ABSTRACT:
1-alkyl-3-arylimidazolidine-2,4-diones are prepared by reacting the herbicidally active intermediate N-phenyl-2-substituted-2-alkylamino acetamides with 1,1'-carbonyldiimidazole in a suitable solvent. These herbicidally active intermediates are prepared by reacting alpha-haloacetanilides with the primary amine of choice in an alcohol solvent, in the presence or absence of water, at ambient temperature.
