Book Description
Novel carbon allotropes, such as spherical fullerenes and nanotubes, have been added, in the last three decades, to the traditionally recognised diamond and graphite. Although fullerene C60 has been speculated about for a long time. A fullerene is, according to a classical definition, an all-carbon molecule consisting entirely of pentagons (exactly 12) and hexagons (n/2-10). Non-classical fullerene extensions to include rings of other sizes have been considered. Fullerenes are commonly synthesised by arc-discharge or laser ablation methods. Spherical fullerenes became nowadays parts of real chemistry: they can be functionalised or inserted in supramolecular assemblies.

Book Description
New Edition! Completely Revised and Updated Chemical Graph Theory, 2nd Edition is a completely revised and updated edition of a highly regarded book that has been widely used since its publication in 1983. This unique book offers a basic introduction to the handling of molecular graphs - mathematical diagrams representing molecular structures. Using mathematics well within the vocabulary of most chemists, this volume elucidates the structural aspects of chemical graph theory: (1) the relationship between chemical and graph-theoretical terminology, elements of graph theory, and graph-theoretical matrices; (2) the topological aspects of the Hückel theory, resonance theory, and theories of aromaticity; and (3) the applications of chemical graph theory to structure-property and structure-activity relationships and to isomer enumeration. An extensive bibliography covering the most relevant advances in theory and applications is one of the book's most valuable features. This volume is intended to introduce the entire chemistry community to the applications of graph theory and will be of particular interest to theoretical organic and inorganic chemists, physical scientists, computational chemists, and those already involved in mathematical chemistry.

Book Description
The principal idea of this volume is to offer a Capita Selecta of unconventional and thought-provoking topics in organometallic chemistry, presented by experts in each field. As intended, this approach leads either to reviews covering a specific uncommon class of organometallic compounds or to overviews which relate uncommon physical properties with various classes of organometallic compounds. The contributions are streamlined thus onto two main axes - unusual properties reflecting structures and bonding situations, on the one hand, and uncommon structural features or structure-reactivity relationships, on the other. Extensive cross-referencing of useful information is provided, making this volume accessible for people working in rather different areas of organometallic chemistry. The synthesis of molecules with 'extreme' properties is a challenge for all those working in organometallic chemistry, irrelevant of theoretical/computational, synthetic or application interests. This book presents case studies at the interface of these overlapping interests. Unusual Structures and Physical Properties in Organometallic Chemistry: * Provides test cases for computational and theoretical models * Presents a challenge for synthetic chemists * Provides ideal show cases for analytical techniques This volume will be an invaluable reference for researchers in organometallic chemistry, computational and theoretical chemistry, NMR and other spectroscopic methods.

Book Description
"The second step is to determine constitution, Le. which atoms are bonded to which and by what types of bond. The result is ex pressed by a planar graph (or the corresponding connectivity mat rix) •••• In constitutional formulae, the atoms are represented by letters and the bonds by lines. They describe the topology of the molecule." VLADIMIR PRELOG, Nobel Lecture, December l2;h 1975. In the present notes we describe the topological approach to the che mistry of conjugated molecules using graph-theoretical concepts. Con jugatedstructures may be conveniently studied using planar and connec ted graphs because they reflect in the simple way the connectivity of their pi-centers. Connectivity is important topological property of a molecule which allows a conceptual qualitative understanding, via a non numerical analysis, of many chemical phenomena or at least that part of phenomenon which depends on topology. This would not be possible sole ly by means of numerical (molecular orbital) analysis.

Book Description
Studies in Natural Products Chemistry, Volume 14: Stereoselective Synthesis, Part I is a collection of discourses on the stereoselective synthesis of the anticancer anthrucycline antibiotics; tetramic acid antibiotics; 3-and 4-deoxyhexoses; polysaccharides; levoglucosenone as precursor to natural products; synthesis of oligoribonucleotides; and oxidation of guaiazulene. This volume deals with a broad range of natural products focusing on the synthesis of antibiotics and anticancer agents — anthracyclines, tetramic acid, taxodione, vinblastine, and vincristine. These aforementioned drugs are used for the treatment of cancer (anthracyclines) and Hodgkin's disease and childhood acute leukemia (vinblastine and vincristine). The importance of the latest developments in the stereocontrolled synthesis of polysaccharides is discussed as polysaccharides play a fundamental role in cell life and have many technical applications. The synthesis of bioactive carbohydrates 3- and 4-deoxy-hexoses is compared with the more occurring deoxyhexoses in nature such as the 2-deoxy, 6-deoxy, and 2,6-dideoxy-hexoses, because the former are rare compounds and useful tools in the study of biological and biochemical properties of mono- and oligosaccharides, glycoproteins, and antibiotics. Alkaloids derived from Apocynaceae are known for their medicinal properties; hence the synthetic approaches to vinblastine and vincristine are discussed. Because of the minute amounts available from herbal sources, efforts toward their chemical synthesis are given more reference. This book can be a useful reference for the organic chemists. Chemical researchers, pharmaceutical scientists, and professionals of bioorganic chemistry will likewise gain a lot from this collection.

Book Description
Even high-speed supercomputers cannot easily convert traditional two-dimensional databases from chemical topology into the three-dimensional ones demanded by today's chemists, particularly those working in drug design. This fascinating volume resolves this problem by positing mathematical and topological models which greatly expand the capabilities of chemical graph theory. The authors examine QSAR and molecular similarity studies, the relationship between the sequence of amino acids and the less familiar secondary and tertiary protein structures, and new topological methods.
