C-N bond formation employing palladium and nickel precatalysts containing anionic phosphinobenzimidazole ligands
(2016)In this investigation, the catalytic utility of anionic, phosphinobenzimidzoles [Li(THF)2][1a] and [Li(THF)4][1b] in effecting the Buchwald-Hartwig amination reaction was examined. Specifically, the coordination chemistry ... -
Complexes of ethylxanthate and N, N-diethyldithiocarbamate and their adducts with some nitrogen bases
This thesis concerns first row transition metal complexes of ethylxanthate and diethyldithiocarbamate (dtc). Complexes of the type M(Xan)2 and (see document for formula) have been prepared and studied. It was found that ... -
Computational tools for the high-throughput identification of protein-targeted drugs and probes
(2015-08-04)This thesis is comprised of three projects that are driven by a common theme, which is the use of computational tools in aiding molecular probe and drug design. In the first project, the feasibility of using molecular ... -
Constructing two-dimensional molecular networks on metal and semiconducting surfaces : a scanning tunneling microscopy study
(2019)The synthesis of two-dimensional organic nanostructures on metal and semiconducting surfaces is studied under ultra-high vacuum (UHV) conditions. Three halogenated organic molecules are investigated using scanning tunneling ... -
Coordination chemistry of bithiazole ligands: a comparative study of the 2,2’ and 4,4’ isomers
(2019)The bithiazole ring system consists of two thiazole (C3NS) aromatic rings. There are many regioisomers but two of potential interest for coordination chemistry are the 2,2’-bis(1,3-thiazole) and the 4,4’-bis(1,3-thiazole), ... -
Copolymerization of pretreated kraft lignin and acrylic acid to produce flocculants for suspension and solution systems
(2017)The presence of dyes in the wastewater of textile industry poses a number of environmental concerns due to their toxic nature and the removal of dyes from the wastewater is a major challenge nowadays. Synthetic polymers ... -
Cross-coupling reactions: synthesis and photoactivity of enediynes
(2015-02-02)The syntheses of a number of photoactive enediynes using the Sonogashira Coupling reaction are described. Alkynes with different characteristics were coupled to 2-bromoiodobenzene to yield the desired drugs. The enediyne’s ... -
Decomposition of 2-propanol over vanadium pentoxide and modified vanadium pentoxide catalysts
