Novel N-[pyrimidin-2-yl]- and [triazin-2-yl]aminocarbonyl-1,3-benzodioxolesulfonamides and 1,4-benzodioxansulfonamides are useful as plant growth regulants and in particular as herbicides.
N-[Heterocyclicaminocarbonyl]-8-quinolinesulfonamides such as N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-8-quinolinesulfonamide or N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-8-quinolinesulfonamide are useful for plant growth retardation, brush control and weed control in crops.

Compounds of formula (I), where R.sup.1, R.sup.2, n, W, R.sup.3 and A are as defined in claim 1, are suitable for use as herbicides and plant growth regulators. They can be produced by a process similar to known processes. To produce them, new compounds of formula (II) are reacted with a carbamate of formula R*--O--CO--NR.sup.3 A, where R.sup.3 stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.
公式(I)的化合物,其中R.sup.1,R.sup.2,n,W,R.sup.3和A的定义如权利要求1所述,适用于用作除草剂和植物生长调节剂。它们可以通过类似于已知过程的过程生产。为了生产它们,公式(II)的新化合物与公式R * - O - CO - NR.sup.3 A的氨基甲酸酯反应,其中R.sup.3代表苯基或烷基。公式(II)的化合物可以从相应的磺酰氯化物中获得。
