Abstract

The present invention relates to compounds of Formula (I), or an agronomically acceptable salt of said compounds wherein Q, R 1 , R 3 , R 4 and n are as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I) and to the use of compounds of Formula (I) for controlling weeds, in particular in crops of useful plants.

Claims (353)

1 . A compound of Formula (I):

or an agronomically acceptable salt thereof,

wherein

Q is a 5-membered aromatic heterocyclic ring selected from the group consisting of:

wherein R 2 is selected from the group consisting of hydrogen, C 1 -C 4 alkyl, C 2 -C 4 alkenyl, C 2 -C 4 alkynyl, cyclopropyl, C 1 -C 2 haloalkyl, C 1 -C 2 alkoxy-, C 1 -C 2 haloalkoxy-, halogen, —C(O)C 1 -C 4 alkyl, NO 2 , —CH 2 CN, —CN and —S(O) p C 1 -C 4 alkyl;

X is O or S(O) p ;

each R 1 is independently selected from the group consisting of halogen, —CN, nitro, C 1 -C 4 alkyl, C 2 -C 4 alkenyl, C 2 -C 4 alkynyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy-, C 1 -C 4 haloalkoxy- and —S(O) p C 1 -C 4 alkyl;

R 4 is selected from the group consisting of hydrogen, halogen, C 1 -C 3 alkyl, C 1 -C 3 haloalkyl and C 2 -C 3 alkenyl;

n=0, 1 or 2; and

p=0, 1 or 2.

2 . The compound of Formula (I) according to claim 1 , wherein Q is selected from the group consisting of Q1, Q2 and Q5.

3 . The compound of Formula (I) according to claim 1 , wherein Q is Q2.

4 . The compound according to claim 1 , wherein n is 1 and R 1 is fluoro.

5 . The compound according to claim 4 , wherein R 1 is 3-fluoro.

6 . The compound according to claim 1 , wherein R 3 is selected from the group consisting of hydrogen, chloro, bromo and difluoromethyl.

7 . The compound according to claim 1 , wherein R 4 is selected from the group consisting of hydrogen, chloro, bromo, methyl, vinyl and difluoromethyl.

8 . A herbicidal composition comprising a compound according to claim 1 and an agriculturally acceptable formulation adjuvant.

9 . A herbicidal composition according to claim 8 , further comprising at least one additional pesticide.

10 . A herbicidal composition according to claim 9 , wherein the additional pesticide is a herbicide.

11 . A method of controlling weeds at a locus comprising application to the locus of a weed controlling amount of a composition according to claim 8 .

12 . A compound selected from Compound 1.001-1.035 according to Formula (I):
