Patent

CA 2372963

The invention relates to substituted benzoylisoxazoles of general formula (I), wherein R1, R2, R3 and (R4) represent hydrogen or certain substituents, a single bond or alkanediyl (alkylene) and an optionally substituted 4-12 membered saturated or unsaturated monocyclic or bicyclic heterocyclic group containing 1-4 heteroatoms (up to 4 nitrogen atoms and optionally - alternatively or additively - an oxygen atom or a sulphur atom, or an SO group or an SO2 group) and additionally containing 1-3 oxo groups (C=O) and/or thioxo groups (C=S) as constituents in a heterocycle. The invention also relates to a method for the production and use thereof as herbicides.

L'invention concerne des benzoylisoxazoles substitués de formule générale (I), dans laquelle R?1¿, R?2¿, R?3¿ et (R?4¿) désignent l'hydrogène ou des substituants déterminés, une liaison simple ou un alcanediyle (alkylène), et un groupe hétérocyclique, monocyclique ou bicyclique, saturé ou insaturé, de 4 à 12 chaînons, éventuellement substitué, renfermant 1 à 4 hétéroatomes (jusqu'à 4 atomes d'azote et, le cas échéant, en variante ou en plus, un atome d'oxygène ou un atome de soufre, ou un groupe SO ou un groupe SO¿2?), et renfermant en outre un à trois groupes oxo (C=O) et/ou groupes thioxo (C=S) comme constituants de l'hétérocycle. L'invention concerne en outre un procédé de fabrication de ces composés et leur utilisation comme herbicides.
