Synthesis, characterisation and reactions of ferrocene anchored bis(phosphino) palladium (II) and platinum (II) aryldichalcogenide complexes
(University of the Western Cape, 2000)
Reactions of M(dppf)Cl2 (M : Pd, Pt) and Pd(dippf)Cl2 with equimolar amounts of the aryldichalcogen reagents, 1,2-benzenedithiol (1,2-(HS)C6H4(SH) (a)), 3,4-toluenedithiol ((HS)C6H3Me(SH)) (b), 3,6-dichloro 1,2-benzenedithiol ...
Pyramlyl palladium(Il) complexes as phenylacetylene oligomerization and polymerization catalysts'
(University of the Western Cape, 2004)
PyrazoM compounds have been extensively used to prepare metal complexes, but it
is only recently that they have been investigated as catalysts for the polymerization of
unsaturated hydrocarbons. In catalyzn11g the ...
The synthesis of analogues of the Anti-TB (agent: Diospyrin)
(University of the Western Cape, 2005)
Diospyrin, a bisnaphthyl quinone molecule with proven anti-TB activity can be retrosynthetically formulated into two halves. In this work, the analogue chosen to be synthesized was similarly retrosynthesized into two halves. ...
Substituted nick el pyrazole and palladiumpyruzolyl complexes as catalyst precursors for ethylene polymeization
(University of the Western Cape, 2003)
This study concerns the synthesis of pyrazole and substituted pyrazole nickel
complexes of the type [(3,5-R,R',pz)2NiB rz ( Pz : pyrazole; R = R' = cHr (1), tBu
(a)l and of the type [(3,5-R,R'pz)aNiBrz R: H, R' : CHr ...
Hydrothermal synthesis and optimisation of zeolite Na-Pl from South African coal fly ash
(University of Western Cape, 2009)
Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for
energy. Management of this fly ash has been a concern and various approaches for its beneficial
use have been investigated. ...
The synthesis of methoxy-2-hydroxy-1,4- naphthoquinones and their reaction with aliphatic aldehydes under basic conditions.
(University of the Western Cape, 2003)
Although literature reports on the synthesis of variously substituted 2-hydroxy-1 ,4-
naphthoquinones appeared to be reasonable; in our hands difficulty was experienced
in duplicating much of the work.
In order to address ...
Pyrazolyl palladium complexes with heterocyclic carbonyl linkers as catalyst precursors for ethylene and phenylacetylene polymerization.
(University of the Western Cape, 2003)
The pyrazolyl ligands 2,6-bis(3,5-r2p*azolylcarbonyl)pyridine {r : 'bu (l1), me (l2)),2,6-bis(3-methylpyrazolylcarbonyl)pyridine(l3)'2'6- bis(pyrazolylcarbonyl)pyridine (l4) and 2,5-bis(3,5-rzpyrazolylcarbonyl)thiophene { ...
Titanium compounds and plant growth
(University of the Western Cape, 2001)
The effect of titanium compounds on the growth of tomato plants, Lycopersicum
esculentum (cultivar Floridade), was studied under greenhouse conditions.
Aqueous suspensions (TiO2) and solutions (complexes of titanium (IV) ...
The oxidation of the lower primary alcohols ln a catalytic membrane reactor
(University of the Western Cape, 2000)
Methanol and ethanol are important chemical feedstock used in industrial chemistry, since they are the starting materials for the synthesis of various products, including hydrocarbons and mild oxidation products. For ...
ISOLATION AND CHARACTERIZATION OF ANTIMICROBIAL COMPOUNDS FROM GALENIA AFRICANA
(University of the Western Cape, 2001)
Galenia africona, commonly known as "kraalbos" or "geelbos" belonging to the family Aizoaceae, is a dominant plant throughout the Namaqualand area. It is an active invader and is especially abundant in disturbed areas ...
