FIELD: organic chemistry, chemical technology, herbicides, agriculture.
SUBSTANCE: invention relates to new sulfonamides of the formula (I):
and their salt wherein A represents substituted or unsubstituted benzene ring or 5-membered, or 6-membered substituted or unsubstituted heteroaromatic ring taken among the group comprising thienyl, pyrazolyl, imidazolyl, pyridyl wherein optional substitutes are taken among the group consisting of halogen atom, substituted or unsubstituted (C1-C4)-alkyl, unsubstituted or substituted (C1-C4)-alkoxy-group, nitro-group, phenyl, phenoxy-group, benzoyl and (C1-C4)-alkylcarboxylate when any alkyl fragment in the latter indicated substituted is substituted with one or some halogen atoms, (C1-C4)-alkoxy-groups, cyano-group and phenyl; Q represents -O-, -S- or group of the formula: -CXX' wherein X and X' can be similar or different and each represents hydrogen atom, halogen atom, cyano-group, alkyl comprising 1-8 carbon atoms, or the group -ORa, -SRa; or one of X and X' represents hydroxy-group and another has values determine above; Ra means (C1-C8)-alkyl, phenyl; Rb means (C1-C8)-alkyl, phenyl; Y means nitrogen atom or the group CR9; R1 means unsubstituted (C1-C8)-alkyl or that substituted with halogen atom, cyano-group, phenyl or (C1-C4)-alkoxycarbonylamino-group, or it represents phenyl; R2 means hydrogen atom (H), (C1-C4)-alkyl; R3 and R4 can be similar or different and each represents (C1-C4)-alkyl, (C1-C4)-alkoxy-group, halogen atom; R9 means hydrogen atom (H) under condition that when Q represents oxygen atom (O) or -S- then ring A represents 5-membered substituted or unsubstituted heteroaromatic ring and determined above. Compounds of the formula (I) possess the herbicide activity that allows their using for eradication of weeds. Also, invention describes a method for preparing compounds of the formula (I).
EFFECT: improved preparing method, valuable properties of compounds.
