PESTICIDALLY ACTIVE PYRAZOLE DERIVATIVES

Compounds of formula (I), as defined herein, to processes for preparing them, to pesticidal, in particular insecticidal, acaricidal, molluscicidal and nematicidal compositions comprising them and to methods of using them to combat and control pests such as insect, acarine, mollusc and nematode pests.

PREPARATION OF COMPOUNDS WITH A PERFLUOROALKYLSULFONYL GROUP

Sulfuryl fluoride is reacted with a perfluoroalkene continuously, for example, under a pressure of up to 2 bars (abs), to form a sulfonyl fluoride or a sulfone. A preferred perfluoroalkene is hexafluoropropene which can be reacted with sulfuryl fluoride to form perfluoroisopropylsulfonyl fluoride.

Process for the synthesis of fluorinated alkyl sulphonyl halides

Preparation of fluorinated alkyl sulphonyl halides having the general formula: STR1 where RIf is fluorinated alkyl group and RIIf is a fluorinated alkyl group or fluorine, X is a halogen atom, and Y is a proton, a halogen atom, or a fluorinated alkyl groups, by reaction of a corresponding fluorinated unsaturated hydrocarbon with sulphuryl halide, wherein the reaction is carried out in the presence of at least catalytic amounts of a fluoride in a solvent comprising compounds having one or more SO and/or SO2 groups incorporated in the compound structure.
