Available in PDF, EPUB and Kindle. Book excerpt: The work herein describes the investigation of highly reactive organic molecules. By synthesizing, isolating, and spectroscopically characterizing molecules of this type, driving forces underlying many chemical processes can be exploited. In Chapter 1, I describe the investigation of the alkylated carbon chain Me-C3-Me. The structure and photochemistry of this surprisingly complex substituted propargylene requires the combination of nontrivial synthesis, elaborate computational analysis, and IR, UV-vis, and EPR spectroscopies to fully understand. The second chapter details my contributions to a project originating from a matrix-isolation study in the lab of Rui Fausto and facilitated on site at Wisconsin by Dr. Cláudio Nunes. Our work together involved probing a hydrogen-migration reaction of an aldehyde hydrogen to a nitrene that is believed to occur through a tunneling process. Much like the matrix-isolation study in Chapter 1, this project involves synthesis of precursors to the nitrene species, matrix isolation, and IR, UV/vis, and EPR spectroscopies. The third chapter shifts gears from low-temperature studies of reactive intermediates to the kinetic study of thermally activated Bergman cyclization reactions using in situ IR spectroscopy. Chapter 4 describes a body of work in collaboration with the Zwier research group at Purdue University. In line with our focus on astrochemistry, the Zwier group is interested in sophisticated spectroscopic investigations of the photochemistry and discharge-driven chemistry of chemical systems relevant to the atmosphere of Saturn's largest moon, Titan. Their interest in expanding their spectroscopic search to nitrile functionality (particularly relevant to chemistry on Titan) necessitated the synthesis of a small family of unsaturated nitriles. Chapter 5 introduces my experiences in discipline based education research that I have pursued through my internship with the Delta program. In this project, I implemented a flipped classroom in a general chemistry class at Madison College and assessed the cognitive skills engaged by the students. I have found consistency between my research and educational interests by remaining grounded in crosscutting concepts and emphasizing them in the presentation of my research and in the classroom. By maintaining this focus, a firm foundation can be built from which knowledge can be constructed and discovery can flourish.

Available in PDF, EPUB and Kindle. Book excerpt: Examines the latest applications of photochemistry to generate important intermediates Presenting the latest breakthroughs in the field of organic photochemistry, this book offers tested and proven photochemical approaches to synthesis, creating promising new possibilities and applications for photochemical reactions. It focuses on photoreactions involving an intermediate where mechanistic aspects control the course of the reaction and its synthetic value. Readers will discover new insights into the mechanisms and nature of photo-produced reactive intermediates for organic synthesis as well as the methods to generate them. Moreover, by focusing on highly efficient techniques for producing such species, the authors enable researchers to design and perform photoreactions within the framework of green, sustainable chemistry. Photochemically-Generated Intermediates in Synthesis begins with a discussion of the principles and practice of photo-generated intermediates. Next, the book explores: Photogeneration of carbon-centered radicals Photogeneration of heteroatom-centered radicals Photogeneration of biradicals and radical pairs Photochemical generation of radical ions Photogeneration of carbocations and carbanions Photogeneration of carbenes and nitrenes The book's final chapter is dedicated to the photochemical manipulation of intermediates. Each chapter includes key kinetic data for typical intermediates as well as detailed case examples, giving readers all the tools needed to perform their own photochemical reactions. Comparisons to non-photochemical methods are offered whenever possible. Photochemically-Generated Intermediates in Synthesis sets the stage for greater collaboration among photochemists and synthetic organic chemists, enabling these two research communities to fully leverage photochemistry in order to generate key intermediates needed for a broad range of synthetic reactions in organic chemistry.

Download or read book Synthetic Organic Photochemistry written by W.M. Horspool and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all major branches of organic chemistry, I think none has undergone such a rapid, even explosive, development during the past twenty-five years as organic photochemistry. Prior to about 1960, photochemistry was still widely regarded as a branch of physical chemistry which might perhaps have oc casional applications in the generation of free radicals. Strangely enough, this attitude to the subject had developed despite such early signs of promise as the photodimerization of anthracene first observed by Fritzsche in 1866, and some strikingly original pioneering work by Ciamician and Silber in the early years of this century. These latter workers first reported such varied photo reactions as the photoisomerization of carvenone to carvone camphor, the photodimerization of stilbene, and the photoisomerization of o-nitrobenzal dehyde to o-nitrosobenzoic acid; yet organic chemists continued for another fifty years or so to rely almost wholly on thermal rather than photochemical methods of activation in organic synthesis-truly a dark age. When my colleagues and I first began in the 1950s to study the synthetic possibilities of photoexcitation in the chemistry of benzene and its derivatives, virtually all the prior reports had indicated that benzene was stable to ultraviolet radiation. Yet I think it fair to say that more different types of photoreactions than thermal reactions of the benzene ring are now known. Comparable growth of knowledge has occurred in other branches of organic photochemistry, and photochemical techniques have in particular made possible or simplified the synthesis of numerous highly strained organic molecules.

Download or read book Introduction to Organic Photochemistry written by J. D. Coyle and published by John Wiley & Sons. This book was released on 1991-01-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Organic Photochemistry John D. Coyle, The Open University, Milton Keynes The purpose of this book is to provide an introductory account of the major types of organic photochemical reactions, to enable those with a prior knowledge of basic organic chemistry to appreciate the differences between processes which occur photochemically (through an electronically excited state) and those that occur thermally (directly from the electronic ground state). The material is organized according to organic functional groups, in parallel with the approach adopted in most general textbooks on organic chemistry. In this respect it differs from many of the existing, older organic photochemistry texts. The first chapter provides an account of the distinctive features of photochemical reactions, and a physical/mechanistic framework for the descriptions in the rest of the book. The overall emphasis is on organic photoreactions potentially useful in synthesis. The book thus integrates this branch of chemistry with broader aspects of the subject, and introduces the reader to important applications of organic photochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
