| 摘要 |
The invention relates to a novel process for producing thereof hydroxyarenes of the general formula (I)in whichn represents the numbers 1, 2, 3 or 4,R represents cyano, carboxyl, formyl, nitro, halogen or represents alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylcarbonyl or alkoxycarbonyl, each of which is optionally substituted, andZ represents hydrogen, cyano, nitro, halogen, alkyl, halogenoalkyl, or represents monocyclic or bicyclic, saturated or unsaturated heterocyclyl, heterocyclylamino or heterocyclylimino, each of which is optionally substituted,characterized in that halogenoarenes of the general formula (II)in whichn, R and Z are each as defined above andX represents halogenare reacted with 3-hydroxy-propionitrile of the formula (III),if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, at temperatures between 0° C. and 100° C.
