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.
