Substituted aminomethylenemalonate, the retrieval method, herbicide tool based on them, the way of weed control and intermediate compounds
The invention relates to new substituted aminomethanesulfonic General formula (I) possessing a highly effective herbicide action, as well as the way they are received, herbicide tool based on these intermediate compounds of General formula (II). In the compounds of General formula (I) Z means Metin or nitrogen, R1group NR6R7in which R6is alkyl with 1-4 carbon atoms, and R7is hydrogen or alkyl with 1-4 carbon atoms; alkyl with 1-4 carbon atoms; n = 0, 1 or 2 except for the values 0 or 1 when R1means a group NR6R7; R2and R3independently from each other hydrogen or alkyl with 1-4 carbon atoms; R4is hydrogen or alkyl with 1-4 carbon atoms, R5- formyl, alkylsulphonyl with 1-4 carbon atoms in the alkyl group which may be substituted by one or more Halogens; alkenylboronic with 2-4 carbon atoms in alkenylphenol part, alkenylboronic with 2-4 carbon atoms in alkenylphenol part, alkylsulfonyl with 1 to 4 carbon atoms in which alkyl group may be substituted by one or more Halogens; cycloalkylcarbonyl with 3-6 carbon atoms in cycloalkyl part, alkoxycarbonyl with 1-4 carbon atoms in alkoxyimino parts and other values specified in the claims. The method of obtaining compounds of General formula (I) or their salts is that sulfonylation General formula (II) is subjected to interaction with aminoheterocycles General formula (III) and the target product is isolated in free form or in salt form. Herbicide tool contains a compound of the formula (I) or its salt and normal in plant protection auxiliary means for receiving preparative forms. Method of weed control is applied to plants, plant seeds or planting area an effective amount of the compounds of formula (I) or its salt. 5 S. and 2 C. p. F.-ly, 2 PL.
