    Abstract: A process for preparing a 1-substituted 5- and/or 3-hydroxypyrazole of the formulae I and II, respectively in which R1 is C1 -C6 -alkyl, C2 -C6 -alkenyl, C2 -C6 -alkynyl, C3 -C6 -cycloalkyl or C1 -C4 -alkoxy. 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. An alkyl vinyl of formula V, reacts with phosgene VIa, "diphosgene" VIb or "triphosgene" VIc, producing an acyl chloride of the formula VII. The alkyl vinyl R2 is C1 -C6 -alkyl or C3 -C6 -cycloalkyl. The acyl chloride is converted by the elimination of hydrogen chloride into 3-alkoxyacryloyl chloride of the formula VIII. Esterifying the 3-alkoxyacryloyl chloride with an alcohol of formula IX, in which R3 is C1 -C6 -alkyl or C3 -C6 -cycloalkyl. This results in the alkyl 3-alkoxyacrylate of the formula III, Reacting the alkyl 3-alkoxyacrylate with a hydrazine of the formula IV, where R1 is defined above a)at a pH of 6-11 to give 5-hydroxypyrazoles of the formula I or b) b) at a pH of 11-14 to give 3-hydroxypyrazoles of the formula II. A 1-substituted 5- and/or 3-hydroxypyrazole of the formulae I and II produced from the above stated process.
