FIELD: organic chemistry, herbicides. ^ SUBSTANCE: invention relates to novel arylsulfonylureas of the formula (I): wherein Q means oxygen atom (O); Y means -CH or nitrogen atom (N); Z means N; R means hydrogen atom (H), (C1-C12)-alkyl, (C2-C10)-alkenyl; R1 means H, (C1-C3)-alkyl; R2 means H, halogen atom, (C1-C3)-alkyl, (C1-C3)-alkoxy-group wherein both latter residues are unsubstituted or mono- or multiple-substituted with halogen atom or (C1-C3)-alkoxy-group; R3 means H, halogen atom, (C1-C3)-alkyl, (C1-C3)-alkoxy-, (C1-C3)-alkylthio-groups wherein indicated alkyl-containing groups are unsubstituted or mono- or multiple-substituted with halogen atom, or mono- or bisubstituted with (C1-C3)-alkoxy- or (C1-C3)-alkylthio-groups, or it means -NR5R6 wherein R5 and R6 mean independently H, (C1-C4)-alkyl. Compounds of the formula (I) elicit herbicide activity and therefore they can be used for the selective control for harmful plants. Also, invention describes intermediate compounds and methods for synthesis of compound of the formula (I). ^ EFFECT: improved method of synthesis, valuable properties of compounds. ^ 14 cl, 22 tbl, 13 ex |
