A DFT study of the catalytic hydrocyanation of ethylene with nickel complexes
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: DFT calculations employing the B3LYP functional were done to investigate the mechanism for the Ni-catalyzed hydrocyanation of ethylene as proposed by Tolman. Although this reaction is an important industrial ...
Gold complexes obtained from gold ylide preparations
(Stellenbosch : Stellenbosch University, 2005-04)
ENGLISH ABSTRACT: This investigation comprised the synthesis and characterisation of new Au(I) phosphonium ylide complexes and other compounds formed during coordination reactions. These complexes could exploit the ...
An investigation into the complex formation and potential solvent extraction of Os(IV/III) with N, N - dialkyl - N′- acyl(aroyl)thioureas
(Stellenbosch : University of Stellenbosch, 2006-03)
This study involved the preliminary investigation into the potential liquid-liquid extraction of Os(IV/III) from hydrochloric acid solutions with ligands of type N,N-dialkyl-N′-acyl(aroyl)thioureas (HL), and ultimate ...

The synthesis, stability and structures of two novel macrocyclic ligands and their complexes
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: This study comprises the synthesis and full characterization of two novel pendant-arm donor macrocyclic ligands. The stability and structure of the complexes of these two ligands with a series of metals ...
Chemical speciation of RhIII complexes in acidic, halide-rich media by means of 103Rh NMR spectroscopy : the importance of speciation in the selective separation and recovery of rhodium
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: In this thesis, the recovery of RhIII from both synthetically prepared and authentic industrial PGM-containing solutions was systematically investigated via organic precipitation methods using several ...
