Acylated aminophenylureas, preparation and use as herbicides and plant growth regulators The compounds of the formula I or their salts ##STR1## in which G is a radical G1, G2 or G3 ##STR2## R.sup.1 is H or alkyl, R.sup.2 is COOH, CSOH or a derivative of the carboxyl or thiocarboxyl group, of 1 to 20 carbon atoms, or acyl of the type CO-R.degree. of 1-12 carbon atoms, or an imino, hydrazone or oxime derivative of the group CO-R.degree., and R.degree. , R.sup.3a, R.sup.4a, R.sup.3b, R.sup.4b, W, X, Y and Z are as defined in claim 1, are suitable as selective herbicides and plant growth regulators in crops. The preparation is carried out in analogy to known processes (see claim 5) by way of intermediates, some of which are new, from the group consisting of benzene-sulfonamides (II), benzenesulfonyl isocyanates (IV) and benzesulfonyl chlorides (VI) and heterocyclically substituted carbamates (III), amines (V) and/or (thio)-isocyanates (XIX).
酰化的氨基苯脲,制备和用作除草剂和植物生长调节剂。公式I的化合物或其盐##STR1##其中G是G1,G2或G3基团##STR2##R.sup.1为H或烷基,R.sup.2为1到20个碳原子的羧酸或硫代羧酸衍生物,或1-12个碳原子的CO-R.degree.酰基,或羧酰基,硫代羧酰基,或CO-R.degree.基团的亚胺,腙或肟衍生物,而R.degree.,R.sup.3a,R.sup.4a,R.sup.3b,R.sup.4b,W,X,Y和Z如权利要求1所定义,适用于作为作物中的选择性除草剂和植物生长调节剂。制备类似于已知过程(见权利要求5)的方法,通过来自苯磺酰胺(II),苯磺酰基异氰酸酯(IV)和苯磺酰氯(VI)以及杂环取代的氨基甲酸酯(III),胺(V)和/或(硫)-异氰酸酯(XIX)的中间体进行。
