Available in PDF, EPUB and Kindle. Book excerpt: Frustrated Lewis Pairs (FLPs) describe combinations of sterically encumbered Lewis acids and bases that do not form classical adducts. This unquenched reactivity has been shown to activate a wide plethora of small molecules, including H2, CO2, alkynes and ketones. While many different main group compounds have been applied in this context, studies of group 16 elements in FLP chemistry remain scarce. The main objective of this dissertation is to expand the scope of FLP chemistry to include group 16 elements, as they can function both as Lewis bases and as Lewis acids. The first portion of this dissertation focuses on the syntheses and reactivity studies of tellurium-boron heterocycles, wherein tellurium acts as a Lewis base. 1,1-carboboration of tellurium-substituted acetylides was shown to proceed smoothly at room temperature, leading to the formation of Te/B intramolecular FLP and 1,4-telluraborine. Several 1,4-telluraborines were found to have mild to high aromaticity as manifested by their unusual stability against oxygen and moisture. They can also undergo a number of unique reactions, including FLP-type alkyne exchange reactions and selective protonolysis of the exocyclic B-C bond. These findings allowed for the facile derivatization of this new class of compounds. Next, we explored the use of hypervalent sulfur and tellurium compounds as Lewis acids. Fluorosulfoxonium cations were successfully synthesized and shown to be Lewis acidic by both computational and experimental methods. On the other hand, although the syntheses of tellurium(IV)-based Lewis acids were achieved, their instability and fluxional solution state behaviour prevented detailed studies on their utility as Lewis acid catalysts. Lastly, in chapter 5, we re-visited the known 1,1-carboboration reaction of terminal alkynes by B(C6F5)3 and report a new method of E/Z isomerization using bulky Lewis bases. The mechanism of isomerization was shown computationally to proceed via a zwitterionic borataalkene intermediate.

Download or read book Organic Mechanisms written by Reinhard Bruckner and published by Springer Science & Business Media. This book was released on 2010-01-20 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions · Stereochemistry · Modern Synthetic Methods is aimed at those who desire to learn organic chemistry through an approach that is facile to understand and easily committed to memory. Michael Harmata, Norman Rabjohn Distinguished Professor of Organic Chemistry (University of Missouri) surveyed the accuracy of the translation, made certain contributions, and above all adapted its rationalizations to those prevalent in the organic chemistry community in the English-speaking world. Throughout the book fundamental and advanced reaction mechanisms are presented with meticulous precision. The systematic use of red "electron-pushing arrows" allows students to follow each transformation elementary step by elementary step. Mechanisms are not only presented in the traditional contexts of rate laws and substituent effects but, whenever possible, are illustrated using practical, useful and state-of-the-art reactions. The abundance of stereoselective reactions included in the treatise makes the reader familiar with key concepts of stereochemistry. The fundamental topics of the book address the needs of upper-level undergraduate students, while its advanced sections are intended for graduate-level audiences. Accordingly, this book is an essential learning tool for students and a unique addition to the reference desk of practicing organic chemists, who as life-long learners desire to keep abreast of both fundamental and applied aspects of our science. In addition, it will well serve ambitious students in chemistry-related fields such as biochemistry, medicinal chemistry and pharmaceutical chemistry. From the reviews: "Professor Bruckner has further refined his already masterful synthetic organic chemistry classic; the additions are seamless and the text retains the magnificent clarity, rigour and precision which were the hallmark of previous editions. The strength of the book stems from Professor Bruckner’s ability to provide lucid explanations based on a deep understanding of physical organic chemistry and to limit discussion to very carefully selected reaction classes illuminated by exquisitely pertinent examples, often from the recent literature. The panoply of organic synthesis is analysed and dissected according to fundamental structural, orbital, kinetic and thermodynamic principles with an effortless coherence that yields great insight and never over-simplifies. The perfect source text for advanced Undergraduate and Masters/PhD students who want to understand, in depth, the art of synthesis ." Alan C. Spivey, Imperial College London "Bruckner’s ‘Organic Mechanisms’ accurately reflects the way practicing organic chemists think and speak about organic reactions. The figures are beautifully drawn and show the way organic chemists graphically depict reactions. It uses a combination of basic valence bond pictures with more sophisticated molecular orbital treatments. It handles mechanisms both from the "electron pushing perspective" and from a kinetic and energetic view. The book will be very useful to new US graduate students and will help bring them to the level of sophistication needed to be serious researchers in organic chemistry." Charles P. Casey, University of Wisconsin-Madison "This is an excellent advanced organic chemistry textbook that provides a key resource for students and teachers alike." Mark Rizzacasa, University of Melbourne, Australia.

Download or read book Arrow Pushing in Inorganic Chemistry written by Abhik Ghosh and published by John Wiley & Sons. This book was released on 2014-07-25 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Involved as it is with 95% of the periodic table, inorganic chemistry is one of the foundational subjects of scientific study. Inorganic catalysts are used in crucial industrial processes and the field, to a significant extent, also forms the basis of nanotechnology. Unfortunately, the subject is not a popular one for undergraduates. This book aims to take a step to change this state of affairs by presenting a mechanistic, logical introduction to the subject. Organic teaching places heavy emphasis on reaction mechanisms - "arrow-pushing" - and the authors of this book have found that a mechanistic approach works just as well for elementary inorganic chemistry. As opposed to listening to formal lectures or learning the material by heart, by teaching students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing, this book serves as a gentle and stimulating introduction to inorganic chemistry, providing students with the knowledge and opportunity to solve inorganic reaction mechanisms. • The first book to apply the arrow-pushing method to inorganic chemistry teaching • With the reaction mechanisms approach ("arrow-pushing"), students will no longer have to rely on memorization as a device for learning this subject, but will instead have a logical foundation for this area of study • Teaches students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing • Provides a degree of integration with what students learn in organic chemistry, facilitating learning of this subject • Serves as an invaluable companion to any introductory inorganic chemistry textbook

This book was released on 2021-11-17 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for senior undergraduate and graduate students, as well as those chemists unfamiliar with "frustrated Lewis pairs (FLPs)", this text serves as an introduction to the both the concept and application of FLPs in hydrogenation catalysis. The book begins by setting the stage as it was around the turn of the century. While the dramatic impacts of catalysis were undeniable, there was dependence of such technologies on transition metal chemistry. Contrastingly, the chemistry of main group elements was dominated by Lewis acid-base behavior. However, these perceptions were altered with the discovery of the ability of "frustrated Lewis pairs (FLPs)" to activate dihydrogen. The basic features, and mechanisms of action of these unique main group systems are chronicled, while the evolution of the initial findings to applications in catalytic hydrogenation is discussed. A subsequent chapter focuses on the breadth of organic substrates for which borane based FLP hydrogenations are effective. This is furthered with a chapter on the metal-free enantioselective reductions. FLP chemistry is not limited to systems involving boranes and this book also catalogues a range of FLP hydrogenation catalysts involving elements from across the periodic table. The final chapter in the book describes other directions of interest where the application of the concept of FLPs hydrogenation are beginning to emerge. Ideal for course use and self study, this book provides synthetic chemists with a fresh, expert introduction to the field. The reader will be left recognizing that hydrogenation catalysts is a domain no longer limited to transition metals.
