Sulfonylurea derivatives of the formula
wherein Ar is an optionally substituted bicyclic moiety;
R, is a substituted mono- or bicyclic heterocyclic moiety; and
R10 is H or CH3;
and their agriculturally suitable salts exhibit general and selective herbicidal activity. They may be formulated for use in conventional manner.
The novel compounds may be made e.g. by reacting an appropriate sulfonyl isocyanate of formula ArSO2NCO with a corresponding heterocyclic amine of formula HNR10R1.
式中 Ar 为任选取代的双环分子;R 为取代的单环或双环杂环分子;R10 为 H 或 CH3 的磺酰脲衍生物及其农业上适用的盐类具有一般的和选择性的除草活性。 它们可按常规方法配制使用。 新型化合物可通过将式 ArSO2NCO 的适当磺酰基异氰酸酯与相应的式 HNR10R1 的杂环胺反应制成。

N-[Heterocyclicaminocarbonyl]-1H-indene and tetrahydronaphthalene sulfonamides, such as 2,3-dihydro-N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-1H-indene-4-sul fonamide, are useful for the regulation of plant growth and as preemergent and postemergent herbicides.
