Pyramlyl palladium(Il) complexes as phenylacetylene oligomerization and polymerization catalysts'
SegaPelo, T (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 ... -
Substituted nick el pyrazole and palladiumpyruzolyl complexes as catalyst precursors for ethylene polymeization
Nelana, S (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 ... -
Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
Moutloali, R.M (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 ...
