Compounds of formula (I) wherein the substituents are as defined in claim 1, are suitable for use as herbicides. Also claimed is a process for the preparation of compounds of the formula I, wherein m is 2 and n is 1, and the other substituents are defined as in claim 1, formula (Ia) by reacting a compound of the formula Ia in a single step or stepwise in succession with compounds of the formula R5-X and/or R6-X, wherein R5 and R6 are as defined in claim 1, and X is a leaving group, and a process for the preparation of compounds of the formula I, wherein R6 is C1-C10alkyl or halogen, m is 2 and n is 1, and the other substituents are defined as in claim 1, formula (Ib) by reacting a compound of the formula 1b with a compound of the formula R5-X, wherein R5 is as defined in claim 1, and X is a leaving group, and a process for the preparation of compounds of the formula I, wherein R5 is chlorine, bromine or iodine, m is 1 or 2, and n is 1, and the other substituents are defined as in claim 1, formula (Ic) by reacting a compound of the formula le with an N- halosuccinimide and an oxidising agent.
式(I)中的化合物,其中取代基如权利要求1所定义,适用作为除草剂。还声明了一种制备式I的化合物的方法,其中m为2,n为1,其他取代基如权利要求1所定义,通过将式Ia的化合物与式R5-X和/或R6-X的化合物在单步或连续逐步反应,其中R5和R6如权利要求1所定义,X为脱离基,制备式(Ia)的方法,并声明了一种制备式I的化合物的方法,其中R6为C1-C10烷基或卤素,m为2,n为1,其他取代基如权利要求1所定义,通过将式1b的化合物与式R5-X的化合物反应,其中R5如权利要求1所定义,X为脱离基,制备式(Ib)的方法,并声明了一种制备式I的化合物的方法,其中R5为氯、溴或碘,m为1或2,n为1,其他取代基如权利要求1所定义,通过将式le的化合物与N-卤代琥珀酰亚胺和氧化剂反应,制备式(Ic)的方法。
