1-alkyl-3-[1-(substituted phenyl) benzotriazol-6-yl] uracils

Description

BACKGROUND OF THE INVENTION

[0001] Weeds cause tremendous global economic losses by reducing crop yields and lowering crop quality. Worldwide, agronomic crops must compete with hundreds of weed species.

[0002] In spite of the commercial herbicides available today, damage to crops caused by weeds still occurs. Accordingly, there is ongoing research to create more effective and/or more selective herbicidal agents.

[0003] Certain 1-phenylbenzotriazole herbicidal agents are described in U.S. Pat. No. 5,523,277. This patent generically discloses benzotriazoles which are substituted with a Q group which may be one of 22 specified groups. However, only one Q group (Q6) is exemplified in this patent.

[0004] Certain uracil substituted benzotriazole herbicidal agents are described in U.S. Pat. No. 5,661,108. This patent discloses benzotriazoles substituted in the 1-position by hydrogen, straight or branched chain alkyl, alkenyl, hydrozyalkyl, alkoxyalkyl, haloalkyl, alkoxycarbonyl, or arylalkyl. Substitution in the 1-position with (substituted) phenyl is however not disclosed.

[0005] Surprisingly, it has now been found the certain of the compounds generically disclosed in U.S. Pat. No. 5,523,277 are more effective and/or more selective herbicidal compounds wherein Q is Q6.

[0006] It is therefore an object of the present invention to provide compounds which are highly effective for the control of undesirable plant species.

[0007] It is also an object of the present invention to provide methods for the selective control of undesirable plant species in the presence of crops.

[0008] Those and other objects and features of the present invention will become more apparent from the detailed description thereof set forth below.

EXAMPLE 34

Preparation of Methyl {2-[5-Fluoro-6-(3-Methyl-2,6-Dioxo-4-(Trifluoromethyl) -3,6-Dihydro-1(2H)-Pyrimidinyl)-1H-1,2,3H)-Benzotriazol-1-yl]-4-Methylphenoxy}Acetate

[0118]

[0119] 3-[5-fluoro-1-(2-hydroxy-5-methylphenyl)-1H-1,2,3-benzotriazol-6-yl]-1-methyl-6- (trifluoromethyl) -2,4 (1H,3H)-pyrimidinedione (0.5 g, 0.0011 mol) is added to dry dimethylformamide (5 mL) followed by methyl bromoacetate (0.18 g. 0.0012 mol) and potassium carbonate (0.18 g, 0.0013 mol) . After stirring overnight at room temperature, the reaction mixture is poured into water to give, after drying, the title compound as a white solid (0.4 g, 71%, mp 95-98° C.) which is identified by IR, NMR and mass spectral analyses.

EXAMPLE 46

Postemergence Herbicidal Evaluation of Test Compounds

[0121] In this evaluation, seedling plants are grown in jiffy flats for about two weeks. The test compounds are dispersed in 80/20 acetone/water mixtures containing 1.0% SUN-IT® II, a methylated seed oil, in sufficient quantities to provide the equivalent of about 0.006 kg to 0.400 kg per hectare of active compound when applied to the plants through a spray nozzle operating at 40 psi for a predetermined time. After spraying, the plants are placed on greenhouse benches and are cared for in accordance with conventional greenhouse procedures. Approximately two - three weeks after treatment, the seedling plants are examined and rated according to the rating system set forth below. Data obtained are reported in Table I below. Where more than one test is involved for a given compound, the data are averaged.

EXAMPLE 47

Preemergence Herbicidal Evaluation of Test Compounds

[0124] The preemergence herbicidal activity of the test compounds of the present invention is exemplified by the following tests in which the seeds of a variety of monocotyledonous and dicotyledonous plants are separately mixed with potting soil and planted on top of approximately one inch of soil in separate pint cups. After planting, the cups are sprayed with the selected aqueous acetone solution containing test compound in sufficient quantity to provide the equivalent of about 0.013 to 0.800 kg per hectare of test compound per cup. The treated cups are then placed on greenhouse benches, watered and cared for in accordance with conventional greenhouse procedures. From four to five weeks after treatment, the tests are terminated and each cup is examined and rated according to the rating system provided in Example 46. The data obtained are reported in Table II below.
