Computational, structural and electrochemical properties of metal (III) tris-betadiketonato complexes
(University of the Free State, 2012)
English: A series of MnIII(β-diketonato)3 complexes (β-diketonato = acac, ba, dbm, tfaa, tfth, tffu, tfba and hfac) were synthesized and characterized with the aid of mass spectroscopy, elemental analysis, X-ray diffraction ...
Diolefin complexes of transition metals as 'venus fly-trap' templates
(University of the Free State, 2011-06)
English: The aim of this study was to gain a further insight into the bonding modes of 1,5-cyclooctadiene to various middle to late transition metal centres. The intension was to design a theoretical model of the influences ...
Chemical kinetics, electrochemistry and structural aspects of ferrocene-containing b-diketonato complexes of rhodium(I) and iridium(I)
(University of the Free State, 1999)
English: Synthetic routes to prepare new Rh(I)-β-diketonate complexes [Rh(FcCOCHCOR)(CO)2] and [Rh(FcCOCHCOR)(CO)(PPh3)] with Fc = ferrocenyl and R = Fc, C6H5, CH3 and CF3 have been developed and optimized. Optimized ...
A crystallographic and mechanistic investigation of manganese(i) tricarbonyl complexes
(University of the Free State, 2013-11)
Manganese has largely been used as a catalyst in epoxidation of olefins and the selective oxidation of unactivated C-H bonds in alkanes. Another major use of manganese is in water oxidizing catalysis, where manganese ...
O,O'-chelated titanium(IV) complexes: a synthetic, kinetic, electrochemical and structural study
