Abstract

The present invention relates to compounds of the formula (I) or salts thereof ##STR1## where R.sup.1, R.sup.2 or H, are saturated or unsaturated (substituted) aliphatic radicals or (substituted) phenyl, or R.sup.1 and R.sup.2 together with the N atom by which they are linked are a heterocyclic ring of the formula ##STR2## a indices independently of one another being an integer from 1 to 3, R.sup.3 is H, a saturated or unsaturated (substituted) aliphatic radical or a (substituted) phenyl, benzyl or phenethyl radical, or R.sup.2 and R.sup.3 together are an alkylene chain, PA0 R.sup.4 is H, a saturated or unsaturated aliphatic radical or alkoxy, and PA0 R.sup.5 is a (substituted) pyrimidinyl, triazinyl, triazolyl or bicyclic, nitrogen-containing heterocyclic radical, which have valuable herbicidal or plant growth-regulating properties.
