The molecular precursor approach to control the morphology of Co₃O₄ on support materials
(University of St Andrews, 2011-11-14) - Thesis
In this project, the TMP method was employed to produce “active sites.” These active sites are for influencing and controlling the Co₃O₄ growth. One of the aims was to investigate what effect the grafting of the molecular ...
A new reversible 1,3-dipolar cycloaddition and its application in dynamic covalent chemistry
(University of St Andrews, 2016-05) - Thesis
In the past decades, chemists have designed and investigated artificial self-replicating molecules. A self-replicating molecule is one that can assemble its building blocks through molecular recognition, the building ...
The reactions of aromatic amines with 1,2-quinones
(University of St Andrews, 1971) - Thesis
Applications of NHCs and isothioureas as Lewis base organocatalysts
(University of St Andrews, 2013) - Thesis
This thesis details investigations into two modes of organocatalytic enolate generation and reactivity. The first is the addition of chiral NHCs to a ketene to form an azolium enolate. Investigations into three different ...
Controlling crystal growth of platy porous materials as potential substrates for effects pigments
(University of St Andrews, 2012) - Thesis
The mesoporous silica SBA-15 (SBA = Santa Barbara) has been prepared with a hexagonal platy morphology, particle sizes 8 µm × 0.5 µm thick, of interest as a substrate for effects pigments. Starting from a literature ...
The promoting role of Au in the Pd-catalysed synthesis of vinyl acetate monomer
(University of St Andrews, 2007-07-20) - Thesis
The reactivity of some organophosphorus esters
(University of St Andrews, 1969) - Thesis
Part 1: The occurrence of bimolecular nucleophilic aromatic substitution has been established in the reaction of o-dinitrobenzene with triethyl phosphite and diethyl methylphosphonite in acetonitrile solution. There is a ...
Enantioselective homogeneous catalysts for the synthesis of fluorinated organic compounds
(University of St Andrews, 2011-06) - Thesis
This thesis is divided into three main results chapters that reflect the path my research took. In the first results chapter, the first organocatalyst for the carbonyl-ene reaction was discovered and found to give high ...
N-Oxides from substitued o-nitroanilines
(University of St Andrews, 1998) - Thesis
The aim of this project was to investigate the cyclisation reactions of some o-nitroaryl derivatives of amino acids, with a view to the synthesis of potentially biologically active heterocyclic compounds. Chapter one is ...
Synthesis of novel heterocyclic polymers
(University of St Andrews, 1987) - Thesis
This work details the synthesis, characterisation and fabrication of a range of copolyesters, containing various angular disrupters, especially disubstituted 2,5-diphenyl- -1,3,4-oxadiazoles. These disrupters were incorporated ...
