    Abstract: Naphthyl ethers of the formula I in which the index and the substituents have the following meaning: A is optionally substituted phenyl or optionally substituted 5- to 6-membered heteroaryl which, in addition to carbon ring members, can contain one to three nitrogen atoms or one or two nitrogen atoms and an oxygen or sulphur atom or an oxygen or sulphur atom as further ring members; n is 0 or 1; X is oxygen, sulphur or nitrogen, the nitrogen atom carrying one of the following radicals: hydrogen, C1-C4-alkyl, C1-C4-alkoxy, C3-C6-cycloalkyl, optionally substituted phenyl or optionally substituted benzyl; Y is oxygen or in the case where Z is NOCH3: oxygen or nitrogen, where the nitrogen atom carries one of the following radicals: hydrogen, C1-C4-alkyl or C1-C4-alkoxy; Z is CHOCH3, NOCH3, CHCH3 or CHCH2CH3; R is C1-C4-alkyl; R is optionally substituted C1-C6-alkyl, C3-C6-cycloalkyl, C2-C6-alkenyl or C3-C6-alkynyl; optionally substituted phenyl; optionally substituted 5- or 6-membered heteroaryl containing, in addition to carbon ring members, one to three nitrogen atoms or one or two nitrogen atoms and an oxygen or sulphur atom as further ring members; or in the case where the value of n is 0 additionally to the above meanings: halogen, C1-C6-alkoxy, C1-C4-alkylsulphoxyl or phenylsulphoxyl, where the phenyl ring can in turn carry substituents, process for the preparation of the naphthyl ethers I, compositions containing them and their use for the control of animal pests or harmful fungi.

    Abstract: The prepn. of 1-(Hetero)aryl-3-hydroxy-pyrazoles of formula (I) comprises mixing propiolic acid esters of formula R1C IDENTICAL CCOOR' (II) with (hetero)arylhydrazine derivs. of formula RNHNH2 (III) in an inert solvent; and then treating with a base at 0-60 degrees C. R = opt. substd. aromatic or heteroaromatic; n = 0, 1 or 2; R1 = a gp. which is stable under the reaction conditions; R' = alkyl, cycloalkyl or aryl.
