High-Nuclearity Ruthenium Carbonyl Cluster Chemistry. 2. Reaction of [Ru2(μ-H)(μ-NC5H4)2(CO)4(NC5H5)2][Ru10(μ-H)(μ6-C)(CO)24] with Triphenylphosphine

Abstract

The (hydrido)(carbido)decaruthenium cluster anion [Ru10(μ-H)(μ6-C)(CO)24]- reacts with triphenylphosphine in a stepwise manner to afford [Ru10(μ-H)(μ6-C)-(CO)24-xPPh3)]- (x = 1–4), with initial ligand displacement on the apical ruthenium associated with the hydride ligand and subsequent ligand substitution at the other apices; the location of the phosphine substituent of the monosubstituted cluster anion [Ru10(μ-H)(μ6-C)-(CO)23PPh3)]- has been confirmed by a single crystal X-ray diffraction study.
