摘要

2-[Pyrazolyl- and triazolyl-3'-oxymethylene]phenylisoxazolones, -triazolones and -tetrazolones of formula I where: X is a group A, B or C, where # denotes the bond with the phenyl ring, R^a is hydrogen, halogen, alkyl or alkoxy, R^b is alkyl; Y is N or CR^c, where R^c is hydrogen, halogen or alkyl; n is 0, 1, 2, 3 or 4, where the substituents R¹ may be different if n is greater than 1; R¹ is nitro, cyano, halogen, alkyl with or without substitution or alkoxy with or without substitution or is additionally, if n is 2, an optionally substituted 3 or 4 membered bridge which forms together with the ring to which it is attached a bicyclic partially unsaturated or aromatic radical; R² is hydrogen, nitro, cyano, halogen, alkyl, haloalkyl, alkoxy, alkylthio or alkoxycarbonyl; R³ is optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted aryl or optionally substituted hetaryl, their preparation and their use for controlling unwanted animal pests or harmful fungi.
