    Abstract: In order to prepare hydroxylamino-ethers having formula (I), in which X stan ds for NO2, CN. halogen. alkyl and halogen alkyl: Y stands for H, NO2. CN, halogen, alkyl and halogen alkyl: n equals 0 to 2 or 1 w 4 when Y and all X's sand for halogen: alk stands for possibly substituted alkylene, as well as their salts with mineral acids or strong organic acids, either a hydroxyimino compound having formula (II) in which R1 stands for alkyl, R2 stands for alkyl, alkoxy or R1 + R2 stand for an alkylene chain, is reacted in the presence of an alkali metal hydroxide, alkali metal alcoholate, alkali metal hydrogen carbonate or alkali metal carbonate as bases, or the corresponding anion of (II) is directly reacted with an alkylating agent having formula (III], in which R3 stands for possibly substituted alkyl or phenyl. so that an oximino derivate having formula (IV) is produced. The oximino derivative (IV) is split by a mineral acid or a strong organic acid into a salt of (I), and if desired the latter is converged into the fre e compound (I) by means of a base. The hydroxylamino-ethers (I) constitute intermediate products for plant protecting and pharmaceutical agents.

    Abstract: The invention relates to a process for preparing 1-substituted 5- and/or 3-hydroxypyrazoles of the formulae I and IIin which R1 is C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, C3-C6-cycloalkyl or C1-C4-alkoxy, where these groups may be substituted by halogen, C1-C4-alkoxy, phenoxy, C1-C6-alkoxycarbonyl, C1-C6-alkylthiocarbonyl or by a cyclic ring system having 3-14 ring atoms, which comprises reactingan alkyl 3-alkoxyacrylate of the formula IIIin which R2, R3 independently of one another are C1-C6-alkyl or C3-C6-cycloalkyl with a hydrazine of the formula IVin which R1 is as defined abovea) at a pH of 6-11 to give 5-hydroxypyrazoles of the formula I orb) at a pH of 11-14 to give 3-hydroxypyrazoles of the formula II.

    Abstract: The invention relates to a method for producing 2-{1-[2-(4-chlorophenoxy)-propoxyimino]-butyl}-3-hydroxy-5-(tetrahydro thiopyrane-3-yl)-cyclohex-2-enone lithium salt by reacting the corresponding acid 2-{1-[2-(4-chlorophenoxy)-propoxyimino]-butyl}-3-hydroxy-5-(tetrahydro thiopyrane-3-yl)-cyclohex-2-enone with lithium hydroxide, and for extracting the lithium salt. It is advantageous to use a solvent mixture containing methanol and at least one aromatic hydrocarbon, and to remove part of the solvent before extraction. It is especially preferable to dissolve the acid in an aromatic hydrocarbon, preferably toluol, and to use a methanolic lithium hydroxide solution. The product obtained efficiently according to the inventive method also has considerable advantages in terms of formulation techniques.
