ABSTRACT OP THE DISCLOSURE Herbicidally active N-substituted .alpha.-halogenoacetanilides of the general formula (XI), Image in which R represents an optionally substituted N-containing heterocyclic radical bonded via a ring nitrogen atom or represents the grouping Image an optionally substituted furyl or thiophenyl radical, alkenyl, alkynyl, alkoxy, alkylcarbonyl or an optionally substituted phonyl, phenoxy or phonylcarbonyl radical, A represents oxygen, sulphur or the grouping >NR3, B reprensents hydrogen, alkyl, halogenoalkyl, alkenyl, alkynyl, cycloalkyl, halogen, an optionally substituted aryl or aralkyl radical or the grouping -OR4, -SR4 or -NR3R4, R1 and R2, independently of one another, each represent hydrogen, alkyl, cycloalkyl, halogenoalkyl, alkoxyalkyl, alkenyl, alkynyl or optionally substituted phenyl, R3 represents hydrogen, alkyl or optionally substituted aryl, R4 represents hydrogen, alkyl, halogenoalkyl, alkenyl, alkvnyl, cycloalkyl or optionally substituted aralkyl, X1, X2 and X3 independently of one another, each represent hydrogon or alkyl and Hal roprosonts halogen, are prepared by a process, in which a haloacetanilide of the general formula Image in which Hal, X1, X2 and X3 have the above-mentioned meanings, is reacted with a compound of the general formula Image (XIII), in which R, R1 and R2 have the above-mentioned meanings and Y represents halogen, alkylsulphonyl or optionally substituted phenyl- sulphonyl, in the presence of an acid-binding agent and optionally in the presence of an organic solvent, it being possible optionally to react the compound of the formula (XIII) in the form of an acid addition salt.
