CA 2419368

In ruthenium complexes of general formula A or B, X1, X2 independently represent single or multidentate anionic ligands; R, R', R'' independently represent hydrogen or optionally substituted C1-20-alkyl, C6-20-aryl or C7-20- alkylaryl radicals; and L1, L2 independently represent neutral electron donor ligands which are co-ordinated at the metallic centre as carboids, and which can be linked by a bridge W having 0 to 20 carbon atoms. Said bridge can be a constituent of a cyclic or aromatic group and can be split by heteroatoms, with the exception of C,N-heterocyclic five-membered ring systems.

Dans les complexes de ruthénium de la formule générale (A) ou (B), X?1¿ et X?2¿ représentent indépendamment des ligands anioniques à une ou plusieurs dents ; R, R', et R'' représentent indépendamment de l'hydrogène ou des restes C¿1-20?-alkyl, C¿6-20?-aryl, ou C¿7-20?-alkylaryl éventuellement substitués ; et, L?1¿ et L?2¿ représentent indépendamment des ligands neutres de donneurs d'électrons, coordonnés sur le centre métallique en tant que carbénoïdes, et pouvant être liés par un pont W portant de 0 à 20 atomes de carbone, ledit pont étant un constituant d'un groupe cyclique ou aromatique et pouvant être interrompu par des hétéroatomes, avec exception de systèmes pentacycliques C, N hétérocycliques.
