The Meerwein-Ponndorf-Verley (MPV) reduction of three model compounds benzaldehyde, acetophenone, and (S)-CMK, a pharmaceutical intermediate, were shown to be enhanced through the use of an improved catalyst, Al(OtBu) 3. The conventional catalyst, Al(OiPr)3 is effective at reducing aldehydes and ketones to their respective alcohols but the tetrameric aggregation state of the catalyst limits the rate of reductions as compared to the dimeric state of Al(OtBu)3. Because of the increased rate of reduction with Al(OtBu)3 in both neat iPrOH as well as mixed toluene:iPrOH systems, lower catalyst loading was achievable. The first successful MPV reduction in continuous flow was demonstrated on benzaldehyde. The reduction of benzaldehyde was optimized to continuously run at full conversion in only 11 minutes with less half of the conventional catalyst loading.

520 $a A new CO2 capture system was investigated using non-aqeuous amines, as opposed to conventional aqueous amine solvents, to reduce the amount of energy required for capture. This is extremely important as CO2 emissions continue to increase. Trialkylsilylamines were reacted with CO 2 to form ionic liquids that are thermally reversible. It was found that small structural modifications around the silicon atom, the amine reactive site, and along the backbone linking the two, greatly altered the physical and thermodynamic properties of the formed ionic liquids. CO2 capture capacities higher than predicted were achieved through a dual capture mechanism (chemical and physical absorption) as well as through incomplete equilibrium to form carbamic acids. Synthesis of a library of trialkylsilylamines was achieved, lending valuable information towards the optimization of improved CO2 capture solvents that meet the requirements of high capacity and low energy.
