Abstract:

Both products, n-butyraldehyde and iso-butyraldehyde from propene hydroformylation are key building blocks for the synthesis of many chemical intermediates, and although high linear selectivity has been achieved, any form of branched selectivity remains very difficult to attain. This project aims to deliver a catalyst that can selectively produce branched iso-butyraldehyde as the major product from propene hydroformylation. One approach discussed is to study terphenyl phosphines as ligands. The synthesis of substituted terphenyls through Suzuki-Miyaura coupling reactions between aryl boronic a

Abstract:

Thesis advisor: James Morken<br>Asymmetric hydroformylation (AHF) is a metal-catalyzed reaction in which CO and H2 are added across an olefin to form a new carbon-carbon bond. AHF has perfect atom-economy and is an ideal way to form a chiral aldehyde. However, the utility of branch selective hydroformylation is limited due to a lack of readily available ligands and restrictions on a wide variety of terminal olefins. Herein, Rh-catalyzed asymmetric hydroformylation of 1-alkenes is reported using commercially available Ph-BPE ligand to generate α-chiral aldehydes. A wide range of terminal olefin

Abstract:

Aqueous-biphasic organometallic catalysis is, as illustrated by the industrial hydroformylation of propene and butene, one of the most promising ways to overcome the intrinsic problem of catalyst separation in organometallic catalysis. However, for poorly water-soluble substrates, mass transfer limitations bring the reaction rate below any that could be economically viable, greatly limiting the scope of this elegant technology. We have studied three different strategies to overcome this limitation. We developed additives that speed up the reaction whilst retaining fast phase separation and goo

Abstract:

The hydroformylation of 1-octene with supported ionic liquid phase catalyst was demonstrated when using a system involving the substrate, reacting gases and products in CO₂ and N₂ flow over a fixed bed supported ionic liquid phase catalyst (silica gel and carbon aerogels as solid support respectively) at different system pressures. Yields, reaction rates, selectivities and rhodium leaching were all monitored. A pressure of CO₂ flow just below the critical point of the flowing mixture (106 bar at 100 °C if no 1-octene has been converted) was the best condition for the hydroformylation. It gave

Hydroformylation of olefins (OXO synthesis), one of the oldest organometallic catalytic reactions, continues to be of interest because of its commercial significance. Great interest recently has been placed on the development of immobilized homogeneous catalysts that combine the virtues of conventional heterogeneous and homogeneous catalysts. The objective of this dissertation is to investigate novel phosphine modified water soluble cobalt and platinum complexes as homogeneous and immobilized hydroformylation catalysts.

Abstract:

The two-phase rhodium-tri(m-sulfonatophenyl)phosphine (Rh-TPPTS) system for the hydroformylation of 1-octene, 1-decene, and 1-dodecene to the corresponding aldehydes, has been investigated. Due to the two distinct phases - the catalytic species in the aqueous phase and the products and reactants in the organic phase - the separation of the catalyst was easily facilitated. A comparison was made of the activity, selectivity towards linear aldehydes, and catalyst lifetime of two systems where i) the active catalytic species were generated in situ from rhodium trichloride (RhCl₃.3H₂O) and excess p

The focus was on two mutants of SCP-2L (SCP-2L A100C and SCP-2L V83C) both of which possess a hydrophobic tunnel in which apolar substrates can accumulate. The crystal structure of SCP-2L A100C was determined and discussed with a special emphasis on its hydrophobic tunnel. The SCP-2L mutants were covalently modified at their unique cysteine with two different N-ligands (phenanthroline or dipicolylamine based) or three different phosphine ligands (all based on triphenylphosphine) in

Abstract:

Ph.D. (Chemistry)<br>Rhodium-catalyzed hydroformylation is one of the most important industrial processes for the production of linear and branch aldehydes. Aldehydes serve as intermediates in the production of various fine chemicals. Rh-based homogeneous catalysts for aldehydes production have demonstrated high yields and selectivity. Catalyst separation and recovery of expensive Rh-metal from reaction mixtures is a challenge to this process. With increasing industrial demand for highly selective processes, homogeneous catalysis could well be extensively employed if catalyst recovery from pro
