Book excerpt: This concise introduction to boranes and metalloboranes employs an informal and straightforward style. The author establishes facts first, and rationalization and theories follow. Ideas of cluster bonding are presented, and the author surveys different approaches to the bonding in clusters, emphasizing the use of frontier molecule orbitals and the construction of clusters from fragments. The application of spectroscopic techniques to the elucidation of cluster structure is discussed, with an emphasis on multinuclear NMR spectroscopy. The second edition includes an update on structural data for boranes and their anions. Sections on spectroscopy and the reactivity of metalloboranes have been slightly expanded and references have been updated.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular clusters, in the broad sense that the term is commonly understood, today comprise an enormous class of species extending into virtually every important area of chemistry: "naked" metal clusters, transition metal carbonyl clusters, hydrocarbon cages such as cubane (C H ) and dodecahedrane (C H ), 8 8 20 20 organometallic cluster complexes, enzymes containing Fe S or MoFe S 4 4 3 4 cores, high polymers based on carborane units, and, of course, the many kinds of polyhedral borane species. So large is the area spanned by these diverse classes that any attempt to deal with them comprehensively in one volume would, to say the least, be ambitious-and also premature. We are presently at a stage where intriguing relationships between the various cluster families are becoming apparent (particularly in terms of bonding descriptions), and despite large dif ferences in their chemistry an underlying unity is gradually developing in the field. For example, structural changes occurring in Fe S cores as electrons are 4 4 pumped in and out, in some measure resemble those observed in boranes and carboranes. The cleavage of alkynes via incorporation into carborane cages and subsequent cage rearrangement, a sequence familiar to boron chemists, is a thermodynamically favored process which may be related to the behavior of unsaturated hydrocarbons on metal surfaces; analogies of this sort have drawn attention from theorists and experimentalists.
Download or read book Nuclear Magnetic Resonance Spectroscopy of Boron Compounds written by Heinrich Nöth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The revolutionary impetus of the NMR methods in organic chemistry has parallels in the field of boron chemistry. lIB NMR spectroscopy provided a basis for the elucida tion of structures and reactions of the boron hydrides. However, although many studies have been carried out with the higher boranes, carboranes, metalloboranes, etc. , and although certain patterns have emerged, the correlation between the observed chemical shift and the assigned structural unit is still not fully understood. Therefore, predictions in this area are still rather limited, and semiquantitative interpretations are not yet pos sible. Several years ago Eaton and Lipscomb sUpImarized the status in this field in their book "NMR Studies of Boron Hydrides and Related Compounds" and a plethora of new data has accumulated since then. The book also contained material on simple bo rane derivatives, but they were not discussed in any detail. On the other hand many systematic studies, both synthetic and spectroscopic, have been conducted on these simple boron materials in the last decade. Thus a large amount of NMR information is available, not only on lIB but also on 1 H, 1 3 C, and 14 N. However, this information is widely scattered in the literature, and often the data are not discussed at all. It see med appropriate, therefore, to collect these data and to present them in one volume.

Download or read book Metal Complexes Containing Boron Based Ligands written by Gareth Owen and published by MDPI. This book was released on 2019-10-30 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron-based compounds have been utilized as ligands within transition metal complexes for many decades. The diversity of such compounds in terms of varying functional groups is truly exceptional. Boron compounds are of high interest due to the great potential to modify the substituents around the boron center and to produce a broad range of structural motifs. The many different ways these compounds can coordinate or interact with transition metal centers is astonishing. Examples of transition metal complexes containing boron-based ligands include scorpionates, cluster-type borane- and carboranes, borates, and phosphine-stabilized borylene ligands. This Special Issue brings together a collection of articles focusing on recent developments in the aforementioned boron-based ligands. The articles reported in this book will provide the reader with an overview of the types of boron-based ligands which are currently being researched in groups around the world.

Download or read book Organometallic Reactions and Syntheses written by E. I. Becker and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary literature on organometallic chemistry has undergone phenomenal growth. The number of papers published from 1951 to 1976 is about equal to all prior literature. Together with this intense activity there has developed a complexity in the literature. Thus, specialized texts and teaching texts, a review journal, an advanced series, and a research journal have all appeared during this period. The present series also reflects this growth and recognizes that many categories of organometallic compounds now have numerous representatives in the literature. The purpose of Organometallic Reactions and Syntheses is to provide complete chapters on selected categories of organometallic compounds, describing the methods by which they have been synthesized and the reactions they undergo. The emphasis is on the experimental aspects, although struc tures of compounds and mechanisms of reactions are discussed briefly and referenced. Tables of all of the compounds prepared in the category under consideration and detailed directions for specific types make these chapters particularly helpful to the preparative chemist. While the specific directions have not been referenced in the same way. as are those in Organic Syntheses and Inorganic Syntheses, the personal experiences of the authors often lend special merit to the procedures and enable the reader to avoid many of the pitfalls frequently encountered in selecting an experimental procedure from the literature.

This book was released on 2013-03-09 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Friday, February 20, 1980, I had the pleasure to be present at the inaugural lecture of my colleague Jan Reedijk, who had just been named at the Chair of Inorganic Chemistry of Leiden University. According to tradition, the ceremony took place in the impressive Hall of the old University Academy Building. In the course of his lecture, Jan mentioned a number of recent developments in chemistry which had struck him as particularly important or interesting. Among those was the synthesis of large metal cluster compounds, and, to my luck, he showed a slide ofthe molecular structure of [PtI9(C)b]4-. (To my luck, since at traditional Leiden University it is quite unusual to show slides at such ceremonies.) This constituted my first acquaintance with this exciting new class of materials. I became immediately fascinated by this molecule, partly because of the esthetic beauty of its fivefold symmetry, partly because as a physicist it struck me that it could be visualized as an "embryonically small" metal particle, embedded in a shell of CO ligands.
