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 thepreparation of compounds of the formula I, wherein m is 2 and n is 1, and theother substituents are defined as in claim 1, formula (Ia) by reacting acompound of the formula Ia in a single step or stepwise in succession withcompounds of the formula R5-X and/or R6-X, wherein R5 and R6 are as defined inclaim 1, and X is a leaving group, and a process for the preparation ofcompounds of the formula I, wherein R6 is C1~-C10alkyl or halogen, m is 2 andn is 1, and the other substituents are defined as in claim 1, formula (Ib) byreacting 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 processfor 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 aredefined as in claim 1, formula (Ic) by reacting a compound of the formula lewith an N- halosuccinimide and an oxidising agent.
