Abstract:
A process for preparing ruthenium complexes of the formula IRuX.sub.2 (.dbd.CH--CH.sub.2 R)L.sup.1 L.sup.2 (I)whereX is an anionic ligand,R is hydrogen or a substituted or unsubstituted C.sub.1 -C.sub.20 -alkyl radical or C.sub.6 -C.sub.20 -aryl radical andL.sup.1 and L.sup.2 are, independently of one another, uncharged electron donor ligands, by(a) reaction of RuX.sub.3 with L.sup.1 and L.sup.2 in an inert solvent in the presence of a reducing agent and hydrogen and, without isolation of intermediates,(b) subsequent reaction with compounds of the formula IIR--C.tbd.CH (II)where R is as defined above, in the presence or absence of water.
