The invention relates to novel heterocyclyltriazolinones of the general formula (I) ##STR1## in which R.sup.1 represents hydrogen or represents alkyl or cycloalkyl, each of which is optionally substituted, R.sup.2 represents hydrogen, hydroxyl, mercapto or halogen or represents alkyl, alkenyl, alkinyl, cycloalkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, arylalkyl, amino or heterocyclyl, each of which is optionally substituted, and Het represents an optionally substituted heterocycle of the formula ##STR2## in which X in each case represents oxygen, sulphur, an NH group or an N-alkyl group, a process for their preparation and their use as herbicides.
该发明涉及一种新型杂环基
三唑啉酮,其通式为(I) ##STR1## 其中R.sup.1代表氢或代表取代的烷基或环烷基,R.sup.2代表氢、羟基、巯基或卤素,或代表取代的烷基、烯基、炔基、环烷基、烷氧基、烷
硫基、烷基亚砜基、烷基磺酰基、芳基烷基、
氨基或杂环基,Het代表一个可选取代的杂环,其通式为 ##STR2## 其中X在每种情况下代表氧、
硫、NH基或N-烷基基团,一种制备它们的方法以及它们作为
除草剂的用途。
