Date Mar. 27, 1997A composition comprising at least one sulfonylurea of the formula I wherein R1 is substituted alkyl; halogen; a group ER6 (E=O, S or NR7); COOR8; NO2; S(O)oR9; SO2NR10R11; or CONR10R11; R2 is hydrogen, alkyl, alkenyl, alkynyl, halogen, alkoxy, haloalkoxy, haloalkyl, alkylsulfonyl, nitro, cyano or alkylthio; R3 is F, CF3, CF2Cl, CF2H, OCF3, OCF2Cl, or, if R1 is CO2CH3 and R2 is simultaneously fluorine, R3 is Cl, or, if R1 is CH2CF3 or CF2CF3, R3 is methyl, or, if R4 is OCF3 or OCF2Cl, R3 is OCF2H or OCF2Br; R4 is alkoxy, alkyl, alkylthio, alkylamino, dialkylamino, halogen, haloalkyl or haloalkoxy; and R5 is hydrogen, alkoxy or alkyl; or an enviromentally compatible salt of I, and an aryloxyalkanoic acid selected from the group consisting of 2,4-D, 2,4-DB, clomeprop, dichlorprop, dichlorprop-P, dichlorprop-P (2,4-DP-P), fenoprop (2,4,5-TP), fluoroxypyr, MCPA, MCPB, mecoprop, mecoprop-P, napropamide, napropanilide, triclopyr, and an enviromentally compatible salt thereof exhibits a synergistic herbicidal effect.
Preparation of 5-(2-halo-4-trifluoromethylphenoxy)-2-nitrobenzoic acid and salts and esters and amides
-
, (2008/06/13)
A process for preparing a substantially pure, isomer free 5-(2-halo-4-trifluoromethylphenoxy)-2-nitrobenzoic acid or its esters, salts and amides by the basic condensation of a 4-trifluoromethylphenol and a 1-chloro-3-substituted-4-nitrobenzene followed by halogenation. All known previous routes afforded, in addition to the desired product, a number of inactive isomers.

, (2008/06/13)
Compounds of the formula STR1 wherein X is a cyano group, Y is a hydrogen atom, a halogen atom, or a trihalomethyl group, and Z is a substituted alkoxy group, and compositions containing these compounds exhibit herbicidal activity.
Preparation of trifluoromethylphenyl nitrophenylethers
-
, (2008/06/13)
A process for preparing trifluoromethylphenyl nitro phenylethers which comprises treating a trifluoromethylhalobenzene with a base in a cosolvent system to afford a trifluoromethyl phenolate which may be isolated as its free phenol or reacted with an appropriately substituted halobenzene to afford a diphenylether herbicide or a precursor thereto.
