Patent number: 6245714
Abstract: New substituted phenyl uracils are described which have general formula (I),
in which R1 is halogen, or optionally substituted alkyl, R2 is optionally substituted alkyl, R3 is an amino group or optionally substituted alkyl, alkenyl or alkynyl, R4 is a cyano group or halogen, R5 is a cyano group or thiocarbamoyl, R6 group (2) or group (3)
in which Q1 and Q2 are oxygen or sulphur, R7 is hydrogen or optionally substituted alkyl, R8 is hydrogen or optionally substituted alkyl, alkoxy, alkylamino, dialkylamino, alkylcarbonylamino, alkylsulfonylamino, alkenyl, alkenyloxy, alkynyl, cycloalkyl, cycloalkyloxy, cycloalkylamino, cycloalkylcarbonylamino, cycloalkylsulfonylamino, aryl, aryloxy, arylamino, arylcarbonylamino, arylsulfonylamino, arylalkyl, arylalkoxy or arylalkylamino group, R9 and R10 are alkyl. A method for production of said compounds and their use as herbicides are described.

Patent number: 6172225
Abstract: The invention relates to a novel process for producing thereof hydroxyarenes of the general formula (I)
in which
n represents the numbers 1, 2, 3 or 4,
R represents cyano, carboxyl, formyl, nitro, halogen or represents alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylcarbonyl or alkoxycarbonyl, each of which is optionally substituted, and
Z represents hydrogen, cyano, nitro, halogen, alkyl, halogenoalkyl, or represents monocyclic or bicyclic, saturated or unsaturated heterocyclyl, heterocyclylamino or heterocyclylimino, each of which is optionally substituted,
characterized in that halogenoarenes of the general formula (II)
in which
n, R and Z are each as defined above and
X represents halogen
are reacted with 3-hydroxy-propionitrile of the formula (III),
HO—CH2CH2—CN (III),
if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, at temperatures between 0° C. and 100° C.

Patent number: 6077812
Abstract: Novel herbicidal compounds, compositions containing them, and methods for their use in controlling weeds are disclosed. The novel herbicidal compounds are represented by formula I: ##STR1## where J is a 1-substituted-6-trifluoromethyl-2,4-pyrimidinedione-3-yl, a 1-substituted-6-trifluoromethyl-1,3,5-triazine-2,4-dion-1-yl, a 3,4,5,6-tetrahydrophthalimid-1-yl, a 4-difluoromethyl-4,5-dihydro-3-methyl-1,2,4-triazol-5(1H)-on-1-yl, a 5,6,7,8-tetrahydro-1H,3H-[1,3,4]thiadiazolo[3,5-a]pyridazineimin-1-yl, or a 1,6,8-triazabicyclo[4.3.0]-nonane-7,9-dion-8-yl ring attached at the 7 position of a benzofuran, benzoxazole, indole, 2,3-dihydrobenzimidazole or benzimidazole, and X is selected from hydrogen, halogen, cyano, nitro, and amino. Preferred R groups are optionally substituted alkyl groups.
