Abstract: By a novel process, trifluoroacetoacet-anilides of the formula ##STR1## in which R.sup.1 is as defined in the description, can be prepared by reacting trifluoroacetoacetyl chloride with anilines of the formula ##STR2## if appropriate in the presence of an acid binder and if appropriate in the presence of a diluent.The compounds of the formula (I) are suitable intermediates for preparing herbicidally active uracil derivatives.

Abstract: The application describes a process for preparing 4-hydroxyanilines by the reaction of phenols with diazonium salts and subsequent reduction.

Abstract: The invention relates to the use of the compound N-(4-fluoro-phenyl)-N-isopropyl-chloroacetamide of the formula (I) ##STR1## which is known, as active compound in selective herbicidal compositions, for example for combating weeds in maize cultures, and to a new process for the preparation of this active compound.The compound (I) is obtained in very high yields by reacting N-isopropyl-4-fluoro-aniline with approximately equimolar amounts of chloroacetyl chloride at temperatures between 20.degree. and 150.degree. C. in the presence of an inert diluent, such as, for example, toluene, without addition of an acid binder.
