Abstract: Abstract of thesis entitled THE CHEMISTRY OF MIXED-METAL CLUSTERS OF OSMIUM AND RHODIUM Submitted by LAU PO KWAN JASMINE for the degree of Doctor of Philosophy at The University of Hong Kong in December 2005 The general background of metal clusters, the chemistry of osmium-rhodium mixed-metal clusters, and their potential catalytic applications are reviewed. The work in the synthesis, characterizations, and reactivity studies of different series of osmium-rhodium mixed-metal clusters help us to understand the properties and reactivities of new clusters as compared to the bulk metal surface. 1 1 1 A novel face-capping mode of toluene was observed in [Os Rh (μ -η η η - 3 4 3 C H CH )(CO) ] 1. Cluster 1, together with [Os Rh(-H)(η -C H CH )(CO) ] 2 6 5 3 13 4 6 5 3 12 and a known compound [Os Rh (η -C H CH )(-CO)(CO) ], were obtained from 5 2 6 5 3 16 the reaction of [Os Rh(μ-H) (CO) ] with toluene in the presence of an excess 3 3 12amount of 4-vinylphenol. The reaction of [Os Rh(-H) (CO) ] with an excess 3 3 12 amount of 4-vinylphenol (as a hydride acceptor) in refluxing m-xylene, chlorobenzene, or benzene yielded three new clusters [Os Rh {η -C H (CH ) } 5 2 6 4 3 2 6 6 (-CO)(CO) ] 3, [Os Rh (η -C H Cl)(-CO)(CO) ] 4, and [Os Rh (η -C H ) 16 5 2 6 5 16 5 2 6 6 (-CO)(CO) ] 5, respectively. 16 The hydrogenation of [Os Rh (η -C H CH )(-CO)(CO)] with 5 2 6 5 3 16 [Os (-H) (CO) ] resulted in moderate yields of two hydrogen-rich compounds: 3 2 10 [Os Rh (-H) (CO) ] 6 and [Os Rh Cl(-H) (CO) ] 7. The reaction of 7 3 11 23 5 3 8 18 [Os Rh (η -C H CH )(-CO)(CO) ] with hydrogen yielded a new cluster 5 2 6 5 3 16 compound, [Os Rh(-H) (CO) ] 8. A deuterium exchange experiment was 5 5 18 performed on 6, and 7. Both the compounds proved to be able to exchange the H atom with D in the presence of D SO, and the absence of the hydride signal in the 2 4 H NMR spectrum is consistent with this. Therefore, clusters 6 and 7 may serve as appropriate new hydrogen storage models. A detailed discussion of the chemistry of anionic osmium-rhodium mixed-metal clusters with Au cationic fragments using [Au(PPh )Cl] and [(AuCl) L-L], where L 3 2 = dppe (bis(diphenylphosphino)ethane) or dppp (bis(diphenylphosphino)propane), is presented. Two mono-anionic osmium-rhodium mixed-metal clusters [PPN][Os Rh(μ-CO)(CO) ] 9 and [PPN][Os Rh (μ-CO) (CO) ] 10 were prepared 6 19 9 3 2 26 by the thermolysis of [Os Rh(μ-H) (CO) ]. Electrochemistry studies on 10 showed 3 3 12 four successive redox couples, and revealed a novel electron reservoir property. Treatment of 9 with two equivalent of [Au(PPh)Cl] gave compounds [Os Rh Au(CO) (PPh )] 11, and [Os Au (CO) (PPh ) ][Os Rh(μ-CO)(CO) ] 12. 4 3 18 3 5 3 15 3 3 6 19 Both compounds successfully demonstrated the introduction of the Au(PR ) units 3into transition-metal clusters. Two linked clusters [{Os RhAu(μ-CO)(CO) } (dppp)] 6 19 2 13 and [{Os RhAu(μ-CO)(CO) } (dppe)] 14 were prepared by the reaction of 9 6 19 2 with two equivalent [(AuCl) dppp] and [(AuCl) dppe], respectively. 2 2 The synthesis and characterization of linked cluster [{Os (CO) (μ -H)} 3 10 2 2 {μ,μ -NC H C H N}] 15 from the reaction of [Os Rh(μ-H) (CO) ] with aniline in 2 2 6 4 6 4 3 3 12 the presence of an excess amount of 4-vinyl phenol

Book Synopsis Organometallic Chemistry by : M Green
Download or read book Organometallic Chemistry written by M Green and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organometallic chemistry is an interdisciplinary science which continues to grow at a rapid pace. Although there is continued interest in synthetic and structural studies the last decade has seen a growing interest in the potential of organometallic chemistry to provide answers to problems in catalysis synthetic organic chemistry and also in the development of new materials. This Specialist Periodical Report aims to reflect these current interests reviewing progress in theoretical organometallic chemistry, main group chemistry, the lanthanides and all aspects of transition metal chemistry. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book Synopsis Metal Clusters in Chemistry by : Pierre Braunstein
Download or read book Metal Clusters in Chemistry written by Pierre Braunstein and published by Wiley-VCH. This book was released on 2000-01-11 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal cluster chemistry is at the cutting edge between molecular and solid-state chemistry and has therefore had a great impact on the researchers working on organic, coordination, and solid-state chemistry, catalysis, physics, and materials science. The development of new sophisticated synthetic techniques has led to enormous progress in the synthesis of this diverse class of compounds. The number of clusters is growing rapidly, since the possible variations in the metal and ligand sphere are numerous. Modern bonding theories, such as the isolobal principle, have allowed a better understanding of the structures and properties of metal clusters, and thus paved the way for the usage of these versatile materials. Catalysis and nanomaterials are just two of the very promising application-oriented fields. Seventy six contributions, written by world experts in this research field, provide extensive coverage of different aspects of cluster chemistry, ranging from synthesis, structure determination, and dynamics to applications. Up-to-date information, including an impressive collection of structural data and illustrations, extensive coverage of the most important publications of the last decade, and many more features make this three-volume set a complete single-source guide for all researchers working in the area of cluster chemistry.
