Abstract

Addition of RLi (R = Ph, Me) to [Ru₆C(CO)₁₄(η⁶-C₆H₆)] (1) or [Ru₆C(CO)₁₂(η₆-C₆H ₆)(μ₂-η²:η²-C ₆H₈)] (2), followed by reaction with [AuPPh₃Cl]/TlPF₆, leads to the formation of the mixed ruthenium-gold cluster complexes [Ru₆C(CO)₁₄(η⁴-C₆H ₆R₂) (AuPPh₃)₂] (5a, b) and [Ru₆C(CO)₁₂(η⁶-C₆H₅R) (μ₂-η²:η²-C₆H ₈) (AuPPh₃)] (6a, b), respectively. Treatment of the likely intermediate products, the cluster salts (PPN)₂[Ru₆C(CO)₁₄(η⁴-C ₆H₆R₂)] (3a, b) and (PPN)₂[Ru₆C(CO)₁₂(η⁵-C ₆H₆R)(μ₂-η²-C ₆H₈)] (4a, b) (PPN = [N(PPh₃)₂]^-) with [CPh₃] [BF₄] affords hydride abstraction and gives the substituted arene cluster complexes [Ru₆C(CO)₁₄(η⁶-C₆H ₄R₂)] (7a, b) and [Ru₆C(CO)₁₂(η⁶-C₆H ₅R)(μ₂-η²:η²-C ₆H₈)] (8a, b), respectively. The crystal and molecular structures of [Ru₆C(CO)₁₄(η⁶-C₆H ₄Ph₂)] (7a) and of two polymorphs of [Ru₆C(CO)₁₄(η⁶-C₆H ₄Me₂)] (7b) are established by X-ray crystallography. The molecules have a p-terphenyl (7a) and a p-xylene (7b) ligand η⁶-coordinated to a vertex of a Ru₆ octahedron.
