Outline of Final Research Achievements

Single-walled carbon nanotubes (SWNTs) were demonstrated to render simple nickel catalysts effective in water. Integration of the nickel ions with chiral ligands and surfactants at the nanotube surface produces a highly enantioselective catalyst for nitrone formation from aldoximes and unsaturated ketones with long-term stability. Spectroscopy suggested that SWNTs enhanced electron density at the nickel center as well as provided a hydrophobic milieu.
