Micelle Enhanced Analytical Chemistry
The ability of surfactant micellar aggregates to enhance collisional quenching between a model cation analyte, copper (II) ion, and two fluorescent probes, phenosafranin and N-methylacridone (NMA), was studied. The intensity of the fluorescence emission observed from these two probe molecules was …

Studies in pyrimidine chemistry.
The synthesis of a series of 2-chloro-5-(hetero)arylpyrimidines and 5-(hetero)arylpyrimidines has been investigated. The aryl substituted pyrimidines are readily obtainable from [3-(dimethylamino)-2-aryl allylidene] dimethylammonium perchlorates whilst the heteroaryl substituted pyrimidines are …

Heterocycles in peptide chemistry
The synthesis of 5-membered heterocyclic rings that bear both amine and carboxylic acid functional groups has been investigated using a 1,3-dipolar cycloaddition reaction strategy. These molecules, on incorporation into a chain of amino acids, have the potential to restrict the conformational …

Superelectrophiles and their chemistry
This thesis details the research conducted on the synthesis and reactivity of superelectrophilic di- and polycation salts based on 2-DMAP I. The reaction of 2-DMAP I and 1,3-diiodopropane II proceeded unexpectedly to give products III-V, thought to occur via a dicationic intermediate. Investigation …
