A hands-on guide to assist in the planning and execution of synthetic reactions in the laboratory Despite the maturity of organic chemistry, it can still be very challenging to identify optimal methods for synthetic transformations that perform as well in real-world manufacturing processes as they do in the laboratory. This detailed and accessible guide attempts to address this vexing issue and deliver proven methodologies practicing synthetic chemists will find valuable for identifying reaction conditions that work reliably over the broadest possible range of substrates. Practical Synthetic Organic Chemistry: Provides a practical guide to strategically planning and executing chemical syntheses for the bench chemist in industry Discusses information that is not common knowledge beyond the boundaries of process chemistry groups, such as the synthetic routes of selected contemporary pharmaceutical drugs and practical solvents, as well as green chemistry concepts Highlights key reactions, including substitutions, additions, eliminations, rearrangements, oxidations, and reductions Addresses basic principles, mechanisms, advantages and disadvantages of the methodology, and techniques for achieving laboratory success Incorporating such an extraordinary wealth of information on organic chemistry and its related fields into one complete volume distinguishes Practical Synthetic Organic Chemistry as an incomparable desktop reference for professionals—and an invaluable study aid for students.

'Where shall we position these masterpieces of the chemical demonstrator's art? Somewhere between white magic and science. Somewhere between gripping theater and chemistry. Somewhere between circus and the Zen koan... The remarkable achievement of Herbert Roesky's and Klaus Mockel's book is the linkage it achieves between the world of the human spirit, expressed in literature and historical continuity, and the art of chemical demonstration. One expects Goethe to move freely in the pages of 'Chemische Kabinettstucke', but Whitman, Nietzsche, Thomas Mann, Salvador Dali, Montaigne, and the prophet Jeremiah! They serve too, authentically and ingeniously, in the authors' deeply humanistic approach to science. The chemical and literary strands of this book are so ably intertwined.'

Consolidating knowledge from a number of disciplines, Ion-Radical Organic Chemistry: Principles and Applications, Second Edition presents the recent changes that have occurred in the field since the publication of the first edition in 2003. This volume examines the formation, transformation, and application of ion-radicals in typical conditions of organic synthesis. Avoiding complex mathematics, the author explains the principles of ion-radical organic chemistry and presents an overview of organic ion-radical reactions. He reviews methods of determining ion-radical mechanisms and controlling ion-radical reactions. Wherever applicable, the text addresses issues relating to ecology and biomedical concerns as well as inorganic participants of the ion-radical organic reactions. After reviewing the nature of organic ion-radicals and their ground-state electronic structure, the book discusses their formation, the relationship between electronic structure and reactivity, mechanism and regulation of reactions, stereochemical aspects, synthetic opportunities, and practical applications. Additional topics include electronic and opto-electronic devices, organic magnets and conductors, lubricants, other materials, and reactions of industrial or biomedical importance. The book concludes by providing an outlook on possible future development in this field. Researchers and practitioners engaged in active work on synthetic or mechanistic organic chemistry and its practical applications will find this text to be invaluable in both its scope and its depth.

Studenten aller Fachrichtungen der Chemie und Pharmazie lernen heute Strukturaufklärung durch kernmagnetische Resonanz (NMR). Es gibt kaum eine Diplom-, Examens- oder Doktorarbeit, in der nicht ein Problem mit Hilfe von NMR gelöst wird. Gefragt sind daher preiswerte Texte, die dem Studenten an Beispielen zeigen, wie man NMR bei der Strukturaufklärung einsetzt. Etab lierte Werke der NMR-Spektroskopie behandeln physikalische Grundlagen alter und neuer Methoden sowie die Zusammenhänge zwischen NMR-Parametern und chemischer Struktur. Sie vermitteln kaum das "gewußt wie" der Strukturauf klärung mit NMR, geben also wenig konkrete taktische und strategische Hinweise auf den gedanklichen Weg "vom NMR-Spektrum zur Strukturformel". Dieser aus zahlreichen Vorlesungen und Seminaren herangereifte Text ist ein Versuch, dem Studenten, Diplomanden und Doktoranden einen systematischen, gut lesbaren und preiswerten Einstieg in die Taktik der Strukturaufklärung durch NMR zu vermitteln. Er stimmt den Leser mit einem absichtlich sehr kurzen Repetitorium der elementaren Grundbegriffe, Meßgrößen und Meßver fahren ein. Etablierte Lehrbücher sollen ja nicht ersetzt werden. Es folgt eine Einführung in die Taktik der Strukturaufklärung mit ein- und zweidi mensionalen NMR-Methoden. Im Vordergrund steht dabei stets die Frage, wie Messungen und daraus resultierende Parameter in Teilstrukturen übersetzt werden. Das Kapitel orientiert nicht, wie sonst üblich, über physikalische Grundlagen der Meßmethoden, Theorie der chemischen Verschiebung und Spin Spin-Kopplung. Vielmehr gliedert es sich in die wesentlichen Teilaspekte der Molekülstruktur , welche bei der Identifizierung jeder Verbindung zu klären sind: Konstitution, relative Konfiguration und Konformation, abso lute Konfiguration, intra- und intermolekulare Wechselwirkungen, Molekül dynamik.

Organic Photochemistry outlines the principles, techniques and well-known reactions occurring in organic molecules and also illustrates more complex photochemical transformations occurring in organic chemistry. Many photochemical transformations convert simple molecules into extremely complex products with an ease not approached by the standard synthetic chemistry practiced in the laboratory. In the earlier chapters, the author outlines the principles, techniques and some of the well-known reactions occurring in organic molecules and later illustrates more complex photochemical transformations occuring in organic chemistry. Experimental techniques are included to encourage novices. Topics are emphasized where structural transformations can be formulated chemically. Practical applications are collected together. The book starts at a comfortably simple level with enough examples to provide an introduction to the diversity of photochemical reactions. * Includes experimental techniques to encourage novices. * Emphasizes topics where structural transformations can be formulated chemically * Collects and presents practical applications * Written in a simple style including enough examples to serve as an introduction to the diversity of photochemical reactions

The book opens with a general overview of the constitution and reactivity of organomagnesium compounds, followed by information on handling them and on their detection and estimation. Throughout, practical aspects aswell as principles are emphasized. The chapters on the synthesis of organomagnesium compounds cover the preparation of special forms of metallic magnesium and the reaction of magnesium with substrates such as dienes, as well as the traditional preparation of Grignard reagents. Preparations by metallation and metal-halogen exchanges are also included, as are newer methods such as hydromagnesiation of alkenes and alkynes. Systematic coverage is provided on synthetically useful reactions of organomagnesium compounds. Of fundamental importance in organic synthesis are carbon-carbon bond forming reactions; additions to carbon-carbon, carbon-nitrogen, carbon-oxygen, and carbon-sulfur multiple bonds; and nucleophilic substitution at carbon. The formation of carbon-heteroatom bonds in organic compounds is described, where the heteroatom is hydrogen, nitrogen, oxygen, sulfur, or halogen. Finally, the use of organomagnesium compounds in preparing other organometalloid and organometallic compounds is outlined. Representative experimental procedures are included throughout the book, and tables with references to well-described examples are provided.

Bewährte Qualität in 2. Auflage: Sie richtet sich an Studenten, Lehrende und praktizierende Wissenschaftler der (Bio)chemie, Pharmazie, Medizin und Biologie, die sich mit dem Phänomen der Chiralität befassen. Neben einer genauen Formeldarstellung ist eine klare und eindeutige Terminologie zur Beschreibung der dreidimensionalen Strukturen und der daraus resultierenden Konsequenzen für Reaktionen oder Wirkstoff-Rezeptor-Wechselwirkungen unerlässlich. Das gilt umso mehr für den zunehmenden interdisziplinären Austausch. Der Autor erklärt hier alle wichtigen Begriffe in lexikalischer Form und weist auf deren richtige Verwendung hin.
