High valent transition metal corrole and corrolazine complexes. The question of noninnocent ligands
(Master thesis; Mastergradsoppgave, 2003-06-06)To contribute to the fundamental picture of the electronic structure of high valent first row transition metal complexes, I have carried out a density functional study of two different macrocyclic ligand systems, corroles and corrolazines, with two different axial ligands, Ph and Cl and a number of different central ions, P(V), Cu(III), Mn(IV) and Fe(IV). DFT calculations on Fe(IV) and Mn(IV) corrole ... -

Syntese av klorerte fettsyrer til bruk som standarder i miljøanalyser
(Master thesis; Mastergradsoppgave, 2007-06-20)Mettede C-16 og C-18 klorerte fettsyrer ble syntetisert til bruk som miljøstandarder. De mettede klorerte fettsyrene hører sammen med en ny type miljøgift nemlig klorerte fettsyrer (ClFA). Dette er en type miljøgift som man per dags dato ikke har så mye kunnskap om, men som er blitt påvist i en rekke forskjellige fiskearter. Hvilken effekt de vil ha på mennesker eller andre pattedyr på toppen av ... -
Inhibition study of Vibrio cholerae Endonuclease I
(Master thesis; Mastergradsoppgave, 2008-05-15)The Vibrio cholerae bacteria resistance against introduction of new genetic material through transformation is caused mainly by a small extracellular or periplasmic endonuclease of type I, the VcEndA of 24.7 kDa coded by the dns gene, (Focareta et al, 1987; Focareta et al, 1991; Altermark et al, 2007b). The VcEndA homologues in other bacteria, Serratia marcescens (Timmins et al, 1973), Erwinia ... -
Bonding in a triamidoamine-supported chromium(III) carbonyl
(Master thesis; Mastergradsoppgave, 2008-05-15)Cr(III) metal ion in low spin triamidoamine-supported chromium(III) carbonyl complex {[(RN)3N]CrCO, 1} has a unique feature of S=1/2 being unusual for a Cr(III) metal ion, which is high spin with S=3/2 in most complexes and this gives us the basis for this theoretical study. The primary preoccupation has been to determine the electronic ground state and other low-energy state with much emphasis ... -
On the synthesis of a fimbrolide
(Master thesis; Mastergradsoppgave, 2008-06-30)The present work is on the total synthesis of a natural compound found in a mixture of secondary metabolite produced by an alga nearby the cost of Australia. The target molecule, the 4-bromo-3-butyl-5-(dibromomethylene)furan-2(5H)-one, has not previously been proposed. The synthetic route described in this thesis uses cheap and readily available starting materials and the target is reached after six ... -
Demetalation of metallocorroles
(Master thesis; Mastergradsoppgave, 2008-10)Although the chemistry of corroles has grown spectacularly in recent years, the field has been marred by the lack of convenient protocols for demetalation of metallocorroles. In this thesis, I have developed a superior procedure for demetalating copper corroles with concentrated H2SO4 and 5-200 equiv FeCl2 or SnCl2. The yields obtained with this reductive procedure are generally substantially ... -
On the synthesis of pyrylium salts
(Master thesis; Mastergradsoppgave, 2009-05-19)Abstract The present work is on the synthesis of a pyrylium salt, 8-hydroxy-2,4-diphenyl-5,6,7,8-tetrahydrochromenylium tetrafluoroborate, a precursor for interesting transition metal ligands. Different routes are presented with the aim of making an affordable precursor for the variety of syntheses possible from these versatile pyrylium salts. New findings include a preparative non optimized ... -
Potassium on potassium-graphite as reagent in the paal-knorr synthesis of 2,5-dimethylthiophene.
(Master thesis; Mastergradsoppgave, 2009-05-27)This thesis describes a new principle for the synthesis of thiophene from diketone. Thiophene is a five-membered heterocyclic aromatic compound containing one sulphur atom. The thiophene structure can be found in certain natural products and is also incorporated in several pharmacologically active compounds. The procedure described in the thesis uses the combination of graphite and metallic ... -
Identification, cloning and expressions of proteases from a cold adapted organism Aliivibrio salmonicida
(Master thesis; Mastergradsoppgave, 2009-07-27)The work presented in this thesis provides an overview of molecular and structural biology projects and their related problems. The problems arises during these projects are common for most of the target proteins, with varying intensity of severity. The realization and identification of these problems and selection of their correct, best possible solution is an imperative step that might lead to ...
