FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to novel N-(5-iodo-2-methoxycarbonylphenyl)sulfonylures of the formula (I): wherein R means unsubstituted (C1-C12)-alkyl or substituted with one or more residues from group comprising halogen atom, (C1-C6)-alkoxy-group, (C1-C6)-alkylthio-group, (C1-C6)-halogenalkoxy-group and unsubstituted phenyl or substituted up to three-fold with similar or different residues chosen from group comprising (C1-C4)-alkyl, (C1-C4)-alkoxy-group, (C1-C4)-halogenalkyl, (C1-C4)-halogenalkoxy-group, -CN and nitro-group; or unsubstituted (C3-C12)-cycloalkyl or substituted with one or more residues from group comprising halogen atom, (C1-C4)-alkyl, (C1-C4)-halogenalkyl, (C1-C4)-alkoxy-group, (C1-C4)-halogenalkoxy-group and (C1-C6)-alkylthio-group. Compounds of the formula (I) are intermediate substances used in synthesis of herbicide sulfonylureas that, in turn, show high exploitation indices.
EFFECT: improved method of synthesis, valuable properties of compounds.
