Reaction of cis-Ru(2-OAc)2(PPh3) 2 with two-electron donor ligands L results in the formation of complexes trans-[Ru(1-OAc)(2-OAc)L(PPh3) 2] (L = CO, NO+, CNtBu). Vinylidene complexes (L = C=CHR) may be prepared from the corresponding reaction with terminal alkynes HC=CR, and species containing hydroxyvinylidene ligands (L = C=CHCR1R 2{OH}) may be prepared from related reactions with propargyl alcohols HC=CCR1R2{OH}. Treatment of cis-Ru(κ2- OAc)2(PPh3)2 with ω-alkynols HC=C(CH 2)nOH (n = 2-4) results in the formation of oxacyclocarbene complexes [L = CCH2(CH2)nO]. An analysis of the spectroscopic data and the structural metrics (as determined by X-ray crystallography) of this series of complexes allows for the relative donor/acceptor properties of the ligand L to be evaluated. This comparison indicates that the vinylidene ligand behaves in a similar fashion to the isocyanide ligand. The complex cis-[Ru(2-OAc)2(PPh 3)2] acts as a precursor for the formation of the complexes trans-[Ru(1-OAc)(2-OAc)L(PPh3) 2] where L is a two-electron donor, σ-donor/π-acceptor ligand. The structural and spectroscopic data of these species provide insight into the relative electron demand of the ligands L.
