ABSTRACT:
The invention provides cyclohexenol derivatives of the general formula ##STR1## 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; and R.sup.1, R.sup.2 and R.sup.3 independently represent a hydrogen atom or an alkyl group, with the provisos that when R.sup.1, R.sup.2 and R.sup.3 all represent a hydrogen atom then n is not 0 and, when R.sup.1, R.sup.2 and R.sup.3 all represent a hydrogen atom and n is 1, R does not represent a fluorine atom substituted at the 4-position of the phenyl ring; and a process for their preparation. Compounds of formula I are useful as intermediates in the preparation of certain fungicidal active cyclopentane derivatives.
