9th Ferrocene Colloquium February 14 – 16, 2011 Sponsors The 9th Ferrocene Colloquium would not be possible without the generous support of our spon- sors. We are grateful to: ii “Die Chemie ist, abgesehen von ihrer Nützlichkeit, die niemand bestreiten wird, eine schöne Wissenschaft.” “Chemistry is apart from its usefulness, which no one will deny, a beautiful science.” Julius Adolph Stöckhardt (1809–1886) 1st Professor for Chemistry in Chemnitz Table of Contents Preface............................................ vii Previous Meetings...................................... viii Organizing Committee ................................... viii Schedule........................................... ix Invited Speakers....................................... 1 Oral Presentations...................................... 7 Poster Presentations..................................... 33 List of Participants ..................................... 63 v Preface Almost 60 years after its unintended discovery, ferrocene still arouses great interest among scientists in many areas of research. The wide spectrum of applications is reflected in many different topics the 9th Ferrocene Colloquium is dedicated to. During the next three days, young researchers along with outstanding scientists will present recent results of their research, for ex- ample the synthesis of new ferrocene molecules and materials, the application of metallocenes in catalysis or electron transfer studies as well as the investigation of hitherto unknown reactiv- ities. In the past years the Ferrocene Colloquium has become a full meeting primarily for young researchers in the field of organometallic chemistry with main focus on metallocenes. It gives me great pleasure to welcome more than 100 participants to the 9th Ferrocene Colloquium, who will present more than 20 lectures together with many posters. This meeting would not be possible without the financial and material support of our spon- sors.

[email protected] The design, preparation, and characterization of new electro-functional materials containing transition metals hybridized with other substances containing various elements constitute a very active field of basic and applied research. A particularly appealing class of composite molecules can be obtained by linking two redox-active inorganic building blocks with unsaturated organic ligands [1]. These molecules can be isolated in several oxidation states, each of them exhibiting different physical properties, like for example, photoluminescence [2], photo-induced electron transfer, hyperpolarizability or magnetic properties [3]. These physical properties can be easily switched on or off by a single electron transfer. Very recently, we prepared and investigated new molecules that incorporate redox active building blocks into carbon-rich bridges between the terminal iron centers with d5 and d6 elec- tronic configurations [4–5]. Physical properties of these new compounds were investigated in regard to their merit to mediate electron transfer and magnetic coupling interactions [1] Paul, F.; Lapinte, C. Coord. Chem. Rev. 1998, 427, 178. [2] Samoc, M.; Gauthier, N.; Cifuentes, M.P.; Paul, F.; Lapinte, C.; Humphrey, M.G. Angew. Chem. Int. Ed. 2006,

  • Organometallic and Catalysis

    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.

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.

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.

X-ray crystallographic polymerization as a highly active singlecomponent catalyst.5b analysis of this complex revealed a zwitterionic structure However, the reported group 4 metal catalyst systems with a consisting of cationic alkylzirconium chloride and four-coordinated pendent aluminum-based Lewis acidic moiety were limited,6 aluminate. In the presence of catalytic amount of this complex, while the aluminum additives have been commonly used in ethylene polymerization could proceed without any additives to Kaminsky catalyst. Nomura reported utilization of titanium t form ultra-high molecular weight polyethylene. complex bearing Me2Al(O Bu)(OR) moiety as a single- component catalyst for ethylene polymerization (Scheme In homogeneous catalytic polymerization of olefins, an 1B).6a,b In their plausible mechanism, the dissociation of admixture of group 4 transition-metal complex, such as Me2Al(OtBu)(OR) moiety as an anion generates zwitterionic metallocene or halfmetallocene complexes, and Lewis acidic complex involving cationic titanium centre. This catalyst additive, have been known to construct an effective catalyst system can form high molecular weight PE (> 1,000,000) due 1 system, represented as Kaminsky catalyst.
