Abstract

NES MATERIAL:3-Chloro-4-fluorophenyl urea of formula VI (R, R' are H, alkyl, lower alkoxy, benzly, carboxymethyl). EXAMPLE:N'-(3-chloro-4-fluorophenyl)-N-methyl-N-methoxyurea USE:Herbicide having excellent selectivity, high safety, and strong herbicidal activity, and applicable to any growth stage of weeds. PROCESS:The compound VI is prepared either by reacting 3-chloro-4-fluorophenyl isocyanate I with an amine II in a solvent, or by reacting 3-chloro-4-phenylaniline III with carbamoyl halogenide IV in a solvent in the presence of a base.
