Electron Flow in Organic Chemistry


Book Description

Sets forth the analytical tools needed to solve key problems in organic chemistry With its acclaimed decision-based approach, Electron Flow in Organic Chemistry enables readers to develop the essential critical thinking skills needed to analyze and solve problems in organic chemistry, from the simple to complex. The author breaks down common mechanistic organic processes into their basic units to explain the core electron flow pathways that underlie these processes. Moreover, the text stresses the use of analytical tools such as flow charts, correlation matrices, and energy surfaces to enable readers new to organic chemistry to grasp the fundamentals at a much deeper level. This Second Edition of Electron Flow in Organic Chemistry has been thoroughly revised, reorganized, and streamlined in response to feedback from both students and instructors. Readers will find more flowcharts, correlation matrices, and algorithms that illustrate key decision-making processes step by step. There are new examples from the field of biochemistry, making the text more relevant to a broader range of readers in chemistry, biology, and medicine. This edition also offers three new chapters: Proton transfer and the principles of stability Important reaction archetypes Qualitative molecular orbital theory and pericyclic reactions The text's appendix features a variety of helpful tools, including a general bibliography, quick-reference charts and tables, pathway summaries, and a major decisions guide. With its emphasis on logical processes rather than memorization to solve mechanistic problems, this text gives readers a solid foundation to approach and solve any problem in organic chemistry.




Strained Organic Molecules


Book Description

Strained Organic Molecule, Volume 38 considers the vast field of strained organic molecules. The book discusses energy and entropy; cyclopropane and cyclobutane; and unique strained groupings or building blocks. The text also describes the aesthetics, rearrangements, and topology of polycycles; kinetic and thermodynamic stability; and tetrahedral tetracoordinate carbon. The inverted tetrahedra, propellanes, buttaflanes, and paddlanes; planar methane and its derivatives; and five- and six-coordinaste carbon are also considered. Chemists will find the book invaluable.




Chemistry3


Book Description

Chemistry3 establishes the fundamental principles of all three strands of chemistry; organic, inorganic and physical. By building on what students have learned at school, using carefully-worded explanations, annotated diagrams and worked examples, it presents an approachable introduction to chemistry and its relevance to everyday life.




Comprehensive Organic Synthesis: Additions to and substitutions at C-C[pi]-Bonds


Book Description

Volume 4 focuses on additions and the resulting substitutions at carbon-carbon &pgr;-bonds. Part 1 includes processes generally considered as simple polar reactions, reactive electrophiles and nucleophiles adding to alkenes and alkynes. A major topic is Michael-type addition to electron deficient &pgr;-bonds, featured in the first six chapters. In part 2 are collected the four general processes leading to nucleophilic aromatic substitution, including radical chain processes and transition metal activation through to &pgr;-complexation. Metal-activated addition (generally by nucleophiles) to alkenes and polyenes is presented in part 3, including allylic alkylation catalyzed by palladium. The coverage of nonpolar additions in part 4 includes radical additions, organometal addition (Heck reaction), carbene addition, and 1,3-dipolar cycloadditions.




The Art of Writing Reasonable Organic Reaction Mechanisms


Book Description

Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.




Hypercarbon Chemistry


Book Description

The essential new edition of the book that put hypercarbon chemistry on the map A comprehensive and contemporary treatment of the chemistry of hydrocarbons (alkanes, alkenes, alkynes, and aromatics) towards electrophiles, Hypercarbon Chemistry, Second Edition deals with all major aspects of such chemistry involved in hydrocarbon transformations, and of the structural and reaction chemistry of carboranes, mixed hydrides in which both carbon and boron atoms participate in the polyhedral molecular frameworks. Despite the firmly established tetravalency, carbon can bond simultaneously to five or more other atoms. "Hypercarbon" bonding permeates much organic, inorganic and organometallic chemistry, and the book serves as the compendium for this phenomenon. Copious diagrams illustrate the rich variety of hypercarbon structures now known, and patterns therein. Individual chapters deal with specific categories of compound (e.g. organometallics, carboranes, carbocations) or transformations that proceed through transient hypercarbon species, detailing fundamental chemistry, including reactivity, selectivity, stereochemistry, mechanistic factors and more.




The Group 13 Metals Aluminium, Gallium, Indium and Thallium


Book Description

The last two decades have seen a renaissance in interest in the chemistry of the main group elements. In particular research on the metals of group 13 (aluminium, gallium, indium and thallium) has led to the synthesis and isolation of some very novel and unusual molecules, with implications for organometallic synthesis, new materials development, and with biological, medical and, environmental relevance. The Group 13 Metals Aluminium, Gallium, Indium and Thallium aims to cover new facts, developments and applications in the context of more general patterns of physical and chemical behaviour. Particular attention is paid to the main growth areas, including the chemistry of lower formal oxidation states, cluster chemistry, the investigation of solid oxides and hydroxides, advances in the formation of III-V and related compounds, the biological significance of Group 13 metal complexes, and the growing importance of the metals and their compounds in the mediation of organic reactions. Chapters cover: general features of the group 13 elements group 13 metals in the +3 oxidation state: simple inorganic compounds formal oxidation state +3: organometallic chemistry formal oxidation state +2: metal-metal bonded vs. mononuclear derivatives group 13 metals in the +1 oxidation state mixed or intermediate valence group 13 metal compounds aluminium and gallium clusters: metalloid clusters and their relation to the bulk phases, to naked clusters, and to nanoscaled materials simple and mixed metal oxides and hydroxides: solids with extended structures of different dimensionalities and porosities coordination and solution chemistry of the metals: biological, medical and, environmental relevance III-V and related semiconductor materials group 13 metal-mediated organic reactions The Group 13 Metals Aluminium, Gallium, Indium and Thallium provides a detailed, wide-ranging, and up-to-date review of the chemistry of this important group of metals.
