Abstract: front page image
(EN)Disclosed are cationic ruthenium arene complexes of Formula (I): [Ru(D-Z1-NHR1)(Ar)(LB)n]r+[Y-]r wherein Ar is optionally substituted aryl, D-Z1-NHR1 is a coordinated bidentate ligand wherein D, Z1, R1 and R2 are as defined herein, and where R1 and Ar, or R2 and Ar may be linked together, n is 0 or 1, r is 1 or 2, LB is a neutral Lewis base, and Y is a non-coordinating anion. The complexes are active catalysts for reduction reactions, including the transfer-hydrogenation of carbon-oxygen (C=O) and carbon-nitrogen (C=N) double bonds.
(FR)L'invention concerne des complexes arène-ruthénium cationiques représentés par la formule I, [Ru(D-Z1-NHR1)(Ar)(LB)n]I+[Y-]r dans laquelle Ar est éventuellement substitué aryle, D-Z1-NHR1 est un ligand bidentate coordonné dans lequel D, Z1, R1 et R2 sont tels que définis dans la description, et dans laquelle R1 et Ar, ou R2 et Ar peuvent être liés ensemble, n est 0 ou 1, r est 1 ou 2, LB est une base de Lewis neutre, et Y est un anion de non coordination. Les complexes sont des catalyseurs actifs pour des réactions de réduction, notamment l'hydrogénation par transfert de liaisons doubles carbone-oxygène (C=O) et carbone -azote (C=N).
