The Challenge of Selectivity in Ethylene Oligomerization: Ligand Design and Metal Valence States
Catalytic ethylene oligomerization is a well understood industrially viable process. The large majority of scientific literature and patents concerning this process has been developed with the use of chromium catalysts. Commercial systems producing selective tri/tetramerization, non-selective …

Thermal decomposition studies on metallacycloalkanes and their precursors
… These transformations include olefin metathesis, ethylene oligomerization etc. The studying of thermal decomposition behavior of these compounds can help us to understand the termination step in the mechanism of these transformations. This thesis describes the thermal decomposition studies on some …

Olefin oligomerization reactions theoretical studies using cyclometallated palladium(II) catalysts and experimental studies on platinum(II) analogues
Ethylene oligomerization reactions catalysed by cyclometallated palladium(II) N-benzylidenebenzylamine complexes were studied theoretically. Density functional theory (DFT) calculations are reported on the interaction of various MAO models with the methylated pre-catalyst. The neutral MAO …

Divalent transition metal centers: the synthesis of new chemical vapor deposition precursors and studies of ethylene polymerization and oligomerization catalysts
… The reactivity of these complexes with ethylene when activated with an aluminum alkyl co-catalyst will be of primary focus. The N,N-dimethylaminodiboranate compounds Ti(DMADB)2, Cr(DMADB)2, and Cp*Cr(DMADB) are active ethylene polymerization catalysts in the presence of an aluminum …
