Brown, Orain, A

A series of phosphoranimide-supported first-row transition metal clusters were prepared, structurally characterized, and investigated for catalytic hydrogenolysis of carbon-heteroatom bonds. Homoleptic heterocubane clusters, as well as two-dimensional bi- and tetranuclear compounds of manganese,...

Salt metathesis between CoCl2 and [KNPEt3]n provides a new route to the halide-substituted cobalt phosphoranimide cluster [CoCl(NPEt3)]4. This cluster is a useful precursor for the preparation of alkyl-capped cobalt phosphoranimide complexes. The methylated heterocubane [CoMe(NPEt3)]4 was...

An investigation into the relatively new carbene class, N-heterocyclic olefins (NHOs) was completed. An improved synthesis of the ligand was developed. NHOs were tested as ligands for late transition metal complexes. Specifically complexes with rhodium, gold and palladium were synthesized and...

This dissertation reports a crosslinked catalyst organic framework, which was prepared by an alternating ring opening olefin metathesis polymerization (alt-ROMP) between dichloro{N,N'-bis({(2-diphenylphosphino)phenyl}methylidene)bicyclo[2.2.1]-hept-5-ene-2,3-diamine}-ruthenium,...

Organic chemistry has its foundations in the 19th century; since, it has grown into a number of industries affecting our daily lives such as the manufacture of goods and life saving pharmaceuticals. The need for new and increasingly efficient synthetic methods has grown in response to the...

Fortuitous characterization of the cationic nickel cluster [Ni4(NPtBu3)4][Li3Br4(Et2O)3] led to the rational syntheses and characterization of the mixed-valence low-coordinate cationic nickel cluster: [Ni4(NPtBu3)4]BPh4 and [Ni4(NPtBu3)4]PF6, and subsequently the preparation of the anionic...

Molecular transition metal catalysts offer unique potential for the production of fine chemicals. Chemical processes carried out in the presence of well defined molecular catalysts often only require mild, easily accessible conditions, fewer sacrificial reagents, and can selectively produce a...

Hass, Michael J.

A method was developed to immobilize and reuse a catalyst for the asymmetric cycloisomerization of enynes. Immobilization is achieved through use of metal containing monomers, which are reacted with a cycloolefin via an alternating ring-opening metathesis polymerization, assembling a...

In recent years, there has been considerable interest in gaining a fundamental understanding of nanoparticle (NP) synthesis and reactivity due to their wide applicability in the fields of biomedicine, optoelectronics and catalysis. Although metal NPs with a small and narrow size distribution tend...

The use of transition metal catalysts - either homogeneous (discrete well-defined metal complexes) or heterogeneous (more poorly-defined metal surfaces) - play an important role in the transformations of small substrates into larger, value-added compounds. Although heterogeneous catalysts have...
