Detailed description of the invention
Definitions and general terms
Reference will now be made in detail to certain embodiments of the invention, examples of which are illustrated in the accompanying structural and chemical formulas. The invention is intended to cover all alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims. Those skilled in the art will recognize that many methods and materials similar or equivalent to those described herein can be used in the practice of the present invention. The present invention is in no way limited to the methods and materials described herein. In the event of one or more of the incorporated references, patents and similar materials differing from or contradictory to the present application (including but not limited to defined terms, term application, described techniques, etc.), the present application controls.
It should further be appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
The following definitions as used herein should be applied unless otherwise indicated. For the purposes of the present invention, chemical elements are in accordance with CAS version of the periodic Table of the elements, and handbook of chemistry and physics, 75 th edition, 1994. In addition, general principles of organic chemistry may be referenced to the descriptions in "Organic Chemistry", thomas Sorrell, university Science Books, sausalato:1999, and "March's Advanced Organic Chemistry" by Michael b.smith and Jerry March, john Wiley & Sons, new york:2007, the entire contents of which are incorporated herein by reference.
The articles "a," "an," and "the" are intended to include "at least one" or "one or more" unless the context clearly dictates otherwise or otherwise. Thus, as used herein, these articles refer to one or to more than one (i.e., to at least one) object. For example, "a component" refers to one or more components, i.e., more than one component is contemplated as being employed or used in embodiments of the described embodiments.
The term "comprising" is an open-ended expression, i.e., including what is indicated by the invention, but not excluding other aspects.
"stereoisomers" refer to compounds having the same chemical structure but different arrangements of atoms or groups in space. Stereoisomers include enantiomers, diastereomers, conformational isomers (rotamers), geometric isomers (cis/trans), atropisomers, and the like.
"enantiomer" refers to two isomers of a compound that do not overlap but are in mirror image relationship to each other.
"diastereoisomers" refers to stereoisomers which have two or more chiralities and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting point, boiling point, spectral properties, and reactivity. The diastereomeric mixture may be separated by high resolution analytical procedures such as electrophoresis and chromatography, e.g., HPLC.
The stereochemical definitions and rules used in the present invention generally follow S.P. Parker, ed., mcGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, new York; and Eliel, e.and Wilen, s., "Stereochemistry of Organic Compounds", john Wiley & Sons, inc., new York, 1994.
Many organic compounds exist in optically active form, i.e., they have the ability to rotate the plane of plane polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to represent the absolute configuration of the molecule with respect to one or more of its chiral centers. The prefixes d and l or (+) and (-) are symbols for specifying the rotation of plane polarized light by a compound, where (-) or l indicates that the compound is left-handed. The compound prefixed with (+) or d is dextrorotatory. One particular stereoisomer is an enantiomer, and a mixture of such isomers is referred to as an enantiomeric mixture. A50:50 mixture of enantiomers is referred to as a racemic mixture or racemate, which can occur when there is no stereoselectivity or stereospecificity in a chemical reaction or process.
The term "tautomer" or "tautomeric form" refers to structural isomers having different energies that can be interconverted by a low energy barrier (low energy barrier). If tautomerism is possible (e.g., in solution), chemical equilibrium of the tautomers can be achieved. For example, proton tautomers (also known as proton transfer tautomers (prototropic tautomer)) include interconversions by proton transfer, such as keto-enol isomerisation and imine-enamine isomerisation. Valence tautomers (valance tautomers) include interconversions by recombination of some of the bond-forming electrons. Specific examples of keto-enol tautomerism are tautomerism of pentane-2, 4-dione, hexane-1, 3-dione and 4-hydroxypent-3-en-2-one tautomer. Another example of tautomerism is phenol-ketone tautomerism. One specific example of phenol-ketone tautomerism is the interconversion of pyridin-4-ol and pyridin-4 (1H) -one tautomers. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
In the present invention, depending on external conditions (such as solvent, pH, etc.), there may be a tautomerism of keto-enol:

It is to be understood that the term "optionally substituted" may be used interchangeably with the term "substituted or unsubstituted". In general, the term "substituted" means that one or more hydrogen atoms in a given structure are replaced with a specific substituent. An optional substituent group may be substituted at each substitutable position of the group unless otherwise indicated. When more than one position in a given formula can be substituted with one or more substituents selected from a particular group, then the substituents may be the same or different at each position.

Compositions and formulations of the compounds of the invention
The compounds of the present invention are generally useful as herbicide active ingredients in compositions or formulations having at least one additional component selected from the group consisting of surfactants, solid diluents, liquid diluents, and the like, which meet the pesticide use requirements, are within the scope of the present invention. The formulation or composition ingredients are selected to be compatible with the physical characteristics of the active ingredient, the mode of application, and environmental factors such as soil type, humidity and temperature.
Useful formulations include liquid compositions and solid compositions. Liquid compositions include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions), and the like, which may optionally be thickened to a gel. General types of aqueous liquid compositions are soluble concentrates, suspension concentrates, capsule suspensions, concentrated emulsions, microemulsions and suspoemulsions. The general types of non-aqueous liquid compositions are emulsifiable concentrates, microemulsifiable concentrates, dispersible concentrates and oil dispersions.
The general types of solid compositions are powders, granules, pellets, lozenges, tablets, filled films (including seed coatings), and the like, which may be water dispersible ("wettable") or water soluble. Films and coatings formed from film-forming solutions or flowable suspensions are particularly useful for seed treatment. The active ingredient may be (micro) encapsulated and further form a suspension or solid formulation; alternatively, the entire active ingredient formulation may be encapsulated (or "coated"). Encapsulation can control or delay the release of the active ingredient. Emulsifiable granules combine the advantages of both emulsifiable concentrate formulations and dry granule formulations. The high concentration compositions are mainly used as intermediates for other formulations.
Sprayable formulations are typically dispersed in a suitable medium prior to spraying. Such liquid and solid formulations are formulated as formulations that are readily diluted in a spray medium (typically water). The spray volume may be in the range of about one to several thousand litres per hectare, but more typically in the range of about ten to several hundred litres per hectare. The sprayable formulation may be mixed with water or another suitable medium in a sink for treatment of the foliage by air or ground application or into the growing medium of the plant. The liquid and dry formulations may be dosed directly into the drip irrigation system or into the furrow during planting.
The formulation will typically comprise an effective amount of the active ingredient, diluent and surfactant, the sum being 100% by weight.
Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, gypsum, cellulose, titanium dioxide, zinc oxide, starch, dextrin, sugar (e.g., lactose, sucrose), silica, talc, mica, diatomaceous earth, urea, calcium carbonate, sodium carbonate and sodium bicarbonate, and sodium sulfate.

The compounds of the invention and any other active ingredients are typically incorporated into the compositions of the invention by dissolving the active ingredient in a solvent or by grinding the active ingredient in a liquid diluent or in a dry diluent. Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. If the solvent used as the liquid composition of the emulsifiable concentrate is water-immiscible, an emulsifier is typically added to emulsify the solvent containing the active ingredient upon dilution with water. A media mill may be used to wet grind an active ingredient slurry having a particle size of up to 2,000 μm to obtain particles having an average diameter of less than 3 μm. The aqueous slurry may be prepared as a finished suspension concentrate (see, e.g., U.S.3,060,084) or further processed by spray drying to form water-dispersible granules. Dry formulations typically require a dry milling step that produces an average particle size in the range of 2 μm to 10 μm. Powders and powders may be prepared by mixing, and typically by grinding (e.g., with a hammer mill or fluid energy mill). Granules and pellets can be prepared by spraying the active material onto preformed particulate carriers or by agglomeration techniques.
