The invention provides cyclohexanone derivatives of the general formula
in which n represents an integer from 0 to 5; each R represents a halogen atom, nitro, cyano, hydroxyl, alkyl, haloalkyl, alkoxy, haloalkoxy, amino, alkylamino, dialkylamino, alkoxycarbonyl, carboxyl, alkanoyl, alkylthio, alkylsulphinyl, alkylsulphonyl, carbamoyl, alkylamido, cycloalkyl or phenyl group; R1, R2 and R3 independently represent a hydrogen atom or an alkyl group; R6 and R7 together represent a single carbon-carbon bond or an epoxy group; and R8 represents a hydrogen atom or a hydroxyl group; with the proviso that when R6 and R7 together represent an epoxy group then R8 represents a hydrogen atom; and a process for their preparation. Compounds of formula I are useful as intermediates in the preparation of certain fungicidally active cyclopentane derivatives.
