Abstract

Addition of RLi (R = Ph, Me) to [Ru6C(CO)146-C6H6)] (1) or [Ru6C(CO)126-C6H 6)(μ222-C 6H8)] (2), followed by reaction with [AuPPh3Cl]/TlPF6, leads to the formation of the mixed ruthenium-gold cluster complexes [Ru6C(CO)144-C6H 6R2) (AuPPh3)2] (5a, b) and [Ru6C(CO)126-C6H5R) (μ222-C6H 8) (AuPPh3)] (6a, b), respectively. Treatment of the likely intermediate products, the cluster salts (PPN)2[Ru6C(CO)144-C 6H6R2)] (3a, b) and (PPN)2[Ru6C(CO)125-C 6H6R)(μ22-C 6H8)] (4a, b) (PPN = [N(PPh3)2]-) with [CPh3] [BF4] affords hydride abstraction and gives the substituted arene cluster complexes [Ru6C(CO)146-C6H 4R2)] (7a, b) and [Ru6C(CO)126-C6H 5R)(μ222-C 6H8)] (8a, b), respectively. The crystal and molecular structures of [Ru6C(CO)146-C6H 4Ph2)] (7a) and of two polymorphs of [Ru6C(CO)146-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.
