Book Description
Activated Metals in Organic Synthesis discusses fundamental principles of the generation of activated, highly reactive metals, and their applications in organic synthesis. Following an introductory chapter on basic forms of metals the chapters in Part 1 are devoted to common strategies utilized for the preparation of active metals. These strategies include vaporization and subsequent co-condensation of metal atoms, in addition to depassivating methods employed commonly in laboratory syntheses. Chapters in Part 2 discuss relevant organic transformations in which metal activation plays a crucial role. Specific topics covered include metal-induced reductive methods; pinacolic, Reformatsky-, and Barbier-type reactions; McMurry ketone-olefin coupling; and the Bernet-Vasella reaction. Each chapter is followed by literature citations ranging from specific references to significant reviews. Many structural formulas are provided, making it easy to follow each synthesis. The book will be an important reference for students, organic chemists, and researchers in all areas of organometallic chemistry.

Book Description
hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known to be the less reactive organic compounds. Saturated hydrocarbons may be called the “noble gases of organic chemistry” and, if so, the first representative of their family – methane – may be compared with extremely inert helium. As in all comparisons, this parallel between noble gases and alkanes is not fully accurate. Indeed the transformations of alkanes, including methane, have been known for a long time. These reactions involve the interaction with molecular oxygen from air (burning – the main source of energy!), as well as some mutual interconversions of saturated and unsaturated hydrocarbons. However, all these transformations occur at elevated temperatures (higher than 300–500 °C) and are usually characterized by a lack of selectivity. The conversion of alkanes into carbon dioxide and water during burning is an extremely valuable process – but not from a chemist viewpoint.

Book Description
In the last few years a large repetoire of methods for the activation of unreactive organic functionalities and for their use in organic synthesis has been developed. In this volume, areas ranging from the activation of C-H bonds to the chemical transformation of dinitrogen are authoritatively discussed by leading experts in the field. To activate means to be able to cleave otherwise inert chemical bonds. The cleavage and formation of chemical bonds is fundamental to organic synthesis; these new activation methodologies make hitherto infeasible reactions extremely easy and create new opportunities for innovative organic transformations, for both industry and academia. This is the first book that provides a thorough and timely coverage of both inorganic and organic synthetic aspects of bond activation, thus giving a broad overview of the field and allowing both inorganic and organic chemists ready access to the methodologies involved.

Book Description
Organometallic Chemistry is the study of chemical compounds containing bonds between carbon and metal. The term "e;Metal"e; is defined deliberately broadly in this context and may include elements, such as silicon or boron, which are not metallic but are considered to be metalloids. Almost all branches of chemistry and material science now interface with organometallic chemistry. Organometallics find practical uses in stoichiometric and catalytic processes, especially processes involving carbon monoxide and alkene-derived polymers. Organometallic (OM) chemistry is the study of compounds containing, and reactions involving, metal-carbon bonds. The metal-carbon bond may be transient or temporary, but if one exists during a reaction or in a compound of interest, we're squarely in the domain of organometallic chemistry. Despite the denotational importance of the M-C bond, bonds between metals and the other common elements of organic chemistry also appear in OM chemistry: metal-nitrogen, metal-oxygen, metal-halogen, and even metal-hydrogen bonds all play a role. Metals cover a vast swath of the periodic table and include the alkali metals (group 1), alkali earth metals (group 2), transition metals (groups 3-12), the main group metals (groups 13-15, "e;under the stairs"e;), and the lanthanides and actinides. The principal idea of this book is to offer a comprehensive coverage of unconventional and thought-provoking topics in organometallic chemistry. It also supplies practical information about reaction mechanisms, along with the descriptions of contemporary applications to organic synthesis, organized by mechanism and kinetic. It will serve as a valuable reference tool for students and professional of organic and post organic chemistry, who need to become better acquainted with the subject.

Book Description
The activation of dioxygen by metal ions has both synthetic potential and biological relevance. Dioxygen is the cleanest oxidant for use in emission-free technologies to minimize pollution of the environment. The book gives a survey of those catalyst systems based on metal complexes which have been discovered and studied in the last decade. They activate molecular oxygen and effect the oxidation of various organic compounds under mild conditions. Much of the recent progress is due to a search for biomimetic catalysts that would duplicate the action of metalloenzymes. Mechanistic aspects are emphasized throughout the book. An introductonary chapter reviews the chemistry of transition metal dioxygen complexes, which are usually the active intermediates in the catalytic reactions discussed. Separate chapters are devoted to oxidation of saturated, unsaturated and aromatic hydrocarbons, phenols, catechols, oxo-compounds, phosphorus, sulfur and nitrogen compounds.
