  • hydrogen atoms e.g. allyl butene (1) yl (3)
  • alkynyl with 3 to carbon atoms e.g.
  • cycloalkyl with 5 to 8 carbon atoms optionally substituted by alkyl with 1 to 4 carbon atoms e.g. cyclopentyl, cyclohexyl, 3-methylcyclohexyl, 2,6-dimethylcyclohexyl, cycloheptyl, 4-tert-butylcyclohexyl, 3,5-dimethylcyclohexyl

  • n 1 to 4 and A, B, D, E each independently represent oxygen or sulfur, where not all radicals A, B, D, E simultaneously represent oxygen and where at least one of these radicals always means sulfur, a good herbicidal action against numerous important unwanted plants (e.g. Euphorbia and Chenopodium) and at the same time have a good tolerance for many crops (e.g. cotton and corn). These effects are better than those of the known active ingredients.
  • the new connections can be made, for example, using the following methods, where the radicals A, B, D, E, R, R 1 , R 2 , R 3 , R 4 , X and n have the meaning given above.

  • meta-nitrophenyliso (thio) cyanates B
  • B meta-nitrophenyliso (thio) cyanates
  • the aminourethanes F can also be obtained by reacting meta-phenylenediamines (D) with chloroformic acid esters.
  • Another synthesis possibility is the reaction of aryl-1,3-diiso (thio) cyanates (E) with only one mole of component R 3 -BH, which leads to the iso (thio) cyanatourethanes (G) (JA Parker, JJ Thomas and CL Zeise, J. org. Chem. 22, 594 to 596 (1957)), which can also be obtained by (thio) phosgenation of the aminourethanes (F) (DT-OS 19 14 270, page 5, example 8). Subsequent reaction with component R 4 DH leads to the desired end products. Basically, it should be noted that the order of the -CABR 3 or -EDR 4 groupings is arbitrary.
  • connection has the following structural formula:
  • connection has the following structural formula:
  • connection has the following structural formula:
  • aminourethanes (F) can be prepared by appropriate processes:
  • connection has the following structural formula:
  • a mixture of 20 parts by weight of N- (3-isothiocyanatophenyl) -O-methylcarbamate (obtainable from N- (3-aminophenyl) -0-methylcarbamate and thiophosgene, mp. 99-100 ° C., 20 parts by weight of methanol, 3 parts by weight of triethylamine and 150 parts by weight of toluene are boiled for 6 hours, after which the mixture is recrystallized from toluene: mp 147-149 ° C. (No. 2).
  • connection has the following structural formula:
  • connection has the following structural formula:
  • 3-methoxycarbonylaminophenyl-N- (3'-methyl-phenyl) -carbamate and 3-ethylcarbonylaminophenyl-N-phenylcarbamate are characterized by their, albeit different, activity against broad-leaved unwanted plants with a considerable degree of tolerance for Sugar beet.
  • 3-methoxycarbonylaminophenyl-N- (3'-methylphenyl) carbamate has an even more favorable selectivity in this culture than the second compound of this type mentioned above.
  • 3-Isopropyl-2,1,3-benzothiadiazinon (4) -2,2-dioxide has a completely different field of application. This compound is used to control various broad-leaved weeds in soybeans, peanuts, cereals, corn and some types of vegetables. However, there are still gaps in effectiveness here.
  • 3-methoxycarbonylaminophenyl-N- (3'methyl-phenyl) carbamate hardly shows at for its class good herbicidally active crop selectivity, which is why the connection example for soybeans was recommended only for sub-leaf spraying (post- di re cted) (Arndt, F and G Boroschewsky; New Selective Herbicides - VIII International Plant Protection Congress, Reports and Information, Section 111 Chemical Control, Part I, Moskow 1975, pp. 42-4.9).
  • the young shoots and leaves of the crop plants should not be hit by the spray mixture, but undesirable plants that are located underneath them.
  • Plastic flower pots with a content of 300 cm 3 were filled with loamy sand and equipped with the test plants according to species. This mainly involves sowing seeds or transplanting vegetatively propagated species.
  • the active ingredients were suspended or emulsified in water as a distribution medium and sprayed onto the leaves of the test plants and the still exposed soil surface using fine-spreading nozzles in post-emergence application.
  • the plants were first grown to a height of 3 to 10 cm in the test vessels, depending on the growth habit, and then treated.
  • the temperature requirements of the test plants were met by placing them in cooler or warmer sections of the greenhouse systems.
  • the trial period lasted 2 to 4 weeks. During this time, the plants were cared for and their reaction to the individual treatments evaluated.

  • the application forms depend on the purposes; in any case, they should ensure the finest possible distribution of the active compounds according to the invention.
  • Mineral oil fractions of medium to high boiling point such as kerosene or diesel oil, also coal tar oils, and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, for example benzene, toluene, xylene, are used to produce directly sprayable solutions, emulsions, pastes and oil dispersions.

  • Powders, materials for broadcasting and dusts can be prepared by mixing or grinding the active substances together with a solid carrier.
