRe3=N-ORe4 (Ib), wherein the groups Re1O- and Re2 on the N=C bond are in mutual position trans and wherein Re1, Re2, Re3 and Re4 are as specified above, optionally in a mixture with the {alpha}-bis-oxime isomer of the general formula Ia: Re1O-N=CRe2-CRe3=N-ORe4 (Ia) is treated in an aromatic hydrocarbon with a Lewis acid.
