In this unit and in the next units, we will srudy some derivatives of hydrocarbons. Replacement of one or more hydrogen atoms in a hycimcarbon by halogen atom(s) [F, CI, Br, or I:] gives the halogen derivatives. These compounds are important laboratory and industrial solvents and serve as intermediates in the synthesis of other organic compounds. Many chlorohydrocarbons have acquired importance as insecticides. Although there are not many naturally occurring halogen derivatives yet you might be familiar with one such compound, thyroxin-a thyroid hormone. In this unit, we shall take up the chemistry of the halogen derivatives in detail beginning with classification of halogen derivatives and then going over to methods of their preparation. We shall also discuss the reactivity'of halogen compounds and focus our attention specially, on some important reactions such as nucleophilic substitution (SN)and elimination (E) reactions. Finally, we shall take up uses of halogen derivatives and the methods for their detection.

  • Chapter 7 - Alkenes and Alkynes I
    Andrew Rosen Chapter 7 - Alkenes and Alkynes I 7.1 - Introduction - The simplest member of the alkenes has the common name of ethylene while the simplest member of the alkyne family has the common name of acetylene 7.2 - The (E)-(Z) System for Designating Alkene Diastereomers - To determine E or Z, look at the two groups attached to one carbon atom of the double bond and decide which has higher priority. Then, repeat this at the other carbon atom. This system is not used for cycloalkenes - If the two groups of higher priority are on the same side of the double bond, the alkene is designated Z. If the two groups of higher priority are on opposite sides of the double bond, the alkene is designated E - Hydrogenation is a syn/cis addition 7.3 - Relative Stabilities of Alkenes - The trans isomer is generally more stable than the cis isomer due to electron repulsions - The addition of hydrogen to an alkene, hydrogenation, is exothermic (heat of hydrogenation) - The greater number of attached alkyl groups, the greater the stability of an alkene 7.5 - Synthesis of Alkenes via Elimination Reactions, 7.6 - Dehydrohalogenation of Alkyl Halides How to Favor E2: - Reaction conditions that favor elimination by E1 should be avoided due to the highly competitive SN 1 mechanism - To favor E2, a secondary or tertiary alkyl halide should be used - If there is only a possibility for a primary alkyl halide, use a bulky base - Use a higher concentration of a strong and nonpolarizable base, like an alkoxide - EtONa=EtOH favors the more substituted double bond

  • Elimination Reactions Are Described
    Introduction In this module, different types of elimination reactions are described. From a practical standpoint, elimination reactions widely used for the generation of double and triple bonds in compounds from a saturated precursor molecule. The presence of a good leaving group is a prerequisite in most elimination reactions. Traditional classification of elimination reactions, in terms of the molecularity of the reaction is employed. How the changes in the nature of the substrate as well as reaction conditions affect the mechanism of elimination are subsequently discussed. The stereochemical requirements for elimination in a given substrate and its consequence in the product stereochemistry is emphasized. ELIMINATION REACTIONS Objective and Outline beta-eliminations E1, E2 and E1cB mechanisms Stereochemical considerations of these reactions Examples of E1, E2 and E1cB reactions Alpha eliminations and generation of carbene I. Basics Elimination reactions involve the loss of fragments or groups from a molecule to generate multiple bonds. A generalized equation is shown below for 1,2-elimination wherein the X and Y from two adjacent carbon atoms are removed, elimination C C C C -XY X Y Three major types of elimination reactions are: α-elimination: two atoms or groups are removed from the same atom. It is also known as 1,1-elimination. H R R C X C + HX R Both H and X are removed from carbon atom here R Carbene β-elimination: loss of atoms or groups on adjacent atoms. It is also H H known as 1,2- elimination. R C C R R HC CH R X H γ-elimination: loss of atoms or groups from the 1st and 3rd positions as shown below.

  • Chapter 7: Haloalkanes
    188 Chapter 7: Haloalkanes Chapter 7: Haloalkanes Problems 7.1 Write the IUPAC name for each compound: CH3 (a) (b) Br Cl 1-chloro-3-methyl-2-butene 1-bromo-1-methylcyclohexane Cl Cl (c) (d) CH3CHCH2Cl 1,2-dichloropropane 2-chloro-1,3-butadiene 7.2 Determine whether the following haloalkanes underwent substitution, elimination, or both substitution and elimination: O (a) KOCCH Br 3 O +KBr CH3COOH O In this reaction, the haloalkane underwent substitution. The bromine group was replaced by an acetate (CH3COO−) group. NaOCH CH (b) 2 3 + +NaCl CH3CH2OH Cl OCH2CH3 In this reaction, the haloalkane underwent both substitution and elimination. In the substitution, the chlorine group was replaced by an ethoxy (CH3CH2O−) group. Chapter 7: Haloalkanes 189 7.3 Complete these nucleophilic substitution reactions: (a) – + + – Br +CH3CH2S Na SCH2CH3 +NaBr O O (b) – + + – Br + CH3CO Na OCCH3 +NaBr 7.4 Answer the following questions: (a) Potassium cyanide, KCN, reacts faster than trimethylamine, (CH3)3N, with 1-chloropentane. What type of substitution mechanism does this haloalkane likely undergo? The rate of this reaction is influenced by the strength of the nucleophile, suggesting that the mechanism of substitution is SN2. The cyanide ion is a much better nucleophile than an amine. (b) Compound A reacts faster with dimethylamine, (CH3)2NH, than compound B.What does this reveal about the relative ability of each haloalkane to undergo SN2? SN1? Br Br A B Compound A is more able to undergo SN2, which involves backside attack by the nucleophile, because it is sterically less hindered than B. Both compounds A and B have about the same reactivity towards SN1, because both A and B can ionize to give carbocations of comparable stability.

  • Double Bond Is Exocyclic. Characterization and Reactions of the Cyclobutenone Were Successfully Carried Out
    AN ABSTRACT OF THE THESIS OF WILLIE EDSEL MUSA for the M. S- in Organic Chemistry (Name) (Degree) (Major) Date thesis is presented July 2, 19 65 Title CHEMISTRY OF CYCLOBUTANE COMPOUNDS Abstract approved (Major professor) Examination of a proposed reaction scheme to prepare bicyclo- (2. 2. 0)hexan-l-ol produced the first known condensation of an enamine with its carbonyl precursor. Hydrolysis of the resulting dienamine gave an unusual conjugated cyclobutenone in which the double bond is exocyclic. Characterization and reactions of the cyclobutenone were successfully carried out. CHEMISTRY OF CYCLOBUTANE COMPOUNDS by WILLIE EDSEL MUSA A THESIS submitted to OREGON STATE UNIVERSITY in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE June 1966 APPROVED: Assistant Professor of Chemistry In Charge of Major Chairman of"Dep"artment of Chemistry Dean of Graduate School Date thesis is presented =£ \ A(ltr5 IT Typed by Susan Carroll ACKNOWLEDGEMENT The author wishes to express his appreciation to Dr. F..

  • Chapter 8 Alkyl Halides and Elimination Reactions
    Organic Chemistry, Second Edition Janice Gorzynski Smith University of Hawai’i Chapter 8 Alkyl Halides and Elimination Reactions Prepared by Rabi Ann Musah State University of New York at Albany Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display. 1 8.1 General Features of Elimination • Elimination reactions involve the loss of elements from the starting material to form a new π bond in the product. 2 1 • Equations [1] and [2] illustrate examples of elimination reactions. In both reactions a base removes the elements of an acid, HX, from the organic starting material. 3 • Removal of the elements HX is called dehydrohalogenation. • Dehydrohalogenation is an example of β elimination. • The curved arrow formalism shown below illustrates how four bonds are broken or formed in the process. 4 2 • The most common bases used in elimination reactions are negatively charged oxygen compounds, such as HO¯ and its alkyl derivatives, RO¯, called alkoxides. 5 • To draw any product of dehydrohalogenation—Find the α carbon. Identify all β carbons with H atoms. Remove the elements of H and X from the α and β carbons and form a π bond. 6 3 8.2 Alkenes—The Products of Elimination • Recall that the double bond of an alkene consists of a σ bond and a π bond. 7 • Alkenes are classified according to the number of carbon atoms bonded to the carbons of the double bond. Figure 8.1 Classifying alkenes by the number of R groups bonded to the double bond 8 4 • Recall that rotation about double bonds is restricted.
