The present divisional application is divided out of parent application Serial No. 2,189,698, which was itself divided out of application Serial No. 2,027,206, filed on October 10, 1990.
The invention of the parent application relates to new sulphonylaminocarbonyl-triazolinones of the formula I, to several processes for their preparation, and to their use as herbicides.
The invention of divisional application Serial No.
The present divisional application is divided out of parent application Serial No. 2,189,698, which was itself divided out of application Serial No. 2,027,206, filed on October 10, 1990.
The invention of the parent application relates to new sulphonylaminocarbonyl-triazolinones of the formula I, to several processes for their preparation, and to their use as herbicides.
The invention of divisional application Serial No.
2,189,698 relates to novel intermediates of formula IIa and processes for preparing the intermediates. Compounds of the formula IIa are useful in the preparation of compounds of formula I.
The invention of the present divisional application relates to novel intermediates of formula IIa which are structurally different than those of application Serial No. 2,189,698. The intermediates of the present divisional application are useful in the preparation of compounds of formula I, illustrated below.
It is known that certain substituted amino-carbonylimadazolinones, such as, for example, 1-isobutyl-aminocarbonyl-2-imidazolidinone (isocarbamide), have herbicidal properties (cf. R. Wegler, Chemie der Pflanzenschutz-and Schadlingsbekampfungsmittel [Chemistry of Plant Protection Agents and Pesticides], Vol. 5, p. 219, Springer-Verlag, Berlin-Heidelberg-New York, 1977).
However, the action of this compound is not satisfactory in all respects. The new sulphonylaminocarbonyl-triazolinones are a subgroup of the broad class of compounds of the a general formula (T) R SOZ NH CO N N --- R
N----Rz in which R'' represents hydrogen, hydroxyl or amino, or represents an - la -opt ionally subst ituted radical f rom the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, alkoxy, alkenyloxy, alkylamino and dialkylamino, R2 represents hydrogen, hydroxyl, mercapto or amino, or represents an optionally substituted radical from the series comprising alkyl, cycloalkyl, cycloalkenyl, aralkyl, aryl, alkoxy, alkylamino and dialkylamino, and R3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, as well as salts of compounds of the formula (I), have now been found.
The sulphonylaminocarbonyl-triazolinones of the general formula (I) are obtained when a) triazolinones of the general formula (II) O
HN- 'N-R~
N (ll) in which R1 and R2 have the abovementioned meanings, are reacted with sulphonyl isocyanates of the general formula (III) R3 802-N C-~ (III) in which 2Q R3 has the abovementioned meanings, if appropriate in the presence of a diluent, or when b) triazolinone derivatives of the general formula (IV) Z-CO-N~N-R1 (IV) ~R2 in which R' and R2 have the abovementioned meanings and Z represents halogen, alkoxy, aralkoxy or aryloxy, axe reacted with sulphonamides of the general formula (V) R3'S~2'NH2 (V) in which R3 has the abovementioned meaning, if appropriate in the presence of an acid acceptor and if appropriate in the presence of a diluent, or when c) triazoli.t~ones of the general formala (II) O

in which R1 and RZ have the abovementianed meanings are reacted with sulphonamide derivatives of the general _ formula (VI) R3-S02-NH-CO-Z (~z) i. n wh 1 ch R3 has the abovementioned meaning and Z represents halogen, alkoxy, aralkoxy or aryloxy, if appropriate in the presence of an acid acceptor and if appropriate in the presence of a diluent, and, if appropriate, salts are formed by customary methods from ZO the compounds of the formula (T) prepared by process (a), (b) or (c).
The new sulphonylaminocarbonyl-tria2olinones of the general formula (I) and their salts are distinguished by a powerful herbicidal activity. Surprisingly, the new compounds of the formula (I) show a considerably better herbicidal action than the known herbicide 1-isobutyl-aminocarbonyl-2-imidazolidinone (isocarbamide), which has a similar structure.

In formula (VI), R3 and Z preferably, or in particular, have those meanings which have already been ment ioned above in connect ion with 'the descript ion of the _ 47 compounds of the formula (I) or (IV) as being preferred, or particularly preferred, for R3 and Z.
Process (c) is preferably carried out using diluents. Suitable diluents in this context are the same organic solvents as have been mentioned above in connection with the description of process (a).
If appropriate, process (c) is carried out in the presence of an acid acceptor. Suitable acid-binding agents in this context are the same as have been mentioned above in connection with the description of process (b).
When carrying out process (c) the reaction temperatures can be varied within a substantial range. In general, the process is carried out at temperatures between 0°C and 100°C, preferably at temperatures between 10°C
and 60°C.
In general, process (c) is carried out under atmospheric pressure. However, it is also possible to carry out the process under increased or reduced pressure.
for carrying out process (c), the specifically required starting substances are generally employed in approximately equimolar amounts. However, it is also possible to use one of the two specifically employed components in a substantial excess.. In general, the reactions' are carried out in a suitable diluent in the presence of an acid acceptor, and the reaction mixture is stirred for several hours at the specifically required temperature. Working-up in process (c) is carried out in each case by customary methods.
To convert tlne compounds of the formula ( :I ) into salts, they are stirred with suitable salt formers, such as, for example, sodium hydroxide, sodium methylate, sodium ethylate, potassium hydroxide, potassium methylate or potassium ethylate, ammonia, isopropylamine, dibutylamine or triethylamine, using suitable diluents, such as, for example, water, methanol or ethanol. The salts can be isolated as crystalline products - then if appropriate after concentrating the mixture.
The active compounds can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense; there are to be understood all plants which grow in locations where they are undesired. Whether the substances act as total or selective herbicides depends essentially on the amount used.
The active compounds can be used, for example; in connection. with the following plants:
Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria,. Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Tpornoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus; Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, );mex, Datura, Viola, Galeopsis; Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.
Dicotyledon cultures of the genera~ Gossypium, Glycine, Heta, Daucus, Phaseolus, Pj.sum, Solanum, Linum, Ipoznaea, Vicia, Nicoti_aIla, Lyropersleon, Arachis, E3rassica, Lar_tuca, Cucumis and Cucurbita.
Monacotyledon weeds of the Genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Branchiaria, Lolium, Bramus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactylactenium, Agrastis, Alopecurus and Apera.
Monocot~edon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.
However,-the use of-the active compounds is in no way restricted to these genera, but also extends in the same manner to other plants.
The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks,~and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields,. in lawns, turf, meadows and pastures, and for the selective cornbating of weeds in annual cultures.
The compounds of the formula (I) are suitable for combating monocotyledon and dicotyledon weeds both 'in the pre-emergence and the post-emergence method. They are - markedly more effective than, for example, isocarbamide.
To a certain extent, the compounds also Shaw a fungicidal action, far example against powdery mildews and against apple scab, and also against Pyricularia oryzae on rice.
The active campounds ca.n be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.
These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-act ive agents, that is emulsifying agents and/or dispersing agents and/or forming agents.
In the case of the use of water. as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene, or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions; mineral and vegetable oils, alcohols, such as ~ CA 02420329 2003-03-13 butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dixnethyl sulphoxide, as well as water.
As solid carriers there ~:re suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers fox granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as Well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalir~s and lecithins, and synthetic phospholipids, can be used in the formulations.
Further additives can be mineral and vegetable oils.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs, and metal phthalocyanine dyestuffs, and trace nutrients such as salts of ion, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.
For combating weeds, the active compounds as such' or in-the form of their formulations, can also be used as mixtures with known herbicides, finished formulations or tank mixes being possible.
Suitable herbicides for the mixtures are known herbicides, such as, for example, 1-amino-6-ethylthio-3~(2,2-dimethylpropy'1)-1,3,5-triazine-2,4(1H,3H)-dione (AMETHYDIONE) or N-(2-benzothiazolyl)-N, N'-dimethylurea (METABENZTHIAZURONj for combating weeds in cereals 4-amino-3-methyl-6-phenyl-1,2,4-t_riazin-5(4H)-one (METAMITRON) for combating weeds in sugar beet and 4-amino=6-(l,1-dimethylethyl)-3-methylthio-1,2,4-triazin-5(4H)-one (METRIHUZIN) for combating weeds in soya beans= furthermore also mixtures with 2,4-dichlorophenoxyacetic acid (2,4-D);

It is known that certain substituted amino-carbonylimadazolinones, such as, for example, 1-isobutyl-aminocarbonyl-2-imidazolidinone (isocarbamide), have herbicidal properties (cf. R. Wegler, Chemie der Pflanzenschutz-and Schadlingsbekampfungsmittel [Chemistry of Plant Protection Agents and Pesticides], Vol. 5, p. 219, Springer-Verlag, Berlin-Heidelberg-New York, 1977).
However, the action of this compound is not satisfactory in all respects. The new sulphonylaminocarbonyl-triazolinones are a subgroup of the broad class of compounds of the a general formula (T) R SOZ NH CO N N --- R

The active compounds can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense; there are to be understood all plants which grow in locations where they are undesired. Whether the substances act as total or selective herbicides depends essentially on the amount used.
The active compounds can be used, for example; in connection. with the following plants:
Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria,. Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Tpornoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus; Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, );mex, Datura, Viola, Galeopsis; Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

However,-the use of-the active compounds is in no way restricted to these genera, but also extends in the same manner to other plants.
The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks,~and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields,. in lawns, turf, meadows and pastures, and for the selective cornbating of weeds in annual cultures.
The compounds of the formula (I) are suitable for combating monocotyledon and dicotyledon weeds both 'in the pre-emergence and the post-emergence method. They are - markedly more effective than, for example, isocarbamide.
To a certain extent, the compounds also Shaw a fungicidal action, far example against powdery mildews and against apple scab, and also against Pyricularia oryzae on rice.
The active campounds ca.n be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.
These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-act ive agents, that is emulsifying agents and/or dispersing agents and/or forming agents.
