Abstract

Abstract Oxirane compounds of the formula <IMAGE> (II) in which R represents tert-butyl, iso-propyl radical, cyclopropyl, substituted cyclopropyl, cyclopentyl or substituted cyclopentyl, cyclohexyl or substituted cyclohexyl, in each case the substituent being selected from methyl, or phenyl which is optionally mono or di-substituted by identical or different substituents selected from fluorine, chlorine, methyl and trifluoromethyl, Y represents a grouping -OCH2-, each Z is individually selected from the group consisting of a fluorine, chlorine or bromine atom, methyl, tert-butyl, cyclohexyl, methoxy, methylthio, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, phenyl, phenoxy, benzyl and benzyloxy, said phenyl, phenoxy, benzyl and benzyloxy being optionally mono or di-substituted by identical or different substituents selected from fluorine, chlorine and methyl, m is 0, 1, 2 or 3; these compounds are particularly useful as intermediates for compounds used in agricultural compositions as plant growth regulants.
