Cluster Chemistry. XCV. Some More Chemistry of Ru₃(μ-dppm )(CO)₁₀: Reactions With Allyl Bromide, Dimethyl Disulfide and AuCl(PPh₃), and Preparation of Some Complexes Containing Tertiary Phosphines and Phosphites. X-Ray Structure of Ru₃(μ-H)(μ-SMe)(μ-dppm)(CO)₈

Abstract

Reactions between Ru₃(μ-dppm )(CO)₁₀ and several reagents have been studied. With allyl bromide, cluster breakup occurs to give binuclear Ru₂(μ-Br)(μ-C₃H₅)(μ- dppm )(CO)₄. With Me₂S₂, binuclear Ru₂(μ- SMe )₂(μ- dppm )(CO)₄ and trinuclear Ru₃(μ-H)(μ- SMe )(μ- dppm )(CO)₈ are obtained; the X-ray structure of the latter has been determined. With AuCl (PPh₃), addition to one Ru-Ru bond gives AuRu₃(μ- Cl )(μ- dppm )(CO)₈(PPh₃). Some data on tertiary phosphine substituted products formed in reactions with PMe₃, PPh₃, P(C₆H₄Me-3)₃, P(C₆H₄Me-4)₃, P( OMe )₃, P(OCH₂CF₃)₃, dppe and Fe(η-C₅H₄PPh₂)₂ are also given.
