Abstract

Reaction of [PPh₄][Ru₁₀(μ,-H)(μ₆-C)(CO)₂₄] (1a) with two equivalents of trimethylphosphite at room temperature gives a mixture of the mono-(2a), bis-(3a), tris-(4a) and tetrakis-(5a) phosphite-substituted cluster anions [Ru₁₀(μ-H)(μ₆-C)(CO)_24-x{P(OMe)₃}_x]^- (x = 1-4). Reaction of [Ru₂(μ-H)(μ-NC₅H₄)₂(CO)₄(NC₅H₅)₂][Ru₁₀(μ-H)(μ₆-C)(CO)₂₄] (1b) with ten equivalents of trimethylphosphite at room temperature gives the tetrakis-substituted anion [Ru₁₀(μ-H)(μ₆-C)(CO)₂₀{P(OMe)₃}₄]^- as its [Ru₂(μ-H)(μ-NC₅H₄)₂(CO)₄{P(OMe)₃}₂]⁺ salt (5c). Cluster 3a has been characterized by an X-ray structural study, which confirms that the phosphite ligands occupy apical sites in these clusters. Reaction of [Ru₁₀(μ-H)(μ₆-C)(CO)₂₄]^- with 20 equivalents of trimethylphosphite in refluxing acetone leads to tetradecapping of the decaruthenium core and formation of Ru₆(μ6-C)(CO)₁₃{P(OMe)₃}₄ (6). Reaction of 1b with 0.5 equivalents of bis(diphenylphosphino)acetylene gives the linked icosaruthenium cluster dianion [{Ru₁₀(μ-H)(μ₆-C)(CO)₂₃}₂(μ-Ph₂PC≡CPPh₂)]^2- (7b); heating 7b leads to loss of the phosphine rather than ligand-assisted condensation.
