Ruthenium complexes of the formula I or IVwhereX, Y are anionic ligands,R is hydrogen or a substituted or unsubstituted C1-C20-alkyl radical or C6-C20-aryl radical andL1 and L2 are, independently of one another, uncharged electron donor ligands, are prepared by(a) reaction of RuX3 with L1 and L2 in an inert solvent in the presence of a reducing agent and hydrogen and(b) reaction with compounds of the formula IIwhere R is as defined above, in the presence or absence of water, and, if desired after isolation of the intermediate, with HY, [HL1]Y or [HL2]Y. |
