Rossin, Joseph A. "Synthesis, characterization and reactivity of transition metal containing zeolites." Diss., Virginia Polytechnic Institute and State University, 1986. http://hdl.handle.net/10919/76271.

Full text

Abstract:

Transition metal containing zeolites (zeolite A and ZSM-5) were prepared by addition of various transition metal containing substrates to zeolite synthesis gels. Crystal growth data were recorded in order to determine the influence of the transition metal species on the rate of crystal growth. X-ray diffraction, oxygen adsorption, FTIR and SEM were utilized to evaluate crystal purity. X-ray photoelectron spectroscopy (XPS), chemical analysis and electron microprobe analysis were performed in order to ascertain the position (intrazeolitic versus surface) and homogeneity of the transition metal.

Abstract:

The work in this thesis is mainly concerned with the discussion of effect of solvation on the reaction kinetics of inorganic complexes. Rate constants for chemical reactions in various aqueous cosolvent systems have been measured and analysed. Crystal structure of several Fe (II) complexes are analysed from crystallographic data for possible structural parameters which might have effect on solvation. Solubility data, for a range of inorganic salts containing simple and complex ions, are reported for aqueous solutions and for solutions in aqueous cosolvent mixtures. Transfer chemical potentials

Abstract:

The new μ-(l,n)-alkanediyl compounds [(ƞ⁵-C₅R₄Me)Fe(CO)₂ ]₂{μ-(CH₂)n}, (R = H, n = 3 -10 and R =Me, n =3 - 6), [Mn(CO)₅]₂{μ-(CH₂)n} (M = Mn, n = 4-6 and M = Re, n= 3 and 4) have been prepared using essentially two synthetic routes. Thus the iron compounds were synthesized by the reaction of Na[(ƞ⁵-C₅R₄Me)Fe(CO)₂ ] with the appropriate dibromoalkane. The manganese and rhenium compounds on the other hand, were prepared by the decarbonylation of the corresponding diacyl compounds of the type, [M(CO)₅]₂{μ-CO(CH₂)nCO} (M = Mn or Re).

A range of computational and experimental techniques have been applied to the study of four metal cluster systems. Decorated rhodium clusters Rh n O m (N 2 O) + ( n = 4 − 8, m = 0 − 2) have been investigated both experimentally by IR-MPD and computationally using DFT. The effect of cluster size as well as oxygen coverage on the spectroscopy of the N 2 O bend are analyzed. The infrared-induced decomposition of N 2 O on Rh n O + m is observed on all cluster sizes, with marked differences as a function of size and oxygen coverage, particularly in the case of Rh 5 (N 2 O) + .

Abstract:

High-valent terminal metal-oxygen adducts are supposed to be potent oxidising intermediates in enzymatic catalyses. In contrast to those from groups 6-8, oxidants that contain late transition metals (Co, Ni, Cu) are poorly understood. Because of their high reactivity, only a few examples of these compounds have been observed. The aim of this project was to investigate the reactivity of high-valent Ni(III) complexes, containing a monodentate oxygen-donor ligands, in hydrogen atom abstraction (HAA) and oxygen atom transfer (OAT) reactions which are typical of biological high-valent metal-oxygen

Abstract:

L’objectif de ce travail est la synthèse de complexes contenant des ligands NHC protiques fonctionnalisés avec un groupement imine dans le but de développer des méthodologies de synthèse donnant accès à des ligands pNHC ainsi que la synthèse des groupes imidazolide anioniques liés par le C et leurs complexes homo et hétéro-dinucléaires. Dans le cas des imidazoles sans groupe fonctionnel, la déprotonation à l’aide de n-butyl lithium a permis l’obtention de (1-aryl-1H-imidazol-2-yl)lithium avec de bons rendements. La réaction de (1-aryl-1H-imidazol-2-yl)lithium avec [Ir(cod)(μ-Cl)]2 ou [Rh(cod)(

Abstract:

The introduction reviews the importance of macrocyclic complexes particularly tetraazaannulenes in biological systems such as in haem, chlorophyll, P450 enzyme and vitamin B12 as well as displaying the variety of chemistry apparent in the diversity of uses and applications in other research fields. In Chapter Two the dibenzo- and dipyridotetraazaannulene ligands are prepared and characterized. Many of these ligands are reported here for the first time. Two distinct types of dibenzotetraazaannulene ligands were studied. Those with a saddle shaped structure such as H2L1, H2L2 and H2L3 and those
