Novel herbicides

The invention relates to novel herbicidally active cyclohexanediones of formula I or I' STR1 in which R1 and R2 independently of one another are each hydrogen; halogen; nitro; cyano; C1 -C4 alkyl; C1 -C4 alkoxy; C1 -C4 alkyl-S(O)n --; COR8 ; C1 -C4 haloalkoxy; or C1 -C4 haloalkyl; R3, R4 and R5 independently of one another are each hydrogen; C1 -C4 alkyl; or phenyl or benzyl each unsubstituted or substituted by up to three identical or different substituents from halogen, nitro, cyano, C1 -C4 alkyl, C1 -C4 alkoxy, C1 -C4 alkyl-S(O)n --, C1 -C4 haloalkyl, C1 -C4 haloalkyl-S(O)n -- and C1 -C4 haloalkoxy; R6 is hydrogen; C1 -C4 alkyl, C1 -C4 alkoxycarbonyl; or cyano; R7 is OH; or O? M≈ ; R8 is OH; C1 -C4 alkoxy; NH2 ; C1 -C4 alkylamino; or di-C1 - C4 alkylamino; n is 0, 1 or 2; M+ is a cation equivalent of a metal ion or of an ammonium ion that is unsubstituted or substituted by up to three C1 -C4 alkyl, C1 -C4 hydroxyalkyl or C1 -C4 alkoxy-C1 -C4 alkyl groups, to herbicidal compositions, to processes for the preparation of novel compounds and to novel intermediates and the preparation thereof.
