Abstract
Abstract The invention relates to compounds of formula I (wherein having a total of no more than nine carbon atoms; n is 0 or 1; R, is H, F, Cl, Br, NO 2 , CF 3 , C,-C 3 alkyl, OCF 3 or C 1 -C 4 alkoxy; R 2 and R 3 are selected independently from H and CH 3 ; R 4 is H, C 1 -C 3 alkyl, F, Cl, Br, CF 3 , OCF 3 or C 1 -C 3 alkoxy; R 5 is CH 3 , Cl, Br or H; A is X is H, CH 3 , OCH 3 , OCH 2 CH 3 , OCH 2 CF 3 , CH 2 OCH 3 or Cl; Y is CH 3 , OCH 3 or OCH 2 CH 3 ; Z is N, CH, CCI, C-Br, C-CN, CCH 3 , C-CH 2 CH 3 , C-CH 2 CH 2 CI or C-CH 2 CH=CH 2 ; Y' is H, CH 3 , OCH 3 or Cl; and Q is CH 2 or 0) and salts thereof. These compounds have been found to posess herbicidal activity and the invention further relates to compositions containing them and to a method for their use in controlling the growth of undesired vegetation.
