The correlation of spectroscopic and chemical investigations in recent years has been highly beneficial of many reasons. Around 1950, no valid explanation was available of the colours of compounds of the five tran sition groups. Later, it was possible to identify the excited levels with those expected for an electron configuration with adefinite number of electrons in the partly filled shell. I t is not generally recognized that this is equivalent to determining spectroscopic oxidation states related to the preponderant electron configuration and not to estimates of the fractional atomic charges. This brings in an entirely different type of description than the formal oxidation numbers used for characterizing compounds and reaction schemes. However, it must be realized that collectively oxidized ligands, formation of cluster-complexes and catenation may prevent the oxidation state from being well-defined. The writer would like to express his gratitude to many, but first of all to DR. CLAUS SCHÄFFER, University of Copenhagen, who is the most efficient group-theoretical engineer known to the writer; his comments and discussions have been highly valuable. The writer's colleague, Pro fessor FAUSTO CALDERAZZO (now going to the University of Pisa) has been most helpful in metallo-organic questions. Thanks are also due to Professors E. RANcKE-MADsEN and K. A. JENSEN for correspondence and conversations about formal oxidation numbers.
A practical guidebook illustrating the applications of spectroelectrochemistry to the understanding of redox reactions through identification of their intermediaries and products.
This book covers the general properties of heterocyclic compounds and methods for their preparation to use in applications of green chemistry. Heterocyclic compounds are an important class of molecules in organic chemistry due to their presence in natural products and their use in pharmaceuticals and new materials. They also play a vital role in the metabolism of living cells. Heterocyclic compounds have a wide range of applications in agrochemicals, pharmaceuticals, veterinary products, etc. This research-oriented volume is ideal for readers who want to fully realize the almost limitless potential of heterocyclic compounds and to discover new and effective pharmaceuticals among heterocyclic compounds, the largest and most varied family of organic compounds. The book features several case studies and step-by-step descriptions of synthetic methods and practical techniques. It also serves as a guide for chemists, offering them new insights and new paths to explore for effective drug discovery.
Metal ions play an important role in analytical chemistry, organometallic chemistry, bioinorganic chemistry, and materials chemistry. This book, Descriptive Inorganic Chemistry Researches of Metal Compounds, collects research articles, review articles, and tutorial description about metal compounds. To perspective contemporary researches of inorganic chemistry widely, the kinds of metal elements (typical and transition metals including rare earth; p, d, f-blocks) and compounds (molecular coordination compounds, ionic solid materials, or natural metalloenzyme) or simple substance (bulk, clusters, or alloys) to be focused are not limited. In this way, review chapters of current researches are collected in this book.
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Schiff bases, originally introduced by German chemist Hugo Schiff in 1864, are well-known imine or azomethine (RR’C=NR”) moieties prepared from aldehydes and primary amines through condensation. Since then, Schiff bases have been recognized not only as compounds but also as useful ligands for metal complexes in inorganic coordination chemistry. This is because Schiff bases are essentially Lewis bases having lone pairs on the nitrogen (N) atom (M:N=CHR). In both organic and coordination chemistry, as well as related fields of science, the functions of Schiff base complexes and materials are of great interest. This book introduces and discusses novel aspects of Schiff base compounds.
