    TDC Part I Paper I, Group B Inorganic Chemistry Department of Chemistry L.S COLLEGE MUZAFFARPUR B. R. A. BIHAR UNIVERSITY Dr. Priyanka TOPIC:- ORGANOLITHIUM REAGENT Organolithium reagent Organolithium reagents are organometallic compounds that contain carbon – lithium bonds. They are important reagents in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation Organolithium reagents are used in industry as an initiator for anionic polymerization, which leads to the production of various elastomers. They have also been applied in asymmetric synthesis in the pharmaceutical industry. Due to the large difference in electronegativity between the carbon atom and the lithium atom, the C-Li bond is highly ionic. This extremely polar nature of the C- Li bond makes organolithium reagents good nucleophiles and strong bases.These reagents are highly reactive, sometimespyrophoric, and should be handled with extreme caution. chemists found that in comparison with Grignard reagents, organolithium reagents can often perform the same reactions with increased rates and higher yields, such as in the case of metalation. Since then, organolithium reagents have surpassed Grignard reagents in usage. Structure: Although simple alkyllithium species are often represented as monomer RLi, they exist as aggregates (oligomers) or polymers. Their structures depend on the nature of organic substituent and the presence of other ligands. Nature of carbon-lithium bond A simplistic look at the large difference in electronegativity suggests the C-Li bond to be highly ionic.[ Certain organolithium compounds possess properties such as solubility in nonpolar solvents that complicate the issue.

  • Organometallic Chemistry
    ORGANOMETALLIC CHEMISTRY 1 Organometallic Chemistry (Prelude) What is Organometallic Chemistry? Organometallic chemistry refers to reactions that use the classes of compounds (R-M) that contain a covalent bond between carbon and a metal. They are prepared either by direct reaction of the metal with an organic compound (metallation) or by replacement of a metal in an organometallic compound with another metal (transmetallation). 12:44 PM 2 Organometallic Chemistry Why Go Organometallic Chemistry What is so special about the Organometallic approach to organic synthesis? Classical organic syntheses that proceed by the SN2 pathway require a strong nucleophile attacking an electrophilic site to be effective. Such reactions are of limited scope. For instance, the formation of biaryl systems via the classical substitution reaction is difficult to achieve. 12:44 PM 3 Organometallic Chemistry Applications Organometallic chemistry offers a way out of this dilemma. Through special organometallic reactions, a variety of carbon-carbon bonds can be formed and even biaryl systems can be readily synthesized. This possibility has expanded the scope of their use in organic synthesis since bonds that were hitherto difficult to form through the classical syntheses can almost now be routinely formed. Organometallic chemistry can make possible the synthesis of 12:44 PM pharmacologically relevant natural products containing biaryl units. 4 Organomagnesium or Grignard Reagents R-Mg-X The use of organometallic reagents in organic synthesis began around 1899 when Victor Grignard discovered that alkyl halides reacted with magnesium metal in diethylether to give homogenous solutions. The Grignard reagents proved to be very reactive carbanion nucelophiles and strong bases capable of abstracting highly acidic protons attached to heteroatoms such as O, N and S, and have remained very useful synthetic reagents ever since.

ReceiuedJuly 14, 1973 Abstract: The product mixtures obtained by reaction between phenyllithium and carbon monoxide in diethyl ether, followed by hydrolysis, include benzophenone (1). a,a-diphenylacetophenone(2), benzil (3), a,a-diphenyl- a-hydroxyacetophenone (4), benzpinacot (5), a-hydroxyacetophenone (6), 1,3,3-triphenylpropane-1,2-dione(7), 1,3,3-triphenylpropan-1-one-2,3-diol(8). and benzhydrol (9). Compounds 1, 2, 6,7, and 8 are produced in signifi- cant yields i 3,4,5, and 9 are produced in trace quantities. Spectroscopicstudies establish dilithium benzophenone dianion (18) as the first long-lived intermediate formed in this reaction; qualitative correlations betweenthe basicity of a number of organolithium reagentsand their reactivity toward carbon monoxide suggests,but does not prove, that benzoyllithium is a precursor of 18. Labeling experiments indicate that the products ultimately isolated following hydrolysis of the reaction mixture are derived from at least two pathways which compete for the initially formed 18. One involves combination of l8 with 1 equiv of phenyllithium and 1 equiv of carbon monoxide, followed by elimination of I equiv of lithium oxide. yielding 17, the lithium enolateof 2; a secondinvolves com- bination of 18 with 1 equiv of phenyllithium and 2 equiv of carbon monoxide.

  • Writing Reaction Mechanisms in Organic Chemistry by Audrey Miller, Philippa H
    Writing Reaction Mechanisms in Organic Chemistry by Audrey Miller, Philippa H. Solomon · ISBN: 0124967124 · Publisher: Elsevier Science & Technology Books · Pub. Date: November 1999 PREFACE TO THE SECOND EDITION In revising this text for the second edition, a major goal was to make the book more user-friendly for both graduate and undergraduate students. Introductory material has been fleshed out. Headings have been added to make it easier to locate topics. The structures have been redrawn throughout, with added emphasis on the stereochemical aspects of reaction mechanisms. Coverage of some topics such as solvent effects and neighboring group effects has been expanded, and Chapter 6 has been completely reorganized and extensively rewritten. As in the previous edition, the focus of this book is on the how of writing organic mechanisms. For this reason and to keep the book compact and portable, the number of additional examples and problems has been mini­ mized, and no attempt has been made to cover additional topics such as oxidation-reduction and organotransition metal reactions. The skills devel­ oped while working through the material in this book should equip the reader to deal with reactions whose mechanisms have been explored less thoroughly. I am most grateful to the reviewers, who gave so generously of their time and experience in making suggestions for improving this book. Particular thanks go to series editor Jim Whitesell, who cast his eagle eye over the numerous structures and contributed to many stimulating discussions. Thanks also to John DiCesare and Hilton Weiss, and to John Murdzek, who meticu­ lously annotated the entire manuscript both before and after revisions.

    PREPARATION AND USE OF ALKALI METALS (Li AND Na) IN ALUMINA AND SILICA GEL AS REAGENTS IN ORGANIC SYNTHESES By Fatmata Jalloh A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Chemistry – Doctor of Philosophy 2017 ABSTRACT PREPARATION AND USE OF ALKALI METALS (Li AND Na) IN ALUMINA AND SILICA GEL AS REAGENTS IN ORGANIC SYNTHESES By Fatmata Jalloh This work describes the development of alkali metals (Li and Na) encapsulated in silica and alumina gel (SG and AG), and their applications in organic syntheses. The methods elucidated involved the thermal incorporation of these metals into the pores of SG and AG, serving as solid- state reagents. The encapsulation method/approach addresses the problems associated with the high reactivity of these metals that limit their synthetic utility in research laboratories, pharmaceutical, and manufacturing industries. These problems include their sensitivity to air and moisture, pyrophoricity, difficulty in handling, non-commercial availability, and instability of some of the organoalkali metals reagents. Herein, we describe the developments to synthesize alkali metal precursor (Li-AG) in solid form that offer safer organolithium reagents. This precursor reduces or eliminates the danger associated with the traditional handling of organolithium reagents stored in flammable organic solvents. The use of Li-AG to prepare and deliver organolithium reagents from organic halides and ethers, as needed especially for those that are commercially not available is put forward. In addition, exploration of additional applications of Na-SG and Na-AG reagents in the demethoxylation of Weinreb amides to secondary amines, and Bouveault-Blanc type reduction of amides to amines are described.

Construction of silacyclic skeletons via metal-mediated or catalyzed Si–C bond cleavage has attracted much recent attention. Several interesting and useful synthetic strategies have been reported in the literature. In this review, we have summarized recent developments on metal-mediated or catalyzed Si–C bond cleavage, which lead to the synthesis of silacycles, including silacyclobutenes, silacyclopentanes, silacyclo- pentadienes (siloles), 6-membered silacycles, and their derivatives.

Chin Sci Bull, 2013, 58: 307315, doi: 10.1007/s11434-012-5351-4 Silacycles, especially silole and related compounds have mediated SiC bond formation, the first example of for- received growing interest as potential electroluminescent mation of silacycles via SiC bond cleavage was found with materials [1–9]. Conventional synthesis of silacycles is ach- the reaction of dilithio reagent with monhalosilane. More ieved by silylation of organometalic compounds, such as than 50 years ago, Gilman and co-workers [22–24] reported RLi or RMg, with dihalo or tetrahalosilanes [10–18].
