    Abstract: The process for preparing alkenyl-substituted bis(oxime ether) derivatives of the formula Iwhere:R1 is unsubstituted C1-C4-alkyl or C2-C4-alkenyl-, C2-C4-alkynyl- or phenyl-substituted methyl;R2, R4 independently of one another are hydrogen or methyl;R3, R5 independently of one another are hydrogen or C1-C4-alkyl, trifluoromethyl or phenyl andX is -C(=CHCH3)-COOCH3,-C(=CHOCH3)-COOCH3,-C(=NOCH3)-COOCH3,-C(=NOCH3)-CONHCH3 or-N(OCH3)-COOCH3,and intermediates which are obtainable by this process are described. Alkenyl-substituted bis(oxime ether) derivatives of the formula I are described in the literature as interesting crop protection agents.
