摘要：
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 Ib 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 1e with an N-halosuccinimide and an oxidising agent.
