Abstract

Herbicidal N-aryl-substituted nitrogen-containing heterocycles of the formula ##STR1## in which Het represents a heterocycle of the formula ##STR2## R.sup.1 represents hydrogen or halogen and R.sup.2 represents halogen, hydroxyl or represents a radical --Z.sup.2 --R.sup.8, PA1 where PA1 X.sup.1 represents oxygen, represents a --CH.sub.2 -- group, represents a ##STR3## group or represents a ##STR4## group, X.sup.2 represents nitrogen or a CH group, PA1 Z.sup.1 represents oxygen or sulphur, PA1 Z.sup.2 represents oxygen or sulphur, PA1 R.sup.3 and R.sup.4 independently of one another in each case represent hydrogen or alkyl, PA1 R.sup.5 and R.sup.6 either independently of one another in each case represent hydrogen or alkyl or together represent a double-linked alkanediyl radical PA1 R.sup.7 represents hydrogen, alkyl or represents optionally substituted aryl and PA1 R.sup.8 represents in each case optionally substituted alkyl, alkenyl, alkinyl or cycloalkyl.
