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, NO2, CF3, C,-C3 alkyl, OCF3 or C1-C4 alkoxy;
R2 and R3 are selected independently from H and CH3;
R4 is H, C1-C3 alkyl, F, Cl, Br, CF3, OCF3 or C1-C3 alkoxy;
R5 is CH3, Cl, Br or H;
A is
X is H, CH3, OCH3, OCH2CH3, OCH2CF3, CH2OCH3 or Cl;
Y is CH3, OCH3 or OCH2CH3;
Z is N, CH, CCI, C-Br, C-CN, CCH3, C-CH2CH3, C-CH2CH2CI or C-CH2CH=CH2;
Y' is H, CH3, OCH3 or Cl; and
Q is CH2 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.
