Abstract:
A process for preparing substituted cyanophenyluracils of the formula (I) ##STR12## in which R.sup.1 represents optionally fluorine- and or chlorine-substituted alkyl having 1 to 4 carbon atoms, R.sup.2 represents hydrogen, fluorine, chlorine, bromine or alkyl having 1 to 4 carbon atoms, R.sup.3 represents hydrogen, fluorine, chlorine or bromine and R.sup.4 represents amino, fluorine, chlorine or the grouping --N(R.sup.5)SO.sub.2 R.sup.6 in which R.sub.5 represents hydrogen or represents respectively optionally fluorine- and/or chlorine-substituted alkyl, alkylcarbonyl or alkylsulphonyl having in each case 1 to 6 carbon atoms in the alkyl groups, represents respectively optionally fluorine- and/or chlorine-substituted cycloalkylcarbonyl or cycloalkylsulphonyl having in each case 3 to 6 carbon atoms in the cycloalkyl groups, or represents respectively optionally fluorine- and/or chlorine-substituted phenylcarbonyl or phenylsulphonyl, and R.sup.6 represents optionally fluorine- and/or chlorine-substituted alkyl having 1 to 6 carbon atoms, represents optionally fluorine- and/or chlorine-substituted cycloalkyl having 3 to 6 carbon atoms, or represents respectively optionally fluorine- and/or chlorine-substituted phenyl wherein compounds of formula (II) ##STR13## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each as defined above, are reacted with compounds of formula (III) Z.sup.1 --CO--Z.sup.2 (III), in which Z.sup.1 and Z.sup.2 are identical or different and each represents fluorine, chlorine, bromine C.sub.1 -C.sub.4 alkoxy, phenoxy, imidazolyl or triazolyl, optionally in the presence of a reaction auxiliary and optionally in the presence of a diluent at temperatures between -20.degree. C. and +150.degree. C.
