Download or read book Hydrocarbon Chemistry written by George A. Olah and published by John Wiley & Sons. This book was released on 2003-09-10 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrocarbons and their transformations play major roles in chemistry as raw materials and sources of energy. Diminishing petroleum supplies, regulatory problems, and environmental concerns constantly challenge chemists to rethink and redesign the industrial applications of hydrocarbons. Written by Nobel Prize-winner George Olah and hydrocarbon expert Árpád Molnár, the completely revised and expanded Second Edition of Hydrocarbon Chemistry provides an unparalleled contemporary assessment of the field, presenting basic concepts, current research, and future applications. Hydrocarbon Chemistry begins by discussing the general aspects of hydrocarbons, the separation of hydrocarbons from natural sources, and the synthesis from C1 precursors with recent developments for possible future applications. Each successive chapter deals with a specific type of hydrocarbon transformation. The Second Edition includes a new section on the chemical reduction of carbon dioxide–focusing on catalytic, ionic, electrocatalytic, photocatalytic, and ezymatic reductions–as well as a new chapter on new catalysts and activation methods, combinatorial chemistry, and environmental chemistry. Other topics covered include: Major processes of the petrochemical industry, such as cracking, reforming, isomerization, and alkylation Derivation reactions to form carbon-heteroatom bonds Hydrocarbon oxidations Metathesis Oligomerization and polymerization of hydrocarbons All chapters have been updated by adding sections on recent developments to review new advances and results. Essential reading for practicing scientists in industry, polymer and catalytic chemists, as well as researchers and graduate students, Hydrocarbon Chemistry, Second Edition remains the benchmark text in its field.

Available in PDF, EPUB and Kindle. Book excerpt: The intramolecular Diels-Alder reaction is widely recognized as a powerful and versatile method for the assembly of complex bicyclic structures in synthetic organic chemistry and has been utilized as a key step in the total syntheses of a number of interesting biologically active natural products. We have studied the use of siloxacyclopentene constrained trienes as a method to control diastereofacial selectivity in the intramolecular Diels-Alder reaction. The siloxacyclopentene constraints could be formed under mild conditions and attached to either the diene or dienophile units of a variety of trienes. These constrained trienes underwent intramolecular Diels-Alder reactions to give cycloadducts with the oxygen contained in the siloxacyclopentene exclusively in an anti-configuration relative to the ring fusion proton. Suitably chosen dienophile activating groups and optimized conditions for cyclization allowed for high levels of selectivity for either cis - or trans -fused cycloadducts in the case of siloxacyclopentenes contained within the diene, while siloxacyclopentenes constraints attached at the dienophile gave exclusively the trans-fused cycloadducts. A siloxacyclopentene constrained tetraene was then utilized in a concise, stereoselective synthesis of the decahydrofluorene core common to the hirsutellones. Synthetic efforts targeting the completion of the hirsutellones via a common biosynthetic intermediate were pursued utilizing a macrobenzannulation strategy. This strategy was abandoned due to inability to prepare a suitable benzannulation precursor. Later a strategy of first forming a five membered ring containing analogue was also pursued, but failed due to an inability to convert a suitable ester to the corresponding furan or thiophene.

Book Synopsis A Deeper Understanding of the Diels-Alder Reaction by : William James Lording
Download or read book A Deeper Understanding of the Diels-Alder Reaction written by William James Lording and published by . This book was released on 2010 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Diels-Alder reaction was discovered in 1928 and has become the most efficient and practical method for the synthesis of six-membered carbocyclic and heterocyclic rings. This thesis comprises three chapters of results and discussion with the Diels-Alder reaction as a theme. Chapter 2 details an investigation of endo:exo selectivity in the Diels-Alder reactions of 1,3-butadiene. Chapter 3 explores aspects of the intramolecular Diels-Alder reactions of some substituted 1,3,8-nonatrienes, and Chapter 4 describes the domino Diels-Alder reactions of 1,4-diiodo-1,3-butadiene. The Diels-Alder reaction is powerful, general, and widely used in chemical synthesis, and it is well known that many Diels-Alder reactions exhibit endo selectivity, in accord with Alder's empirical rule. The origins of endo:exo selectivity in the Diels-Alder reaction, however, are not completely understood and there is a dearth of experimental evidence concerning the Diels-Alder reactions of the archetypal 1,3-diene, 1,3-butadiene. Chapter 2 describes a study of the Diels-Alder reactions of an isotopically labelled 1,3-butadiene with a range of simple dienophiles, allowing the endo:exo selectivities of these important reactions to be determined for the first time. The experimental data shed light on the origins of endo:exo selectivity in the Diels-Alder reaction and will serve as an important reference for future computational investigations in this area. The intramolecular Diels-Alder reaction shares many of the virtues of its intermolecular counterpart, however its use in chemical synthesis is limited because intramolecular Diels-Alder reactivity and stereoselectivity are often governed by subtle factors, and can be very difficult to predict. As part of a comprehensive experimental and computational collaboration, Chapter 3 describes an investigation of the heat and Lewis acid promoted intramolecular Diels-Alder reactions of some ether tethered 1,3,8-nonatrienes. Also presented are the results of a rate study and a kinetic isotope effect study involving the intramolecular Diels-Alder reactions of some 1,3,8-nonatrienes. The experimental data are analysed and compared with predicted stereoselectivities, activation barriers and kinetic isotope effects obtained from computational modelling. Increased efficiency in chemical synthesis conserves resources, reduces waste, and saves time and money. Domino reactions are particularly efficient processes, which can generate complex products from simple reactants. Chapter 4 describes an investigation of the domino Diels-Alder reactions of (1E,3E)-1,4-diiodo-1,3-butadiene with maleimide dienophiles, through which a family of bicyclo[2.2.2]oct-2-ene derivatives are produced in one high yielding and stereoselective synthetic step.

Clark and published by . This book was released on 2008 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the inverse electron demand Diels-Alder reaction of N-sulfonyl-1-aza-1,3-butadienes with electron-rich dienophiles has been extensively examined in our laboratory, we sought to control the absolute configuration of the tetrahydropyridine products and thereby extend the utility of the methodology. The first detailed study of a room temperature asymmetric Diels-Alder reaction of N-sulfonyl-1-aza-1,3-butadienes enlisting a series of nineteen enol ethers bearing chiral auxilaries is described herein. Many of these auxilaries provided highly diastereoselective reactions (in both the endo and facial sense) largely the result of a highly organized [4+2] cycloaddition transition state. Three readily accessible and previously unexplored butyrolactone and pyrrolidinone auxilaries rationally emerged from the studies and provide exceptional selectivities (up to 49:1 endo:exo and 48:1 facial).

Available in PDF, EPUB and Kindle. Book excerpt: "Hexachlorocyclopentadiene and related compounds have been studied extensively in connection with Diels-Alder reactions. Many of the adducts formed are used as intermediates in insecticide syntheses. It is of interest to study the stereochemistry of the adducts of one of the hexachlorocyclopentadiene derivaites. 5,5-Dimethoxy-1,2,3,4-tetrachlorocyclopentadiene and various dienophiles, when allowed to react, yield compounds of the bridges bicyclo [2.2.1] hept-2-ene series. The study of the endo and/or exo configuration of various functional groups such as carboxyl, aldehyde, and hydroxymethyl can be related to the known exo-5-hydroxymethyl1-1,2,3,4-tetrachlorobicyclo-[2.2.1] help-2-ene-7-one"--Introduction, leaf [1].
