/ ABSTRACT OF THE DISCLOSURE The invention relates to an aryl cyclopropyl-oxirane of the formula IV (IV) in which Ar represents phenyl which is optionally substituted by at least one member selected from the group consisting of halogen; alkyl, alkoxy and alkylthio, each having 1 to 4 carbon atoms; halogenoalkyl, halogenoalkoxy and halogenoalkylthio, each having 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms; and phenyl or phenoxy, each of which is optionally substituted by alkyl having 1 or 2 carbon atoms or halogen; or represents naphthyl or a 5-membered or 6-membered heteroaromatic which is optionally substituted by the abovementioned phenyl substituents and contains 1 or 2 heteroatoms of nitrogen, oxygen or sulphur, R2 represents fluorine, chlorine, bromine, cyano, thio-cyano, alkylcarbonyloxy having 1 to 4 carbons atoms in the alkyl part, alkylcarbonylthio having 1 to 4 carbon atoms in the alkyl part, or the groupings -X-R3 and -NR4R5, R3 represents alkyl having 1 to 18 carbon atoms, cycloalkyl having 3 to 8 carbon atoms, alkenyl having 2 to 18 carbon atoms, alkinyl having 2 to 18 carbon atoms, hydroxyalkyl having 1 to 18 carbon atoms, alkylthioalkyl having 1 to 6 carbon atoms in the alkylthio part and 1 to 6 carbon atoms in the alkyl part, carboxyalkyl having 1 to 18 carbon atoms in the alkyl part, alkoxycarbonylalkyl having 1 to 6 carbon atoms in the alkoxy part and 1 to 6 carbon atoms in the alkyl part, or phenyl or phenyl-alkyl having 1 or 2 carbon atoms in the alkyl part, each of which is optionally substituted by the abovementioned phenyl substituents for Ar, or R3 represents the radical of the formula R4 and R5 independently of one another represent hydrogen or alkyl having 1 to 4 carbon atoms, or R4 and R5, together with the nitrogen atom to which they are bonded, represent a 5-membered or 6-membered ring which is optionally substituted by alkyl having 1 to 4 carbon atoms or alkylcarbonyl having 1 to 4 carbon atoms in the alkyl part, and may contain 1 or 2 further heteroatoms of oxygen, sulphur or nitrogen, or R2 furthermore represents hydrogen when Ar represents an optionally substituted 5-membered or 6-membered heteroaromatic ring, X represents oxygen, sulphur, an SO group or an SO2 group and to processes for the preparation thereof. The compounds are useful as intermediates in the preparation of fungicidal and plant growth regulating compounds. |
