23189-6125D ABSTRACT The invention relates to an aryl cyclopropyl ketone of the formula II Image (II) in which Ar represents phenyl which is optionally substituted by at least one member selected from the group consisting of halogen; alkyl, alkoxy and alkythio, 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 substi- tuted 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 l to 4 carbon 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, cyclo- alkyl 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 l 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, alkoxy- 23189-6125D carbonylalkyl having 1 to 6 carbon atoms in the alkoxy part and 1 to 6 carbon atoms in the alkyl part, or phenyl or phenylalkyl 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 Image , R4 and R5 independently of one another represent hydro- gen 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 R furthermore represents hydrogen when Ar represents an optionally substituted 5-membered or 6-membered heteroaromatic ring, X represents oxygen, sulphur, an SO2 group or an SO group and to process for the preparation thereof. The compounds are useful as intermediates in the preparation of fungicidal and plant growth regulating compounds. of formula (I).
