Heterocycle carbonyl pyrazolyl palladium(II) complexes :synthesis, ethylene oligomerisation and polymerisation catalysis Ojwach, Stephen Otieno (University of the Western Cape, 2004)Reactions of furan, thiophene and alkyl carbonyl chlorides with Unsubstituted and substituted pyrazoles produced the desired pyrazolyl ligands, [R2pyrazole-CO-R/] (R= H, Me, tBu, Ph, R/ = furan, thiophene, Me or tBu) in ...
Pyrazole and pyrazolyl palladium(II) and platinum(II) complexes: synthesis and in vitro evaluation as anticancer agents Keter, Frankline Kiplangat (University of the Western Cape, 2004)The use of metallo-pharmaceuticals, such as the platinum drugs, for cancer treatment illustrates the utility of metal complexes as therapeutic agents. Platinum group metal complexes therefore offer potential as anti-tumour ...
Pyridine carboxamide and pyrazole palladium(II) complexes as catalyst precursors for phenylacetylene polymerization Shumbula, Poslet Morgan (University of the Western Cape, 2005)The objectives of this project were to synthesize and characterise pyridine carboxamide ligands and their palladium complexes and investigate their catalytic activity in the polymerization process of phenylactylene.
