Exploring hetero-atom derivatization in maltols and flavonols : the effect on reactivity of flavonol dioxygenation.
… the evolution of CO; this reaction is called dioxygenation reaction. Model QDOs have been studied to probe flavonol dioxygenation, though of note, all the reported model QDOs are bidentate to the flavonol. In this dissertation, we probe the question of dioxygenation mechanism by …

Metal-free syn-dihydroxylation of alkenes using malonoyl peroxides
… metal-free methods for achieving syn-1,2- dioxygenation of alkenes. The use of hypervalent iodine, selenium, sulfur and peroxide reagents are discussed in terms of the advantages and limitations of each method. Chapter 2 details a mechanistic investigation into the dihydroxylation reaction …

Imidazolidinones in amine catalysis
… into the malonoyl peroxide mediated alkene dioxygenation reaction is made. DFT calculations and a mechanistic probe substrate are used to define the nature of the interaction between the peroxide and alkene. Chapter 9 summarises the work contained within Chapters 2-8 and suggests some …

Bio-inspired iron complexes featuring secondary coordination sphere interactions: Ligand design strategies and dioxygen reactivity
… to facial geometry of the ligand. Binding and dioxygenation of ortho-phenylene moieties is also described, mimicking the reactivity of ring-cleaving dioxygenase enzymes. Systematic modification of the related tripodal ligand was then carried out to examine the influence changes in the primary …
