Abstract

New and valuable substituted O-[aminosulfonyl]-glycolic anilides and a process for controlling the growth of unwanted plants with these compounds.

Description

The present invention relates to new and valuable substituted O-[aminosulfonyl]-glycolic anilides, their preparation and use as herbicides.

It is known to use chloroacetic acid-N-isopropylanilide as a herbicide. However, its biological action is only moderate.

We have now found that substituted O-[aminosulfonyl]-glycolic anilides of the formula ##EQU1## where R.sup.1 denotes hydrogen, alkyl, haloalkyl or cycloalkyl, R.sup.2 denotes phenyl and R.sup.3 denotes alkyl, alkenyl, alkynyl, cycloalkyl or benzyl, have a good herbicidal action.

R.sup.1 may be, inter alia, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, pentyl, cyclopentyl, hexyl, cyclohexyl 2-chloroethyl.

R.sup.3 may be, inter alia, methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl, cyclopentyl, hexyl, cyclohexyl, allyl, butenyl, pentenyl, hexenyl, propargyl, butynyl, pentynyl, hexynyl, benzyl.

The herbicidal action of the new compounds is particularly in evidence on the following weeds:

Alopecurus myosuroides slender foxtailAmaranthus spp. amaranth speciesAvena fatua wild oatBromus spp. brome speciesChenopodium spp. goosefoot speciesDactylis glomerata orchardgrassDigitaria sanguinalis large crabgrassEchinochloa crus-galli barnyardgrassEleusine indica goosegrassGalium aparine catchweed bedstrawLamium spp. deadnettle speciesLolium spp. ryegrass speciesMatricaria chamomilla chamomilePanicium spp. panicum spp.Poa spp. bluegrass speciesSetaria spp. foxtail speciesSinapis arvensis wild mustardwithout causing damage to the crop plants:Allium cepa onionsBeta vulgaris beetBrassica spp. cabbage speciesCucumis sativus cucumbersDaucus carota carrotsGossypium hirsutum cottonHelianthus annuus sunflowerHordeum vulgare barleyLactuca spp. lettuce speciesLinum usitatissimum flaxMedicago sativa alfalfaOryza sativa ricePetroselinum sativum parsleyPisum sativum peasPhaseolus spp. beansSecale cereale ryeSoja hispida (Glycine max.) soybeansSolanum tuberosum potatoesSpinacia oleracea spinachSorghum bicolor sorghumTriticum aestivum wheatTrifolium spp. cloverZea mays Indian corn

Application rates are from 0.2 to 5 kg of active ingredient per hectare; the compounds may be applied before sowing, or before or after emergence of the plants.

The compounds of the invention may be prepared by reacting a substituted glycolic anilide with a substituted aminolsulfonyl chloride in the presence of an acid acceptor, e.g., triethylamine and pyridine.

EXAMPLE 1

O-[isopropylaminosulfonyl]-glycolic acid-N-butyn-1-yl-3-anilide

At 0.degree. to 5.degree.C and while stirring, a solution of 333 parts by weight of isopropylaminosulfonyl chloride in 80 parts by weight of dichloromethane was added to a solution of 35.5 parts by weight of glycolic acid-N-butyn-1-yl-3-anilide and 21.4 parts by weight of triethylamine in 600 parts by weight of dichloromethane. After 2 hours the reaction mixture was successively washed with dilute hydrochloric acid, water, sodium bicarbonate solution, and again with water, and then dried with magnesium sulfate. The crude product, melting at 99.degree. to 105.degree.C, was obtained from the organic phase upon concentration in vacuo. The pure compound melting at 108.degree. to 110.degree.C may be obtained by recrystallization from benzene.

Glycolic acid-N-butyn-1-yl-3-anilide

264 Parts by weight of chloroacetic acid-N-butyn-1yl-3-anilide (obtained from chloroacetyl chloride and N-butyn-1-yl-3-aniline) and 660 parts by weight of potassium acetate were boiled under reflux for 20 hours in 2,400 parts by weight of 1.5 molar acetic acid. After cooling, the O-acetylglycolic acid-N-butyn-1-yl-3-anilide which had formed was suction filtered and reacted as a crude product (m.p. 83.degree. to 87.degree.C). The pure compound (m.p. 95.degree. to 96.degree.C) is obtained by recrystallization from cyclohexane.

77 Parts by weight of crude O-acetylglycolic acid-N-butyn-1-yl-3-anilide was dissolved in a solution of 31 parts by weight of potassium hydroxide in 890 parts by weight of methanol and left to stand at room temperature for 16 hours. The reaction solution was then concentrated to roughly 150 ccm. Upon neutralization of the residue with dilute hydrochloric acid crystals of crude glycolic acid-N-butyn-1-yl-3-anilide separated out; m.p.: 65.degree. to 67.degree.C.

This crude product was purified by recrystallization from benzene/ligroin; m.p. 74.degree. to 76.degree.C.

The following compounds were obtained analogously: glycolic acid-N-isopropylanilide, m.p. 59.degree. to 60.degree.C glycolic acid-N-isobutylanilide, m.p. 53.degree. to 54.degree.C glyolic acid-N-tert-butylanilide, m.p. 55.degree. to 56.degree.C.

Glycolic anilides are obtained in the same manner by reacting, in accordance with the scheme shown below, N-alkylanilines with 1,3-dioxolane-2,4-dione (J. Chem. Soc., 1357, 1951). R.sup.2 and R.sup.3 have the meanings given above. ##EQU4##

The reaction mixture was then stirred at room temperature until no more carbon dioxide evolved, and subsequently concentrated to dryness in vacuo. The crude product obtained melts at 48.degree. to 50.degree.C; the analytically pure compound is obtained by recrystallization from ether; m.p.: 50.degree. to 52.degree.C.

The following compounds were obtained analogously:

The agents according to the invention may be used as solutions, emulsions, suspensions or dusts. The form of application depends entirely on the purpose for which the agents are being used; in any case it should ensure a fine distribution of the active ingredient.

For the preparation of solutions to be sprayed direct, hydrocarbons having boiling points higher than 150.degree.C, e.g. tetrahydronaphthalene or alkylated naphthalenes, or organic liquids having boiling points higher than 150.degree.C and having one or more than one functional group, e.g. the keto group, the ether group, the ester group or the amide group, this group or these groups being attached as substituent(s) to a hydrocarbon chain or being a component of a heterocyclic ring, may be used as spray liquids.

Aqueous formulations may be prepared from emulsion concentrates, pastes or wettable powders by adding water. To prepare emulsions the ingredients as such or dissolved in a solvent may be homogenized in water or organic solvents by means of wetting or dispersing agents, e.g., polyethylene oxide adducts. Concentrates which are suitable for dilution with water may be prepared from active ingredient, emulsifying or dispersing agent and possibly solvent.

Dusts may be prepared by mixing or grinding the active ingredients with a solid carrier, e.g., kieselguhr, talc, clay or fertilizers.

Granules may be prepared by applying the active ingredients to solid carriers of various particle sizes.

Adherents, oils and other herbicidal active ingredients may also be added.
