Book Description
The Porphyrins, Volume I: Structure and Synthesis, Part Ais the first in a series of seven volumes and covers topics like nomenclature, purification, and structural determination of porphyrins, metalloporphyrins, and other related compounds. This volume serves to be a critical review of the topics covered and presents a complete and comprehensible discussion on the chemistry and biochemistry of porphyrins. The chapters in the text tackle the history and geochemistry of porphyrins and related systems. Also covered and discussed in the chapters is the synthesis of porphyrins from mono-, di-, and tetrapyrrolic intermediates. The isolation and modification of porphyrins from natural sources are also discussed. Other related compounds are also included, such as metallo-, aza-, and N-methylporphyrins, and their synthesis and properties. This book is a good introduction and reference for students studying in the fields of chemistry and biochemistry.

Book Description
The Porphyrins, Volume III: Physical Chemistry, Part A deals with the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related systems. The book covers electronic structure and spectroscopy including circular dichroism and magnetic circular dichroism as well as electronic, infrared, resonance Raman, and Zeeman spectroscopy. Porphyrin stereochemistry, X-ray crystallography, and mass spectroscopy are also included. This volume is organized into 12 chapters and begins with an overview of the optical absorption and emission spectra of porphyrins and the theory by which these facts are understood. The discussion then shifts to the electronic states of the iron porphyrin complex in various heme proteins as displayed by the light absorption properties in the visible region of the electromagnetic spectrum. The reader is methodically introduced to the electronic absorption spectra and molecular orbital theory of chlorophylls, the magnetic optical activity of porphyrins and hemoproteins, and circular dichroism studies of hemoproteins. The book also examines the mass spectra and infrared spectroscopy of porphyrins, resonance Raman scattering from metalloporphyrins and hemoproteins, and photographic essay of porphyrins and related macrocycles. It then concludes with a chapter on high-resolution Zeeman spectroscopy of metalloporphyrins. This book should be useful to inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.

Book Description
Oxidative catalysis by metalloporphyrin systems occupies a prominent role in the current research in the fields of chemical and biological catalysis. Our particular interest and approach has been to collect in the same volume papers dealing with both the chemical and biological aspects of the reactivity of heme systems because of the realization that a better understanding of the complementary discipline can be extremely useful for the researchers from either field. The current progress of the research on synthetic metalloporphyrin catalysts has led to the development of several systems that are able to reproduce the heme-enzyme mediated oxygenation and oxidation reactions, at least in terms of reaction types, mechanisms and often rates. These achievements have stimulated the of creating metalloporphyrin catalysts which are both ambitious project efficient and stable enough to become competitive for large-scale industrial processes. Although this project is still far from being realized, the efforts in this direction parallel those aimed at the application of heme enzymes to chemical technologies, e. g. for the mild, selective oxidation of organics or the detoxification of pollutants. Both the two approaches will be advantageous because while the enzyme systems can achieve selectivities which are probably unattainable by synthetic catalysts, the latter can be active under experimental conditions that would readily inactivate the enzymes.

Book Description
This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine. Each chapter deals with a particular iodine compound or families of compounds which have been used as reagents in a plethora of useful transformations. These include assorted oxidation, such as with the precious Dess-Martin reagent as well as with a wide range of further reactions. Prominent features of hypervalent iodine reagents derived from iodobenzene are: ready availability, operational simplicity, mild reaction conditions, and high efficiency. They are environmentally safe and can be recycled. New species may be easily prepared by introducing substituents in the benzene ring or changing the ligand attached to iodine. Their combination with other reagents broadens considerably their synthetic potential. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine reagents. - Features up-to-date coverage of a wide range of topics - Includes many tables featuring a diversity of reactivity, and a comprehensive index - Acts as a comprehensive, up-to-date reference on all aspects of hypervalent iodine chemistry - Contains a section on unusual efficiency of hypervalent iodine reactions

Book Description
As editor of the two-part Volume V on photosynthesis in RUHLAND'S Encyclopedia, the forerunner of this series published in 1960, I have been approached by the editors of the present volume to provide a short preface. The justification for following this suggestion lies in the great changes which have been taking place in biology in the two decades between these publications, changes which are reflected in the new editorial plan. Twenty years ago it appeared convenient and formally easy to consider photo synthesis as a clearly separated field of research, which could be dealt with under two major headings: one presenting primarily photochemical and biochemical prin ciples, the other physiological and environmental studies. Such a partition, however, as far as aims and opinions of the authors were concerned, resulted in a rather heterogeneous volume. Today, the tendency in experimental biology is towards a merger of previously distinct disciplines. Biochemists and biophysicists have developed their methods to such an extent that, over and above the analysis of individual reaction sequences, work on the manifold interrelationships among cellular activities has become in creasingly possible. Joining them in growing numbers are the physiologists and ecologists with their wealth of information on activity changes in vivo and on the variability and efficiency of the organisms concerned. Furthermore, biochemists, biophysicists and physiologists also now share a lively interest in ultrastructure research, the results and implications of which, through continually improving methodology, have generated important stimuli for the work in the field of cell function.

Book Description
The Porphyrins, Volume II: Structure and Synthesis, Part B is devoted to the structure and synthesis of porphyrins, their precursors, catabolic derivatives, and related systems. The book also covers nomenclature, history, geochemistry, purification, and structural determination of porphyrins, metalloporphyrins, and mono- and polypyrrolic compounds. This volume is organized into 10 chapters and begins with an overview of hydroporphyrins, paying particular attention to their synthesis and stereochemistry as well as reactivity, spectroscopy, and analogues. This book then discusses the synthesis, properties, thermodynamic stability, and evolution of porphyrinogens. The following chapters focus on porphyrins reversibly modified at the periphery by oxidation (oxophlorins) and by irreversible reactions at the periphery. The synthesis of photoexcited porphyrins, metalloporphyrins, and chlorophylls is covered. In addition, chapters on linear polypyrroles, their metal complexes, and macrocycles other than porphyrins are included. This book should be useful to inorganic, organic, physical, and biochemists interested in porphyrin chemistry and biochemistry.
