CA 2326159

This invention concerns compounds of formula (I), stereochemically isomeric forms thereof, acid or base addition salts thereof, N-oxides thereof, or quaternary ammonium derivatives thereof, wherein the dotted line is an optional bond; X is a direct bond when the dotted line represents a bond, or X is hydrogen or hydroxy, when the dotted line does not represent a bond; R1, R2, R5 and R6 are each independently selected from hydrogen, halo, hydroxy, C1- 4alkyl, C1-4alkyloxy, -SO3H, and the like; R3 and R4 are each independently selected from hydrogen, halo, hydroxy, C1-4alkyl, C1-4alkyloxy, nitro, amino, cyano, trifluoromethyl, or trifluoromethoxy; <u>.....</u> L is a radical of formula (a-1), (a-2), (a-3), (a-4), (a-5), (a-6), (a-7), (a-8), (a-9), (a-10); wherein A1 is a direct bond or C1-6alkanediyl; A2 is C2-6alkanediyl; and R7 to R11 are hydrogen, C1-6alkyl, aminoC1-6alkyl and the like; having biocidal properties; their preparation, compositions containing them and their use as a biocide.

L'invention concerne des composés de formule (I), des formes stéréochimiques isomères de ceux-ci, des sels d'addition acide ou basique de ceux-ci, des N-oxydes de ceux-ci, ou des dérivés d'ammonium quaternaire de ceux-ci, la ligne pointillée désignant une éventuelle liaison; X représente une liaison directe lorsque ladite ligne pointillée désigne une liaison, ou X représente hydrogène ou hydroxy si cette ligne ne symbolise pas une liaison; R?1¿, R?2¿, R?5¿, et R?6¿ sont choisis indépendamment parmi hydrogène, halo, hydroxy, alkyle C¿1-4?, alkyloxy C¿1-4?, -SO¿3?H, et analogues; R?3¿ et R?4¿ sont choisis indépendamment parmi hydrogène, halo, hydroxy, alkyle C¿1-4?, alkyloxy C¿1-4?, nitro, amino, cyano, trifluorométhyle, ou trifluorométhoxy, ?<u>.....</u>¿ L représente un radical de formules (a-1), (a-2), (a-3), (a-4), (a-5), (a-6), (a-7), (a-8), (a-9), (a-10); dans lesquelles A?1¿ représente une liaison directe ou alkanediyl C¿1-6?; A?2¿ représente alkanediyl C¿2-6?; et R?7¿ à R?11¿ représentent hydrogène, alkyle C¿1-6?, alkyle C¿1-6? amino, et analogues. Les composés de cette invention présentent des propriétés biocides. L'invention concerne également la préparation de ces composés, les compositions qui les renferment, et leur utilisation comme produits biocides.
