Download or read book Transition Metal Carbonyl Cluster Chemistry written by Paul J. Dyson and published by CRC Press. This book was released on 2018-10-03 with total page 180 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.

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 Comprehensive Organometallic Chemistry II, Volume 7 by : D.F. Schriver
Download or read book Comprehensive Organometallic Chemistry II, Volume 7 written by D.F. Schriver and published by Elsevier. This book was released on 2002-09-10 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: The section devoted to iron in this volume reflects the tremendous progress in the area. Specifically cluster chemistry, ligand transformations and detailed structural results are more prominent in COMC II. The organic chemistry of ruthenium and osmium is an area which has burgeoned during the period since the publication of COMC. This is especially true for the cluster chemistry of these elements, which have provided most of the advances in this important field. Consequently, this volume will include an update (1981-1993) of the chemistry of mono- and bi-nuclear complexes of ruthenium and osmium, with a rather more extensive treatment of tri- and tetra-nuclear complexes. This is because many of the early results in ruthenium and osmium cluster chemistry described in COMC are now much better understood and can thus be placed in a more general context. In the case of complexes containing clusters with five or more metal atoms, the coverage is essentially complete, again because this chemistry has developed during the 1980s.
