摘要：
Ruthenium-alkylidene complexes are obtained by reacting ruthenium (III) compounds with neutral donor ligands in presence of hydrogen and a reducing agent, and then reacting the unisolated intermediate with an acetylene compound in presence of hydrogen. A process for the production of ruthenium complexes of formula RuX2(=CH-CH2R)LL (I), in which X = a monodentate anionic ligand; R = hydrogen or optionally substituted 1-20C alkyl or 6-20C aryl; L, L = neutral electron-donor ligands , comprises (a) reacting RuX3 with L and L in an inert solvent in presence of hydrogen and a reducing agent and then, without isolating intermediates, (b) reacting with compounds of formula R-C?=CH (II) in the presence of hydrogen.
