Substituted sulfonyldiamides, processes for their preparation, and their use as herbicides and plant growth regulators

摘要

The present invention relates to compounds of the formula (I) or salts thereof <IMAGE> (I) where R1, R2 or H, are saturated or unsaturated (substituted) aliphatic radicals or (substituted) phenyl, or R1 and R2 together with the N atom by which they are linked are a heterocyclic ring of the formula <IMAGE> a indices independently of one another being an integer from 1 to 3, R3 is H, a saturated or unsaturated (substituted) aliphatic radical or a (substituted) phenyl, benzyl or phenethyl radical, or R2 and R3 together are an alkylene chain, R4 is H, a saturated or unsaturated aliphatic radical or alkoxy, and R5 is a (substituted) pyrimidinyl, triazinyl, triazolyl or bicyclic, nitrogen-containing heterocyclic radical, which have valuable herbicidal or plant growth-regulating properties.
