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.
该过程用于制备式I的烯基取代的双(肟醚)衍生物,其中:R1是未取代的C1-C4-烷基或C2-C4-烯基,C2-C4-炔基或苯基取代的甲基;R2,R4彼此独立地是氢或甲基;R3,R5彼此独立地是氢或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。文献中描述了式I的烯基取代的双(肟醚)衍生物作为有趣的农作物保护剂。
