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.

This book was released on 1991 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The cluster anion ($\rm Re\sb7C(CO)\sb{21}Ir(C\sb8H\sb{14})(CO)\rbrack \sp{2-}$ has been synthesized by the capping of ($\rm Re\sb7C(CO)\sb{21}\rbrack \sp{3-}$ with the in-situ generated cationic species from the reaction of ($\rm Ir(C\sb8H\sb{14})\sb2(CO)Cl\rbrack \sb2$ and AgBF$\sb4.$ This new heptarhenium-iridium compound reacts with two electron donors to give ligand-substituted compounds ($\rm Re\sb7C(CO)\sb{21}Ir(L)(CO)\rbrack \sp{2-}$ (L = CO, $\rm C\sb2H\sb4,$ PMePh$\sb2,$ and PPh$\sb3),$ and with triphenylsilane and allyl bromide to form the oxidative addition products ($\rm Re\sb7C(CO)\sb{21}Ir(H)(CO)(SiPh\sb3)\rbrack \sp{2-}$ and ($\rm Re\sb7C(CO)\sb{21}Ir(\eta\sp3C\sb3H\sb5)(CO)\rbrack \sp-.$ The reactivities at iridium parallel those of the indenyl complex $\rm (\eta\sp5C\sb9H\sb7)Ir(C\sb8H\sb{14})(CO),$ thus giving further support for the previously proposed analogy between ($\rm Re\sb7C(CO)\sb{21}\rbrack \sp{3-}$ and the cyclopentadienyl ligand and its derivatives. Formulation and characterization of these new compounds are based on elemental analysis, IR, $\sp1$H and $\sp{13}$C NMR spectroscopies, fast-atom bombardment mass spectrometry, and X-ray crystallography. The cluster anion ($\rm Re\sb7C(CO)\sb{21}Ir(CO)\sb2\rbrack \sp{2-}$ undergoes an irreversible framework isomerization process in solution to form a new isomer $\rm \{\lbrack Re(CO)\sb3\rbrack\sb2\lbrack Re\sb5IrC(CO)\sb{17}\rbrack \}\sp{2-}.$ Kinetic studies have been carried out, and a reaction mechanism has also been proposed. In refluxing acetonitrile $\rm \{\lbrack Re(CO)\sb3\rbrack\sb2\lbrack Re\sb5IrC(CO)\sb{17}\rbrack \}\sp{2-}$ loses a Re(CO)$\sb3\sp+$ fragment, leading to the formation of $\rm \lbrack Re\sb6IrC(CO)\sb{20}\rbrack \sp{3-}.$ This analog of $\rm \lbrack Re\sb7C(CO)\sb{21}\rbrack \sp{3-}$ reacts with Au(PPh$\sb3)$Cl to give ($\rm Re\sb6IrC(CO)\sb{20}Au(PPh\sb3)\rbrack \sp{2-}$ and $\rm \{Re\sb6IrC(CO)\sb{20}\lbrack Au(PPh\sb3)\rbrack \sb2\}\sp-,$ which have been characterized by $\sp{31}$P and $\sp{13}$C NMR studies. The known cluster anion ($\rm Ru\sb{10}C\sb2(CO)\sb{24}\rbrack \sp{2-}$ can be prepared via an alternative route involving the redox condensation of ($\rm Ru\sb6C(CO)\sb{16}\rbrack \sp{2-}$ and Ru$\sb5$C(CO)$\sb{15}.$ Substitution of two apical carbonyls in ($\rm Ru\sb{10}C\sb2(CO)\sb{24}\rbrack \sp{2-}$ by one diphenylacetylene molecule gives the compound ($\rm Ru\sb{10}C\sb2(CO)\sb{22}(C\sb2Ph\sb2)\rbrack \sp{2-},$ which contains a new ruthenium-ruthenium bond between the two apical atoms in the bioctahedral structure. Carbonyl ligand dynamic exchange behavior has been observed by variable-temperature $\sp{13}$C NMR spectroscopy.

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.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In past years bimetallic nanoparticle catalysts have been shown to exhibit superior catalytic properties, due to the presence of different metals such that one metal performs a certain role in a catalytic cycle and the other performs another function. Our goal was to synthesize bimetallic cluster complexes containing cheap metals for the application in heterogeneous catalysis. We have reported the reaction of Fe5(C)(CO)15 with Ni(COD)2, in acetonitrile solvent to afford the nickel-iron complex NiFe5(C)(NCMe)(CO)15. In addition, some chemistry with this compound was studied which gave new Fe-Ni carbide clusters with varying Fe-Ni ratios. Similar chemistry was observed with the reaction of Ru5(C)(CO)15 with Ni(COD)2. Electronic unsaturation in transition metal complexes is induced by bulky ligands. The bulky ligands shield the metal center from the approach of large molecules, leaving enough room for the selective approach of small molecules. Bulky ligands such as phosphines, stananes, germanes and N-heterocyclic carbenes stabilize the reactive intermediates of transition metal complexes. Based on this approach, we have synthesized Ru-Ge cluster complexes from the reaction of bulky tertiary butyl germane, ButGeH3 with ruthenium carbonyl complexes. We have also synthesized Ru-Pt bimetallic transition metal cluster complexes with bulky N-heterocyclic carbene ligand. All the new compounds were structurally characterized by single-crystal X-ray diffraction analyses.

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 495 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.
