    Abstract: The invention relates to a method for producing substituted hydroxypyrazoles and new intermediate products. It relates in particular to a method for producing compounds of formula (I) in which R1 is hydrogen, an aliphatic gro up with between 1 and 8 carbon atoms, C1-C6-alkoxycarbonyl, C1-C6-alkyl thiocarbonyl or a cyclic ring system with between 3 and 14 ring atoms; R2 is hydrogen, an aliphatic group with between 1 and 8 carbon atoms; or R1 and R2 together with the carbon atom to which they are bound are a cyclic or bicycl ic ring system with between 3 and 14 ring atoms. Said method comprises the production, as starting or intermediate products, of compounds of formula (I I) in which R3 and R4 are readily cleavable groups and R1 and R2 have the meanings given above. Said compounds are cyclized under suitable reaction conditions to yield compounds of formula (I).

Date Nov. 16, 1995Preparation of mixtures of O-phenoxyalkylhydroxylamines Ia and Ib (Ia): H2NOCH2CH(R1)OAr (Ib): H2NOCH(R1)CH2OAr and the corresponding salt mixtures by a) converting mixtures of isomers of O-(2-hydroxyethyl)oximes IIa and IIb (IIa): (III): into a mixture of sulfonates IVa and IVb (IVa): (IVb): b) reacting this mixture of IVa and IVb with a phenol HO-Ar (V) to give a mixture of O-phenoxyalkoximes VIa and VIb (VIa): (VIb): c) hydrolyzing this mixture in the presence of an acid and, if desired d) liberating the O-phenoxyalkylhydroxylamines Ia and Ib from the resulting salts using a mineral acid. Compounds Ia/Ib and VIa/VIb are important intermediates for crop protection agents.
