Copolymerization studies of ethylene and trimethylsilyl protected 1-alkenols using a Brookhart-type alpha-diimine nickel(II) dibromide precatalyst
Murray, Heidi (2009-02-02)There has been considerable interest over the past decade in the preparation and applications of copolymers of ethylene with functionalized polar olefins. Such copolymers are expected to exhibit a variety of potentially ... -
Incorporation of Polar Comonomers Into High Density Polyethylene With a Cyclopentadienyl-Amido Titanium Catalyst
Vettese, Gregory (2009-04-27)The purpose of this research was to synthesize the constrained geometry catalyst Ti[(C5Me4)SiMe2(tBuN)]Cl2 (1) with MAO as a cocatalyst for ethylene homopolymerization and copolymerizations with 1-TMSO-alkenes to produce ... -
INVESTIGATIONS OF A NEW AND IMPROVED PRECATAYLST FOR PALLADIUM CATALYZED CROSS COUPLING REACTIONS
Fraser, Andrew (2013-07-02)Little attention has been given to the formation of the putative PdL2 species required for Pd-catalyzed cross-coupling reactions. Active species are generally difficult to store due to air-sensitivity and are therefore ... -
Late and early transition metal-catalyzed homo and copolymerizations studies of olefins and polar monomers
Stojcevic, Goran (2008-03-03)The aims of this work were two-fold. The first part of this thesis involves the synthesis of the Brookhart’s diimine catalyst [Pd(N-N)Me(Et2O)]+ (1) (N-N = (2,6-(i-Pr)2C6H3)-N=CH2CH2=N-(2,6-(i-Pr)2C6H3)) and an ... -
A new, improved precatalyst for Suzuki-Miyaura cross-coupling reactions
Norton, Danielle (2009-07-23)Carbon-carbon bond formation is one of the most important reactions in organic chemistry, and the Suzuki-Miyaura cross-coupling reaction has become a forerunner in this area. Considerable research has been directed at the ... -
NOVEL GROUP 4, 9, 10, AND 12 COMPLEXES OF INDENYL-DERIVED YLIDES
Purdavaie, Kourosh (2015-06-02)The coordination chemistry of the phosphonium-1-indenylide (PHIN) ligand methyldiphenylphosphonium-1-indenylide (1-C9H6PMePh2, I) has been studied, and a new phosphonium-1-indenylide (PHIN) ligand methyldiphenylphosphoni ... -
Novel group 6 complexes of cyclopentadienylidene ylides
Brownie, John Hugh (2007-09-12)Abstract Methyldiphenylphosphonium cyclopentadienylide, C5H4PMePh2 (II), has been synthesized and characterized spectroscopically and crystallographically, and has been found to exhibit properties consistent with the ... -
A novel series of titanocene dichloride derivatives: synthesis, characterization and assessment of their cytotoxic properties
Potter, Gregory David (2008-05-15)Although cis-PtCl2(NH3)2 (cisplatin) has been widely used as a chemotherapeutic agent, its use can be accompanied by toxic side effects and the development of drug resistance. Consequently, much research has been focused ... -
Oxyfunctionalization of Polystyrene Using Non-Heme Iron Catalysts
McArthur, Shelley (2011-08-15)The non-polar nature of polystyrene has allowed this material to be widely used in both industrial and household applications. This same property also limits its interactions with polar materials and its stability renders ... -
Palladium and Ruthenium Catalyzed Reactions
Jaksic, Bryan (2011-07-05)Part one of this thesis will discuss research which involves the direct comparison of the activity of commonly used precatalysts with the newly synthesized precatalyst, Pd(η5-C5H5)(η3-1-Ph-C3H4), for Sonogashira cross-coupling ... -
STRUCTURE AND PROPERTIES OF SOME α-, β- AND γ-AGOSTIC ALKYL-TITANOCENE COMPLEXES
Dunlop-Brière, Alexandre (2014-12-23)In chapter 2, the synthesis and NMR characterization of [Cp2TiCH3(H2O)]+ (I) is presented. In the presence of excess water, there is evidence of rapid H-exchange and H-bonding between coordinated and free water. At higher ... -
Studies In the Optimization of the Suzuki-Miyaura Reaction
Mitchell, Emily (2008-12-10)Enormous efforts have been made to optimize the Pd-catalyzed Suzuki-Miyaura reaction, but there is to date no generally useful protocol and forcing conditions are often required. One reaction variable that has often been ... -
STUDIES ON THE OPTIMIZATION OF BUCHWALD-HARTWIG AMINATION OF ARYL HALIDES
Borjian Borojeni, Sogol (2014-09-29)Developing new catalyst systems for cross-coupling reactions such as Buchwald-Hartwig aminations has been one of the remarkable topics in the palladium-catalyzed, cross-coupling reaction research area. In this thesis, the ... -
The syntheses and characterization of nickel complexes; investigation of Ni(dppp)2 and [NiX(dppp)n]x, potentially catalytically active nickel(0)/(I) species for cross-coupling reactions
Mehder, Rozan H. (2016-05-30)This thesis describes an investigation in which we compare Ni(0), Ni(I) and Ni(II) complexes containing 1,3-bis(diphenylphosphino)propane (dppp) as a phosphine ligand for their abilities to effect three types of cross-coupling ... -
