Abstract

Pyrimidyl phenyl and pyrimidyl benzyl ethers of the general formula I ##STR1## and their salts and N-oxides, where the substituents and indices have the following meanings: PA1 Q is (CO.sub.2 CH.sub.3).dbd.CHCH.sub.3, C(CO.sub.2 CH.sub.3).dbd.CHOCH.sub.3, C(CONHCH.sub.3).dbd.CHOCH.sub.3, C(CONH.sub.2).dbd.NOCH.sub.3, C(CONHCH.sub.3).dbd.NOCH.sub.3 or N(OCH.sub.3)--CO.sub.2 CH.sub.3 ; PA1 n is 0 or 1; PA1 R.sup.1 is hydrogen or an organic radical bonded via a carbon atom; PA1 R.sup.2 is hydrogen, cyano, halogen or an organic radical bonded via a carbon, oxygen, sulfur or nitrogen atom; PA1 R.sup.3 is hydrogen, halogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.2 -haloalkyl; PA1 R.sup.4 is hydrogen, cyano, nitro, halogen or an organic radical bonded via a carbon, oxygen, sulfur or nitrogen atom; PA1 y is 0, 1, 2 or 3, it being possible for the radicals R.sup.5 to be different if y is 2 or 3; PA1 R.sup.5 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, processes and intermediates for their preparation, and their use.
