2-[PYRAZOLYL AND TRIAZOLYL-3'-OXYMETHYLENE]-PHENYL-ISOXAZOLONES, TRIAZOLONES AND TETRAZOLONES AS PESTICIDES AND FUNGICIDES

摘要

The invention relates to 2-¢pyrazolyl and triazolyl-3'-oxymethylene!-phenyl-isoxazolones, triazolones and tetrazolones of formula (I), wherein the indices and the substituents have the following meaning: X represents a group A, B or C, # indicating the bond with the phenyl ring, Ra being hydrogen, halogen, alkyl or alkoxy and Rb being alkyl; Y represents N or CRc, Rc being hydrogen, halogen or alkyl; n represents 0, 1, 2, 3 or 4 and the substituents R1 can be different when n is greater than 1; R1 represents nitro, cyano or halogen, optionally substituted alkyl or optionally substituted alkoxy or if n is 2, additionally an optionally substituted bridge which is bound to two adjacent ring atoms, said bridge containing three to four members from the group of 3 or 4 carbon atoms, 2 to 3 carbon atoms and 1 or 2 nitrogen, oxygen and/or sulphur atoms, and together with the ring to which it is bound may form a partially unsaturated or aromatic radical; R2 represents hydrogen, nitro, cyano, halogen, alkyl, halogenalkyl, alkoxy, alkylthio or alkoxycarbonyl and R3 represents optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted aryl or optionally substituted hetaryl.
