Book Synopsis Transition Metal Carbonyl Cluster Chemistry by : Paul J. Dyson
Download or read book Transition Metal Carbonyl Cluster Chemistry written by Paul J. Dyson and published by CRC Press. This book was released on 2000-11-17 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal carbonyl clusters (TMCCs) continue to inspire great interest in chemical research, as much for their fascinating structures as for potential industrial applications conferred by their unique properties. This highly accessible book introduces the bonding, structure, spectroscopic properties, and characterization of clusters, and then explores their synthesis, reactivity, reaction mechanisms and use in organic synthesis and catalysis. Transition Metal Carbonyl Cluster Chemistry describes models and rules that correlate cluster structure with electron count, which are then applied in worked examples. Subsequent chapters explain how bonding relates to molecular structure, demonstrate the use of spectroscopic techniques such as NMR, IR and MS in cluster chemistry, and outline the factors contributing to the stability, dynamics and reactivity of clusters. The second part of this book discusses the synthesis and applications of TMCCs. It emphasizes the differences between the reactivities of clusters vs. mononuclear metal complexes, contingent to the availability of multiple-bonding sites and heterosite reactivity. The final chapters discuss reactions in which clusters act as homogeneous catalysts; including discussion on the use of solid and biphasic liquid-liquid supported clusters in heterogeneous catalysts. A useful reference for those commencing further research or post-graduate study on metal carbonyl clusters and advanced organometallic chemistry, this book is also a cornerstone addition to academic and libraries as well as private collections.
Book Synopsis Metal Clusters in Catalysis by : Bruce C. Gates
Download or read book Metal Clusters in Catalysis written by Bruce C. Gates and published by Elsevier Publishing Company. This book was released on 1986 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on metal clusters (compounds with metal-metal bonds) has undergone explosive growth and the subject is now perhaps one of the hottest'' topics in organometallic chemistry. The prospect of catalytic applications has motivated a large part of the research mentioned in this book - the long term goal being to exploit the unique properties of metal clusters to prepare catalysts with new activities and selectivities. This is the first book to address the role of metal clusters in catalysis. The coverage is up-to-date and is particularly comprehensive, ranging from molecular chemistry of clusters (synthesis, structure, thermochemistry, reactivity, and homogeneous catalysis) to supported clusters (molecular analogues on polymers, and metal oxides and metals in zeolite cages). Preparation by methods of organometallic surface chemistry and metal atom chemistry and characterization of surface structures by physical methods are highlighted. Concepts unifying metal cluster chemistry and the chemistry of metal surfaces are elucidated. Of particular value to the user will be the cluster and subject indexes. The cluster index is organized in alphabetical order according to the metal.

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

Available in PDF, EPUB and Kindle. Book excerpt: This book has been conceived to collect the most important recent advances in all areas of hydride chemistry research, including chemical reactivity, instrumental investigation, theory, and applications in the areas of catalysis, biochemistry and materials science. Many of the chapters have been written by the plenary lecturers of the EURO-Hydrides 2000 conference, but other leading scientists in this field have also been invited to contribute. The first part of the book focuses on the chemistry and catalysis of transition metal hydrides. Another block of chapters illustrates the most recent advances in the application of instrumental techniques to the study of the properties and reactivity of hydride compounds. The final part of the book illustrates the relevance of metal-hydrogen bonds in biochemistry and materials science. All of the chapters of this book have been evaluated by independent reviewers.
