  • Organometallic and Catalysis
    ORGANOMETALLIC AND CATALYSIS Dr. Malay Dolai, Assistant Professor, Department of Chemistry, Prabhat Kumar College, Contai, Purba Medinipur-721404, WB, India. 1.Introduction Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkaline, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and tin, as well. Aside from bonds to organyl fragments or molecules, bonds to 'inorganic' carbon, like carbon monoxide (metal carbonyls), cyanide, or carbide, are generally considered to be organometallic as well. Some related compounds such as transition metal hydrides and metal phosphine complexes are often included in discussions of organometallic compounds, though strictly speaking, they are not necessarily organometallic. The related but distinct term "metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds but which contain organic ligands. In 1827, Zeise's salt is the first platinum- olefin complex: K[PtCl3(C2H4)].H2O, the first invented organometallic compound. Organometallic compounds find wide use in commercial reactions, both as homogeneous catalysis and as stoichiometric reagents For instance, organolithium, organomagnesium, and organoaluminium compounds, examples of which are highly basic and highly reducing, are useful stoichiometrically, but also catalyze many polymerization reactions. Almost all processes involving carbon monoxide rely on catalysts, notable examples being described as carbonylations. The production of acetic acid from methanol and carbon monoxide is catalyzed via metal carbonyl complexes in the Monsanto process and Cativa process. Most synthetic aldehydes are produced via hydroformylation. The bulk of the synthetic alcohols, at least those larger than ethanol, are produced by hydrogenation of hydroformylation- derived aldehydes.

  • Nbcl5-Mg Reagent System in Regio- and Stereoselective Synthesis of (2Z)-Alkenylamines and (3Z)-Alkenylols from Substituted 2-Alkynylamines and 3-Alkynylols
    molecules Article NbCl5-Mg Reagent System in Regio- and Stereoselective Synthesis of (2Z)-Alkenylamines and (3Z)-Alkenylols from Substituted 2-Alkynylamines and 3-Alkynylols Rita N. Kadikova *, Azat M. Gabdullin, Oleg S. Mozgovoj, Ilfir R. Ramazanov and Usein M. Dzhemilev Institute of Petrochemistry and Catalysis of Russian Academy of Sciences, 141 Prospekt Oktyabrya, 450075 Ufa, Russia; [email protected] (A.M.G.); [email protected] (O.S.M.); ilfi[email protected] (I.R.R.); [email protected] (U.M.D.) * Correspondence: [email protected] Abstract: The reduction of N,N-disubstituted 2-alkynylamines and substituted 3-alkynylols using the NbCl5–Mg reagent system affords the corresponding dideuterated (2Z)-alkenylamine and (3Z)- alkenylol derivatives in high yields in a regio- and stereoselective manner through the deuterolysis (or hydrolysis). The reaction of substituted propargylamines and homopropargylic alcohols with the in situ generated low-valent niobium complex (based on the reaction of NbCl5 with magnesium metal) is an efficient tool for the synthesis of allylamines and homoallylic alcohols bearing a 1,2-disubstituted double bond. It was found that the well-known approach for the reduction of alkynes based on the use of the TaCl5-Mg reagent system does not work for 2-alkynylamines and 3-alkynylols. Thus, this article reveals a difference in the behavior of two reagent systems—NbCl5-Mg and TaCl5-Mg, Citation: Kadikova, R.N.; Gabdullin, in relation to oxygen- and nitrogen-containing alkynes. A regio- and stereoselective method was A.M.; Mozgovoj, O.S.; Ramazanov, developed for the synthesis of nitrogen-containing E-β-chlorovinyl sulfides based on the reaction of I.R.; Dzhemilev, U.M.

Evaluation of these systems established rac-(ebthi)ZrF2 (1) and Cp2ZrF2 (3) together with i-Bu2AlH as active catalysts in the room-temperature hydrodefluorination (HDF) of pentafluoro-pyridine. The active species for the conversion were the actually formed hydrides [rac-(ebthi)ZrH(␮-H)]2 (2) and [Cp2ZrH(␮-H)]2 (4). The results we obtained (rt, 24 h, turn over number 67) showed a significantly better performance compared to other investigations published before for this HDF reaction. © 2006 Elsevier B.V.

  • Reactions of Alkyl and Alkenyl Zirconocene Complexes
    Reactions of alkyl and alkenyl zirconocene complexes by Klark Thor Hanson A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Chemistry Montana State University © Copyright by Klark Thor Hanson (1992) Abstract: Zirconacycles have been. demonstrated to react sluggishly with acyl chlorides even at elevated temperatures . Studies were undertaken to detertmine whether or not this reaction could be facilitated via transmetallation of one or both of the carbon-zirconium bonds of the zirconacycle to a more suitable metal. This research demonstrates that zirconacycles will react with acyl chlorides in the presence of secondary metallic reagents. Cuprate reagents and catalytic palladium complexes have been demonstrated to function in this capacity, presumably via stoichiometric and catalytic transmetallation respectively.

Naturforsch. 50b, 469-475 (1995); received September 20, 1994 Homogeneous Ziegler Catalyst, Isotactic Polypropylene, Ansa-Metallocene, Fulvene 2,5-Hexanedione was converted into the bisfulvene 2, then treated with two molar equiva­ lents of methyllithium to yield the [4-cyclopentadienylidene-4,7,7-trimethyl-4,5,6,7-tetra- hydroindenyl]dilithio compound 4. Hydrolysis, followed by treatment with acetone/pyrroli­ dine, gave the corresponding fulvene system 5. Reaction of 5 with methyllithium followed by treatment with ZrCl4 furnished the ring-annulated Cr bridged ansa-metallocene 8, bearing a tert-butyl substituent at the Cp ring, as a 1:1 mixture of two diastereoisomers. Treatment of the fulvene 5 with LiAlH4 followed by ZrCl4 yielded the respective isopropyl-substituted ansa-metallocene diastereomers 9a and 9 b. Com plex 9 b was separated by fractional crys­ tallization and characterized by X-ray diffraction. Complexes 8 and 9 provide active homo­ geneous Ziegler-type catalyst systems upon activation with excess methylalumoxane produc­ ing low molecular weight isotactic polypropylene with high catalyst activities. Introduction Homogeneous group 4 bent metallocene methylalumoxane-derived Ziegler-type catalyst systems have become of enormous importance for the development of a-olefin polymerization [ 1], Most of the catalyst systems of practical impor­ tance are derived from ansa-metallocene precur­ I sors [2].

Zirconocene complexes immobilised on solid polymethylaluminoxane (sMAO) (sMAO–Cp2ZrX2), have been investigated using SEM-EDX, diffuse reflectance FT-IR (DRIFT) and high field (21.1 T) solid state NMR (ssNMR) spectroscopy.

We report evidence for X group transfer from the precatalyst complex onto the surface of the rsc.li/frontiers-materials aluminoxane support, which in the case of X = C6F5, results in a 38% increase in activity.

    UNIVERSITY OF CALIFORNIA Los Angeles Ferrocene-Chelating Heteroscorpionate Ligands Support Zinc Complexes as Redox Switchable Catalysts A thesis submitted in partial satisfaction of the requirements for the degree Master of Science in Chemistry by Tate Christopher Reuter 2018 © Copyright by Tate Christopher Reuter 2018 ABSTRACT OF THE THESIS Ferrocene-Chelating Heteroscorpionate Ligands Support Zinc Complexes as Redox Switchable Catalysts by Tate Christopher Reuter Master of Science in Chemistry University of California, Los Angeles, 2018 Professor Paula Loredana Diaconescu, Chair Ferrocene-chelating heteroscorpionate compounds based on [fc(PPh2)(BH[(3-R-5-R'-1-H)2pz]2)] (fc = 1,1'-ferrocenediyl, pz = pyrazole) are studied and characterized for their role in the synthesis of block copolymers. The ferrocene scaffold is part of a heteroscorpionate ligand that supports late transition metals. A zinc complex, [fc(PPh2)(BH[(3,5-Me-1H)2pz]2)]Zn(μ-OCH2Ph), was synthesized previously and shown to exist in a dimeric state. Herein, the substituents on the pyrazole fragments of the scorpionate are replaced with bulkier groups to force the formation of a monomeric compound in order to arrive at a redox switchable catalyst. ii The thesis of Tate Christopher Reuter is approved.

Kaner Ellen May Sletten Paula Loredana Diaconescu, Committee Chair University of California, Los Angeles 2018 iii This work is dedicated to my loving family and those making a sacrifice to better themselves and the world we share. iv TABLE OF CONTENTS Abstract ii
