Available in PDF, EPUB and Kindle. Book excerpt: There are only few topics in organometallic chemistry, which have stimulated research activities in as many areas, as transition-metal carbene (alkylidene) complexes. About 25 years after the first planned synthesis of a carbene complex in E.O. Fischer's laboratory in Munich the NATO Advanced Research Workshop on Transition-Metal Carbene Complexes was the first meeting which,brought together scientists from different disciplines to discuss inorganic, organic, theoretical structural catalysis-related aspects of metal carbene chemistry. The 70th birthday of Professor E.O. Fischer was a good occasion for this enterprise. The organizers of the meeting (K.D. Dotz, Marburg; F.R. KreiBl, Munchen; U. Schubert, Wurzburg) were encouraged by the fact that most of the leading scientists in this area were able to participate in the workshop. The very high standard of the contributions is reflected in this book, which contains papers from the majority of the participants. The Proceedings show the state of the art in metal carbene chemistry and will hopefully be a landmark in the development of this area of chemistry. Generous financial support for the workshop and for the preparation of this book was provided by the Scientific Affairs Division of NATO and some companies. The organizers also acknowledge the efforts of the staff of the Bildungs zentrum der Hans-Seidel-Stiftung in Wild bad Kreuth for creating a pleasant and stimulating atmosphere during the conference.

Download or read book Organometallic Chemistry written by Ian J. S. Fairlamb and published by Royal Society of Chemistry. This book was released on 2011-06-16 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of critical reviews and perspectives focussing on specific aspects of organometallic chemistry interfacing with other fields of study are provided. For this volume, the critical reviews cover topics such as the activation of "inert" carbon-hydrogen bonds, ligand design and organometallic radical species. For example, Charlie O'Hara discusses how mixed-metal compounds may perform the highly selective activation of C-H bonds and, in particular, how synergic relationships between various metals are crucial to this approach. The chemistry of a remarkable series of air-stable chiral primary phosphine ligands is discussed in some depth by Rachel Hiney, Arne Ficks, Helge M3ller-Bunz, Declan Gilheany and Lee Higham. This article focuses on the preparation of these ligands and also how they may be applied in various catalytic applications. Bas De Bruin reports on how ligand radical reactivity can be employed in synthetic organometallic chemistry and catalysis to achieve selectivity in radical-type transformations. As well as highlighting ligand-centered radical transformations in open-shell transition metals, an overview of the catalytic mechanism of Co(II)-catalysed olefin cyclopropanation is given, showing that enzyme-like cooperative metal-ligand-radical reactivity is no longer limited to real enzymes. Valuable and informative comprehensive reviews in the field of organometallic chemistry are also covered in this volume. For example, organolithium and organocuprate chemistry are reviewed by Joanna Haywood and Andrew Wheatley; aspects in Group 2 (Be-Ba) and Group 12 (Zn-Hg) compounds by Robert Less, Rebecca Melen and Dominic Wright; metal clusters by Mark Humphrey and Marie Cifuentes; and recent developments in the chemistry of the elements of Group 14 - focusing on low-coordination number compounds by Richard Layfield. This volume therefore covers many synthetic and applied aspects of modern organometallic chemistry which ought to be of interest to inorganic, organic and applied catalysis fields.
Download or read book Organic Synthesis Using Transition Metals written by Roderick Bates and published by John Wiley & Sons. This book was released on 2012-04-30 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metals open up new opportunities for synthesis, because their means of bonding and their reaction mechanisms differ from those of the elements of the s and p blocks. In the last two decades the subject has mushroomed - established reactions are seeing both technical improvements and increasing numbers of applications, and new reactions are being developed. The practicality of the subject is demonstrated by the large number of publications coming from the process development laboratories of pharmaceutical companies, and its importance is underlined by the fact that three Nobel prizes have been awarded for discoveries in this field in the 21st Century already. Organic Synthesis Using Transition Metals, 2nd Edition considers the ways in which transition metals, as catalysts and reagents, can be used in organic synthesis, both for pharmaceutical compounds and for natural products. It concentrates on the bond-forming reactions that set transition metal chemistry apart from "classical" organic chemistry. Each chapter is extensively referenced and provides a convenient point of entry to the research literature. Topics covered include: introduction to transition metals in organic synthesis coupling reactions C-H activation carbonylative coupling reactions alkene and alkyne insertion reactions electrophilic alkene and alkyne complexes reactions of alkyne complexes carbene complexes h3- or p-allyl -allyl complexes diene, dienyl and arene complexes cycloaddition and cycloisomerisation reactions For this second edition the text has been extensively revised and expanded to reflect the significant improvements and advances in the field since the first edition, as well as the large number of new transition metal-catalysed processes that have come to prominence in the last 10 years – for example the extraordinary progress in coupling reactions using “designer” ligands, catalysis using gold complexes, new opportunities arising from metathesis chemistry, and C-H activation – without neglecting the well established chemistry of metals such as palladium. Organic Synthesis Using Transition Metals, 2nd Edition will find a place on the bookshelves of advanced undergraduates and postgraduates working in organic synthesis, catalysis, medicinal chemistry and drug discovery. It is also useful for practising researchers who want to refresh and enhance their knowledge of the field.
Download or read book Multimetal Complexes of Fischer Carbenes written by Daniela Ina Bezuidenhout and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fischer carbene complexes of the Group VI transition metals (Cr, Mo and W) containing at least two or three different transition metal substituents, all in electronic contact with the carbene carbon atom, were synthesized and studied both in solution and in the solid state. For the complexes of the type [M(CO)5{C(OR)R }], the substituents chosen included (hetero)aromatic (benzene or thiophene) rings ; -bonded to a chromium tricarbonyl fragment or ferrocene as the R -substituent, while the OR-substituent was systematically varied between an ethoxy or a titanoxy group, to yield the complexes 1 (M = Cr, R = Et, R = Fc), 2 (M = W, R = Et, R = Fc), 5 (M = Cr, R = TiCp2Cl, R = Fc), 6 (M = W, R = TiCp2Cl, R = Fc), 7 (M = Mo, R = TiCp2Cl, R = Fc), 12 (M = Cr, R = TiCp2Cl, R = 2-thienyl) and 13 (M = Cr, R = TiCp2Cl, R = [Cr(CO) 3 (? 6-phenyl)]). Direct lithiation of the ferrocene with n-BuLi/TMEDA at elevated temperatures, followed by the Fischer method of carbene preparation, also resulted, in most cases, in the formation of the novel biscarbene complexes with bridging ferrocen- 1,1 -diyl carbene ligands [-Fe{C5H4C(OEt)M(CO) sub>5}2] (3: M = Cr, 4: M = W) or the unusual bimetallacyclic bridged biscarbene complexes [{ -TiCp2O2-O, O }{ - Fe(C5H4)2-C, C }{CM(CO) 5}2] (8: M = Cr, 9: M = W, 10: M = Mo). It was attempted to prepare the mixed heteronuclear biscarbene complex 11 [W(CO) 5C{ -TiCp2O2- O, O }{ -Fe(C5H4)2-C, C }CCr(CO) 5], however the complex could not be fully characterized. The investigation was expanded to include Group VII transition metals Mn and Re, and using the same methodology, the manganese complexes isolated included [MnCp(CO2{C(OR)Fc}] (22: R = Et, 24: R = TiCp2Cl), 23 [- Fe{C5H4C(OEt)MnCp(CO) 2}2] and 25 [{ -TiCp2O2-O, O }{ - Fe(C5H4)2- C, C }[CMnCp(CO) 2}2]. The different reactivity of the binary dirhenium decacarbonyl precursor complex, compared to that of the Group VI complexes, resulted in the formation of a range of complexes. The target compounds [Re2 (CO) 9{C(OR)Fc}] (26: R = Et, 31: R = TiCp2Cl), 27 [-Fe{C5H4C(OEt)Re2 (CO) 9}2] and 33 [{ - TiCp2O2-O, O }{ -Fe(C5H4)2-C, C }[CRe2 (CO) 9}2] were isolated displaying a variety of different geometric isomers. In addition, acyl (30) and aldehyde (32) decomposition products, as well as hydrido (29), and hydrido acyl hydroxycarbene (34) complexes and the unique dichloro-bridged biscarbene complex (28) were also characterized. Most of these complexes displayed Re-Re bond breaking, and two probable mechanisms, either radical or ionic, were proposed involving either hydrogen transfer or protonation followed by hydrolysis. Finally, the structural features and their relevance to bonding in the carbene cluster compounds of the Group VI transition metals were investigated as they represent indicators of possible reactivity sites in multimetal carbene assemblies. The possibility of using DFT calculations to quantify the effect of metal-containing substituents on the carbene ligands was tested and correlated with experimental parameters by employing methods such as vibrational spectroscopy, molecular orbital analysis, and cyclic voltammetry. The best results were obtained from the cyclic voltammetric studies, where the localized metal centre's oxidation potential correlated to both the calculated HOMO energy, and the effect of both the heteroatom substituent and the (hetero)arene substituent, as well as different combinations of the above.
