[EN] Compounds of formula (I) wherein the substituents are defined as in claim 1, are suitable for use as herbicides. Also claimed is the intermediate (II) wherein R1 is chloro, R2 is hydrogen and XA is methylsulfonate, three processes for the preparation of compounds of formula (Ih)wherein m is 1 or 2, and the other substituents are defined as in claim 1, and a process for the preparation of compounds of the formula (IVa) wherein XB is a halogen atom, and the substitutents are defined as in claim 1. [FR] L'invention concerne des composés de formule (I) dans laquelle les substituants sont définis comme dans la revendication 1, ces composés étant utilisables comme herbicides. L'invention concerne également des composés de formule intermédiaire (II), dans laquelle R1 représente chloro, R2 représente hydrogène et XA représente méthylsulfonate. L'invention concerne en outre trois procédés pour la préparation de composés de formule (Ih) dans laquelle m vaut 1 ou 2 et les autres substituants sont définis comme dans la revendication 1, ainsi qu'un procédé pour la préparation de composés de formule (IVa) dans laquelle XB est un atome d'halogène et les substituants sont définis comme dans la revendication 1.
