ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to novel 1-arylpyrazolecarboxaldehyde oximes, compositions, and derivatives thereof. It relates to their unexpected and useful systemic insecticidal activity. The invention particularly pertains to compositions of said compounds and methods, using said compounds, for the control of arthropod. nematode, helminth or protozoan pests. In particular to the application of said compounds or compositions in agricultural methods of use, particularly as pesticides, for controlling arthropods, especially insects by systemic action. The invention also relates to 1-arylpyrazole hydrazones.
2. Description of the Related Art
The control of insects, nematodes or helminths by means of active material having a 1-arylpyrazole group therein has been described by many patents or patent application such as International Patent Publication No. WO 93/06089 (and the equivalent U.S. Pat. No. 5,451,598), WO 94/21606 and WO 87/03781 as well as in European Patent Publication Numbers 0295117, 659745, 679650, 201852 and 412849, German Patent No. DE19511269 and U.S. Pat. No. 5,232,940.
Other compounds are disclosed in WO 92/13451, Aug. 20, 1992, to Schering Agrochemicals Ltd., which describes 5-chloro-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4,5-dicyano-1H-imadazol-2-yl)-3-hydroxyiminomethyl-1H-pyrazole as an intermediate, also with activity against a single species

, sleep blow fly.
This Schering reference appears to be the only reference describing 1-arylpyrazole-oxime compounds as insecticides.
It is an object of the present invention to provide new pesticidal compounds of the 1-arylpyrazole family together with processes for their preparation.
A second object of the present invention is to provide pesticidal compositions and pesticidal methods of use of the pesticidal pyrazole compounds against arthropods, especially insects, plant nematodes, or helminth or protozoan pests, particularly in agricultural or horticultural crops, forestry, veterinary medicine or livestock husbandry, or in public health.
A third object of the present invention is to provide very active compounds, with broad spectrum pesticidal activity, as well as compounds with selective special activity, e.g., aphicidal, miticidal, foliar insecticidal, soil insecticidal and nematicidal, systemic, antifeeding or pesticidal activity via seed treatment.
A fourth object of the present invention is to provide compounds with substantially enhanced and more rapid activity, especially against insects and more particularly insects in their larval stages.
A fifth object of the present invention is to provide compounds with greatly improved (greater and faster) penetration into pest species when topically applied and thus provide enhanced movement of the compounds to the pesticidal site(s) of action within the pest.
Another object of the present invention is to provide compounds with high activity and improved safety to the user and the environment.
These and other objects of the invention shall become readily apparent from the detailed description of the present invention. These objects are met in whole or in part by the instant invention.

By the term “pesticidally acceptable salts” is meant salts the anions and cations of which are known and accepted in the art for the formation of pesticidally acceptable salts. Preferably such salts are water soluble. Suitable acid addition salts formed from compounds of formula (I) containing an amine group, include salts with inorganic acids for example hydrochlorides, phosphates, sulfates and nitrates, and salts with organic acids for example acetates. Suitable base addition salts formed from compounds of formula (I) containing a carboxylic acid group, include alkali metal (for example sodium or potassium) salts, ammonium salts and organic amine (for example diethanolamine or morpholine) salts.
Compounds of formula (I) wherein R
1
represents —NR

in which R

Such tautomerism is well known as is described in S.Patai (The Chemistry of Functional Groups: Amidines and Imidates, Vol 2, 1991, pages 276-277). It will be understood that all such tautomeric forms are embraced by the present invention.
Unless otherwise specified alkyl, alkoxy and alkylthio groups have from one to six (preferably one to four) carbon atoms, alkenyl groups have from two to six (preferably two to four) carbon atoms and alkynyl groups have from three to six (preferably three or four) carbon atoms.
