Book excerpt: Unparalleled in the breadth and depth of its coverage of all important aspects, this book systematically treats the electronic and magnetic properties of stoichiometric and non-stoichiometric cobaltites in both ordered and disordered phases. Authored by a pioneer and a rising star in the field, the monograph summarizes, organizes and streamlines the otherwise difficult-to-obtain information on this topic. An introductory chapter sets forth the crystal chemistry of cobalt oxides to lay the groundwork for an understanding of the complex phenomena observed in this materials class. Special emphasis is placed on a comprehensive discussion of cobaltite physical properties in different structural families. Providing a thorough introduction to cobalt oxides from a chemical and physical viewpoint as a basis for understanding their intricacies, this is a must-have for both experienced researchers as well as entrants to the field.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Metalloporphyrins have been shown to catalyze many fundamental and practically important chemical transformations, some of which represent the first demonstrations of these catalytic processes. The most notable examples include an assortment of atom/group transfer reactions, such as oxene, nitrene, and carbene transfers. Atom/group transfer reactions allow for the direct conversion of abundant and inexpensive alkenes and alkanes into value-added functional molecules. Previous reports from our group have shown that cobalt-porphyrin based carbene and nitrene transfer reactions are some of the most selective and practical catalytic systems developed for cyclopropanation and aziridination. Backed by a family of D2-symmetric chiral cobalt porphyrins our group continues the development of stereoselective carbene and nitrene transfer reactions. Metal-catalyzed cyclopropanation of olefins with diazo reagents has attracted great research interest because of its fundamental and practical importance. The resulting cyclopropyl units are recurrent motifs in biologically important molecules and can serve as versatile precursors in organic synthesis. Supported by a family of D2-symmetric chiral cobalt porphyrins, we have demonstrated the use of succimidyl diazoacetate as carbene source for a highly diastereo- and enantioselective cyclopropanation process. The resulting cyclopropyl succinimdyl esters are highly reactive and serve as valuable synthons for generating cyclopropylcarboxamides. We have also developed the first cobalt-porphyrin based intramolecular cyclopropanation, which is able to produce the resulting bicyclic lactones in high yields and enantioselectivity. Nitrene transfer reactions are also an attractive route to produce biologically and synthetically important molecules such as amines and aziridines. Although much progress has been made in nitrene transfer reactions utilizing [N-(p-toluenesulfonyl) imino]phenyliodinane (PhI=NTs) the nitrene source suffers from several drawbacks. Consequently, there has been growing interest in developing catalytic nitrene transfer reactions using alternate nitrene sources. To this end, we have utilized arylsulfonyl azides as nitrene source to explore their use in the development of a cobalt-porphyrin catalyzed enantioselective aziridination system. The cobalt catalyzed process can proceed under mild and neutral conditions in low catalyst loading without the need of other reagents, while generating nitrogen gas as the only byproduct. We have also explored the use of arylsulfonyl azides as nitrene source in a cobalt-catalyzed intramolecular C-H amination process.
Download or read book Cluster Chemistry written by Guillermo Gonzalez-Moraga and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cluster chemistry is one of the recent, exciting areas of Inorganic Chemistry. The occurence of molecular clusters, like fullerene C60, constitutes a fundamental feature midway between the chemistry of isolated chemical compounds and that of the elements. Main features of the Cluster Chemistry of both main group and transition metal elements are treated in this book. The author highlights aspects releated to the synthesis, the structure, the special bonding and the reactivity of these species. The book is written as a textbook for senior undergraduate and postgraduate students. References in tables andillustrations permit the reader to reach relevant original information. Professor Gonzalez-Moraga fills a demand for a publication appropriate for dissemination and specially for teaching this exciting subject. From the Contents: Current Concepts in Modern Chemistry - Transition Metal Cluster Chemistry - Main Group-Transition Metal Mixed Clusters - Cluster Compounds of the Main Group Elements - Synthetic Analogues of the Active Sites of Iron-Sulfur Proteins.

Book excerpt: This volume is devoted entirely to inorganic and organometallic stereochemical subjects. Discusses the systematic notations that have been developed to satisfy the needs for a rational and systematic stereochemical nomenclature. Reviews the stereochemical aspects of the changes of bonding at carbon centers induced by metals, either catalytically or stoiciometrically. Also reviews the major achievements in current stereochemical research—the synthesis of asymmetric compounds mediated by transition metals. Discusses the structures of transition metal carbonyl clusters, summarizing recent progress in this expanding area and providing a semiquantitative rationalization of the structures for these clusters.
