Herbicidal 5-halo-1-halophenyl-1H-pyrazole-4-carbonitriles

The present invention is directed to herbicidal compounds of the formula STR1 wherein each R1 independently is halogen; R2 is halo or trifluoromethyl; and n is 1-5; with the provisos that when n is 1, R1 is other than fluorine, and when n is 2 and each R1 is chlorine, at least one R1 is located at a para or ortho position on the phenyl ring.

N-Phenylpyrazole derivatives

N-Phenylpyrazole derivatives of the formula: STR1 (wherein each of R5 and R6 represents a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical, or a fluorine, chlorine or bromine atom, each of R7, R8 and R9 represents a hydrogen atom, a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical or a fluorine, chlorine or bromine atom, or R5, R7, R8 and R9 each represents a hydrogen atom and R6 represents a trifluoromethoxy or trifluoromethyl radical, and R10 represents a cyano radical or substituted carbamoyl radical --CONHR11, wherein R11 represents a methyl or ethyl radical) have been found to possess useful herbicidal properties. All such N-phenylpyrazole derivatives with the exception of 5-amino-4-cyano-1-(2,4-dichlorophenyl)pyrazole and 5-amino-4-cyano-1-(4-chloro-2-methylphenyl)pyrazole are new compounds. Herbicidal compositions containing such N-phenylpyrazole derivatives are described and also processes for the preparation of the new compounds.

5-Acylamino-4-cyano-1-phenylpyrazole derivatives and use as herbicides

New acylamino-N-phenylpyrazole derivatives of the formula: STR1 [wherein R1 represents R8 C(=O)--(wherein R8 represents H, C1-7 alkyl or C1-4 alkoxy optionally substituted by C1-4 alkoxy, C2-5 alkoxycarbonyl or halogen, C3-4 alkenyloxy, C3-6 cycloalkyl optionally substituted by CH3 or C2 H5, or phenoxy, R2 represents H or R8 C(=O)--, or R1 and R2 together represent --CO--(CRa Rb)m --CO--, R3 represents F, Cl, Br, C1-4 alkyl optionally substituted by halogen, or C2-4 alkenyl, R4 represents F, Cl, Br, NO2, CH3 or C2 H5 and R5, R6 and R7 represent H, F, Cl, Br, NO2, CH3 or C2 H5, or R4 and R5 each represent Cl and R3, R6 and R7 each represent H, Ra and Rb represent H or C1-4 alkyl, and m is 2 or 3] possess useful herbicidal properties.
