    SOME STUDIES ON CYCLOPENTADIFNYL AND CARBONYL COMPLEXES OF TRANSITION METALS. A Thesis submitted by JON ARMISTICE McCLEVERTY, B.Sc. for the Degree of Doctor of Philosophy of the University of London. Royal College of Science. May 1963. This Thesis I dedicate to DIANNE. Her love and understanding is a continual inspiration. kit CHAPTER II ic-CYCLOPENTADIENYL METAL HYDRIDES THE DI-n-CYCLOPENTADIENYL HYDRIDES OF TANTALUM MOLYBDENUM. AND TUNGSTEN. The hydride complexes are prepared in high yields by the inter- action of the anhydrous metal chlorides (Noel" 1C16, or TaC15) with a solution of sodium cyclopentadienide in tetrahydrofuran containing an excess of sodium borohydride. Without addition of borohydride to the sodium cyclopentadienide solution only low yields of the hydrides can be obtained since the hydriue ion required must come from the solvent or from traces of excess of cyclopentadiene or cyclopentene present in the reaction mixture. The tantalum hydride, (n-C5H5)2TaH3, is a white crystalline compound which is sensitive to air; the molybdenum and tungsten hydrides, (n-05H5)2MH2, form yellow crystals, the former being more sensitive to air than the latter, which can be handled briefly in air. The tantalum compound is sparingly soluble in light petroleum but it is moderately soluble in benzene; the other hydrides are soluble in light petroleum as well as in other common solvents. Solutions of all three compounds decompose rapidly wren exposed to air. The compounds are soluble in halogenated solvents and in carbon disulphide but react with them quite rapidly, the order of reactivity being Ta Mo ACKNOWLEDGMENTS I would like to express my deep gratitude to Professor G.

  • N-Metal Compounds
    31 N-METAL COMPOUNDS n the 85 years following Kekulk's brilliant proposal for the structure of ben- zene, organic chemistry underwent a tremendous expansion, and in the process a wide variety of paradigms or working hypotheses were developed about what kinds of compounds could "exist" and what kinds of reactions could occur. In many cases, acceptance of these hypotheses appeared to stifle many possible lines of investigation and caused contrary evidence to be pigeonholed as "interesting but not conclusive." As one example, the paradigm of angle strain was believed to wholly preclude substances that we know now are either stable or important reaction intermediates, such as cubane (Section 12- 1O), cyclo- propanone (Section 17-1 I), and benzyne (Sections 14-6C and 23-8). No paradigm did more to retard the development of organic chemistry than the notion that, with a "few" exceptions, compounds with bonds between carbon and transition metals (Fe, Co, Ni, Ti, and so on) are inherently un- stable. This idea was swept away in 1951 with the discovery of ferrocene, (C,H,),Fe, by P. L. Pauson. Ferrocene has unheard of properties for an organoiron compound, stable to more than 500" and able to be dissolved in, and recovered from, concentrated sulfuric acid! Pauson's work started an avalanche of research on transition metals in the general area between organic and inorganic chemistry, which has flourished ever since and has led to an improved understanding of important biochemical processes. 31-1 Metallocenes 31-1 METALLOCENES The discovery of ferrocene was one of those fortuitous accidents that was wholly unforeseeable- the kind of discovery which, over and over again, has changed the course of science.

Farrugia MSc Core Course C5 Text books : Inorganic Chemistry - Housecroft & Sharpe Ch 23 - the very basics Inorganic Chemistry - Shriver & Atkins Ch 16 - the very basics This course assumes familiarity with the Level-2 and Level-3 courses on Organometallic Chemistry, and this is covered in the above texts Organometallics - Elschenbroich & Salzer (library) - much more useful Topic 1 - Introduction to Cyclopentadienyl Compounds First part of course covers the role of the ligand cyclopentadienyl (Cp) and its derivatives. Cp is one of the most important ligands in organometallics after CO. A considerable percentage of organometallic compounds contain this ligand - it is also a good ligand for main group metals and the f-block metals (lanthanides & actinides). H H H Fe CO H OC CO Cyclopentadiene Cyclopentadiene complex (4 e donor ligand) very rare as a ligand Na / -H2 H - Na+ H acidic H atom planar aromatic (6-pi electron) dienyl anion - The anion C 5H5 is a very useful synthetic reagent. It is usually treated as equivalent to occupying THREE coordination sites, so that C 5H5 ≡ 3(CO). In electron counting terms, it can be treated as either as a 6-e donor ANION or a 5- e donor NEUTRAL molecule. The latter is the recommended approach because it is simpler (do not need to worry about oxidation levels). 1.1 Bonding in cyclopentadienyl compounds Cp has 5 π electrons in the 5 out-of-plane p-orbitals on the C atoms. These 5 orbitals combine as a 1 + e 1 + e 2 under five-fold symmetry.
