Utilisation of various bonding modes of nitrogen-rich heterocycles in gold(I) chemistry
(Stellenbosch : University of Stellenbosch, 2006-03)
This study describes the exploitation of numerous donor ligand possibilities presented by
selected nitrogen-rich heterocyclic ligands towards gold(I). The preparation and structural
characterisation of novel gold(I) ...
New ligands for gold : bonding mode and structural complex characterisation
(Stellenbosch : Stellenbosch University, 2008-12)
Novel gold(I) trithiophosphite complexes were synthesised by utilising the ligands P(SR)3 (R
= Me, Ph) and 1,2-bis(1,3,2-dithiaphospholan-2-ylthio)ethane (2L). Reaction with (tht)AuCl
or (tht)AuC6F5 readily yielded the ...
Inherently chiral calixarenes; methodology and applications
(Stellenbosch : Stellenbosch University, 2016-12)
ENGLISH ABSTRACT: The use of chiral directing groups has provided an efficient route to meta-functionalised inherently chiral
calixarenes. Previously reported ortholithiation methods, incorporating chiral oxazolines have ...
High resolution NMR studies concerning the solvation/hydration and coordination chemistry of Pt (II/IV) compounds
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: Pt(JV) complexes with S, 0-donating aroylthioureas have been synthesized by oxidative addition of
elemental halogens to the Pt(JJ) precursors, leading to the first-reported crystal structures of Pt(JV) ...
Inclusion Studies of Metal-Organic Hosts
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The primary objective of the work presented in this thesis was to prepare and investigate the properties of novel inclusion complexes of metal-organic host materials. Two types of host materials were ...
A multinuclear magnetic resonance spectroscopy study of E/Z configurational isomers of unsymmetrical N-alkyl-N-alkyl(aryl)-N'-acylthioureas of platinum(II) complexes
(Stellenbosch : Stellenbosch University, 2006-12)
ENGLISH ABSTRACT: The partial double bond character of the carbon-nitrogen bond of the (S)C-NRR’ moiety results in unsymmetrical
dialkyl-substituted N-alkyl-N-alkyl(aryl)-N’-acylthioureas, R”C(O)NHC(S)NRR’ (HL) displaying ...
Cation-π induced association and nano-structured aggregate formation of water-soluble [PtII(diimine)(Ln-S,O)]+ complexes examined with high-resolution 1H and DOSY NMR : towards understanding their potential antimalarial activity
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: Please refer to full text for abstract
Flexible Co(II) Metal-Organic Frameworks with Mixed Ligands under Controlled Pressure
(Stellenbosch : Stellenbosch University, 2019-12)
ENGLISH ABSTRACT: A number of flexible metal-organic frameworks (MOFs) are shown to undergo phase changes under CO2 gas pressure and, in two cases, the mechanisms of these changes have been elucidated using computational ...
Reversible photo-induced isomerization of cis-[M(L-κS,O)2] (M=PdII, PtII) complexes with N,N-dialkyl-N’-acyl(aroyl)thiourea ligands (HL): Key to the isolation of novel geometric trans-[M(L-κS,O)2] and trans-[M(L-κS,N)2] isomers
(Stellenbosch : Stellenbosch University, 2018-03)
ENGLISH ABSTRACT: The reaction of a series of selected N,N-dialkyl-N’-acyl(aroyl)thioureas to PtII or PdII formed exclusively cis-[M(Ln -κS,O)2] complexes which were fully characterized by melting point determination, 1H, ...
Ligand Design for the selective removal of metal Ions from industrial streams and wastewater
(Stellenbosch : Stellenbosch University, 2016-12)
ENGLISH ABSTRACT: This thesis reports the development of new types of solvent extractants for use in the hydrometallurgical recovery of base metals, and addresses the ligand design features which are needed to control the ...
