Developments in the hydrogenation of challenging substrates utilising transition metal complexes
(University of St Andrews, 2015) - Thesis,
This thesis describes the developments of new protocols for the hydrogenation of challenging substrates. Three specific substrates were highlighted for study after an initial review of the literature; benzofurans, esters ...
Carbon monoxide hydrogenation using ruthenium catalysts
(University of St Andrews, 2012-11-30) - Thesis,
Rh catalysed hydrogenation of enamines : factors affecting the rate and enantioselectivity
(University of St Andrews, 2017) - Thesis,
Polymer precursors from catalytic reactions of natural oils
(University of St Andrews, 2013-06-26) - Thesis,
The bidentate ligand 1,2-bis(ditertbutylphosphinomethyl)benzene has been shown to be a very efficient catalyst for operating the alkoxycarbonylation of alkenes and unsaturated esters and carboxylic acids giving a very ...
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 ...
Surface chemistry of 2-butanol and furfural on Cu, Au and Cu/Au single crystals
(University of St Andrews, 2016) - Thesis,
In this study, the adsorption of 2-butanol and furfural was investigated on Au (111), Cu (111) and Cu/Au (111) surfaces. It was hoped that by studying how these species adsorbed on these surfaces , insight would be provided ...
Enantioselective hydrogenation using ruthenium complexes of tridentate ligands
(University of St Andrews, 2011-06-22) - Thesis,
This thesis describes the development of the [RuCl₂(P^N^N)L] catalytic system for asymmetric hydrogenation. It has been demonstrated that the current system is efficient in preparing a range of bulky chiral alcohols in ...
Solid phase strategies for the preparation of phosphorus ligand libraries
(University of St Andrews, 2014-06-25) - Thesis,
Catalysis plays a key role in chemical conversions by making them faster and more selective. Despite its widespread use and decades of academic and industrial research, limited catalyst selectivity and stability still call ...
Novel chiral wide bite angle ligands for asymmetric catalysis
(University of St Andrews, 2013-03-01) - Thesis,
Achiral wide bite angle ligands have been shown to be highly active and to induce excellent chemo- and regioselectivities in many homogeneously catalyzed reactions. However, only a few examples of chiral wide bite angle ...
A multi-diverse approach to catalysis : ruthenium, gold and FLP catalysis
(University of St Andrews, 2018-06-27) - Thesis,
Ruthenium-based homogenous catalysis is a broad and extremely useful branch of transition metal catalysis. Surely, the most famous example is olefin metathesis, for which Yves Chauvin, Robert Grubbs and Richard Schrock ...
