ABSTRACT:
The invention relates to novel substituted phenyluracils and novel intermediates for their preparation and to their use as herbicides.
Certain substituted aryluracils are already known from the (patent) literature (cf. EP-A-255047, EP-A-260621, EP-A-408382, EP-A-438209, EP-A-473551, EP-A-517181, EP-A-563384, WO-A-91/00278, WO-A-91/07393, WO-A-93/14073, WO-A-98/41093, U.S. Pat. No. 4,979,982, U.S. Pat. No. 5,084,084, U.S. Pat. No. 5,127,935, U.S. Pat. No. 5,154,755, U.S. Pat. No. 5,169,430, U.S. Pat. No. 5,486,610, U.S. Pat. No. 5,356,863). However, these compounds have hitherto not attained any particular importance.
This invention, accordingly, provides novel substituted phenyluracils of the general formula (I)
in which
n represents the numbers 0, 1 or 2,
R
1
represents hydrogen, amino or optionally substituted alkyl,
R
2
represents carboxyl, cyano, carbamoyl, thiocarbamoyl or in each case optionally substituted alkyl or alkoxycarbonyl,
X represents hydroxyl, mercapto, amino, nitro, cyano, carboxyl, carbamoyl, thiocarbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylcarbonyloxy, alkoxycarbonyloxy, alkylaminocarbonyloxy, dialkylaminocarbonyloxy, phenylcarbonyloxy, alkylcarbonylamino, alkoxycarbonylamino, alkylsulphonylamino, alkenyl, alkenyloxy, alkenyloxycarbonyl, alkinyl, alkinyloxy or alkinyloxycarbonyl—where in the case that n is greater than 1, X in the individual possible compounds may also have meanings other than those given.
In the definitions, the hydrocarbon chains, such as alkyl, are in each case straight-chain or branched—including in combination with heteroatoms, such as in alkoxy.
If the compounds of the general formula (I) according to the invention contain substituents with asymmetric carbon atoms, the invention relates in each case to the R enantiomers and the S enantiomers, and to any mixtures of these enantiomers, in particular the racemates.
n preferably represents the numbers 1 or 2.
