An investigation into the synthesis, characterisation and some applications of novel metal-containing polymers and dendrimers of transition metals
(University of the Western Cape, 2003)
metal-containing complexes, that exhibit enhanced chemical and physical properties. This thesis describes the synthesis of new metal-containing linear polymers and dendritic molecules.
Chapter 1 presents an overview of ...
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 ...
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 ...
Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
(University of the Western Cape, 2003)
Thermal analysis data of compounds A, C, F and I established that they were nonmesogenic
while E and G were found to be mesogenic. The lack of mesogenic behaviour
of A could be attributed to hydrogen bonding. The ...
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 { ...
