The invention relates to novel substituted phenyl uracils of general formula(I), wherein n represents the numbers 0, 1, 2 or 3, Q represents O, S, SO, SO2, NH or N (alkyl), R1 represents hydrogen, amino or optionally substituted alkyl, R2 represents carboxy, cyano, carbamoyl, thiocarbamoyl or optionally substituted alkyl or alkoxycarbonyl, R3 represents hydrogen, halogen or optionally substituted alkyl, R4 represents nitro, amino or one of the following groupings - NH-CO-R7 or -N(CO-R7)2, R5 represents nitro, amino, hydroxy, mercapto, carboxy, cyano, carbamoyl, thiocarbamoyl, sulfo, chlorosulfonyl, aminosulfonyl, halogen or optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl, alkylcarbonylamino, alkoxycarbonylamino, alkylsulfonylamino or bis-alkylsulfonyl-amino, R6 represents optionally substituted aryl or optionally substituted heterocyclyl from the series of furyl, tetrahydrofuryl, benzofuryl, dihydrobenzofuryl, dioxolanyl, dioxanyl, benzodioxanyl, pyrrolyl, imidazolyl, benzimidazolyl, triazolyl, oxazolyl, isoxazolyl, benzoxazolyl, thiazolyl, isothiazolyl, benzothiazolylpyridinyl, quinolinyl, isochinolinyl, pyrimidinyl, pyrazolyl, pyrazinyl, pyridazinyl, quinazolinyl, quinoxalinyl and R7 represents hydrogen or optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heteroxycyclylalkyl. The invention also relates to the use of the inventive phenyl uracils as herbicides, to a method for producing them, and to substituted phenyl urethanes (phenyl carbamates) of general formula (III), wherein A2 represents alkyl, aryl or arylalkyl as intermediate products.
