Abstract:
A diphenyl ether of the formula I, ##STR29## or a salt or N-oxide thereof where the substituents and the indices have the following meanings:Q is C(CONH.sub.2).dbd.CHOCH.sub.3, C(CO.sub.2 CH.sub.3).dbd.NOCH.sub.3, C(CONHCH.sub.3).dbd.NOCH.sub.3 or N(OCH.sub.3)--CO.sub.2 CH.sub.3 ;n is 0 or 1;R.sup.1 is hydrogen or one of the following groups: unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl or heteroaryl;R.sup.2 is hydrogen or one of the following groups: unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl or heteroaryl, it being possible for these groups to be linked to the skeleton directly (via a carbon atom) or via an oxygen, sulfur or nitrogen atom;x is 0, 1 or 2, it being possible for the radicals R.sup.3 to be different if x is 2;R.sup.3 is cyano, nitro, halogen or one of the following groups: unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclyl, aryl or heteroaryl, it being possible for these groups to be linked to the skeleton directly (via a carbon atom) or via an oxygen, sulfur or nitrogen atom orR.sup.2 and a substituent R.sup.3 which is adjacent to the group O.sub.n --C(R.sup.2).dbd.NOR.sup.1 is C.sub.2 -C.sub.3 -alkylene which can be interrupted by an oxygen or sulfur atom or can be linked to the phenyl ring via an oxygen or sulfur atom;y is 0, 1, 2 or 3, it being possible for the radicals R.sup.4 to be different if y is 2 or 3;R.sup.4 is cyano, halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl or C.sub.1 -C.sub.4 -alkoxy.
