Verfahren zur Herstellung von Hydroxyarenen

摘要

The invention relates to a novel process for producing hydroxyarenes of general formula (I) in which n is a number 1, 2, 3, or 4, R is cyano, carboxy, formyl, nitro, halogen or possibly substituted alkyl, alkoxy, alkylthio, alkyl sulphinyl, alkyl sulphonyl, alkyl carbonyl or alkoxy carbonyl and Z is hydrogen, cyano, nitro, halogen, alkyl, alkyl halide or possibly substituted monocyclic or bicyclic, saturated or unsaturated heterocyclyl, heterocyclyl amino or heterocyclyl imino, in which halogen arenes of general formula (II) in which n, R and Z have the above meanings and X is halogen, are reacted with 3-hydr xy propionitrile of formula (III) HO-CH2CH2-CN, possibly in the presence of a reaction promoter and a diluent at temperatures between 0 and 100 DEG C.
