The process for preparing alkenyl-substituted bis(oxime ether) derivatives of the formula I
where:
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 and
X 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.
制备式I的烯基取代的双(肟醚)衍生物的过程如下:
其中,R1为未取代的C1-C4烷基或C2-C4烯基、C2-C4炔基或苯基取代的甲基;
R2、R4独立地为氢或甲基;
R3、R5独立地为氢或C1-C4烷基、三氟甲基或苯基;
X为—C(═CHCH3)—COOCH3,—C(═CHOCH3)—COOCH3,—C(═NOCH3)—COOCH3,—C(═NOCH3)—CONHCH3或—N(OCH3)—COOCH3。
并描述了通过该过程获得的中间体。式I的烯基取代的双(肟醚)衍生物在文献中被描述为有趣的农作物保护剂。
