Towards polyethylene-based materials with non-alternatively incorporated carbon monoxide monomer
… with 1,5-cyclooctadiene followed by olefin hydrogenation were also pursued. Five new κ2-[phosphine-(di)phenolate]Ni(II)Me complexes with either mono- or trinuclear structures were also synthesized, characterized, and utilized in the catalytic (co)polymerization of ethylene. These …

Iridium complexes as highly active catalysts for hydrogen isotope exchange and hydrogen borrowing processes
… catalysts for hydrogen isotope exchange and olefin hydrogenation processes. The work described within this thesis centres upon the expansion of these catalysts' reactivity in hydrogen isotope exchange, as well as the synthesis and application of a series of novel iridium complexes, designed …

Surface Characteristics of Silica Polyamine Composites
… on SPC materials were investigated for olefin hydrogenation activity. Hydrogenation of monoenes and dienes was investigated and found comparable to currently used catalysts in some cases. The most potentially useful result of this catalysis work was the selective hydrogenation of a …

Boron in the primary and secondary coordination spheres of iron and nickel
… This species is a slow but competent olefin hydrogenation catalyst. In an effort to access a more reactive precatalyst, the iron chemistry of the bis(phosphine)borate ligands [Ph2 BPPh] and [Ph2 BPfBu] ([Ph2BP] = Ph2B(CH2 PR2)3, R = Ph and tBu) was explored. Iron(II) halide, aryloxide, …

Investigation of the promotional effect of Cu and Ag on iron-based Fischer-Tropsch catalysts using ferrites as model catalysts
… Fe3O4. It is further shown that the olefin selectivity in the Fischer-Tropsch synthesis over the catalyst AgFeO2 (ex) is higher than that obtained over the catalyst CuFe2O4 (ex) and CuFeO2 (ex), which can be ascribed to a lower hydrogenation activity of silver in comparison to copper …

The catalytic hydrogenation of carbon-carbon and carbon-nitrogen multiple bonds by a cobalt(I) complex
… transition metal complexes for the catalytic hydrogenation of carbon-carbon multiple bonds can be attributed to the well-defined reactivity, stability and overall high activity of such catalytic systems. The development of sustainable, more abundant and relatively less toxic late first-row …
