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.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、近年水中で展開されてきた有機化学に新たな領域を切り拓くと同時に、カーボンナノチューブの新たな活用法を提示するものである。また反応媒体として水を活用することで、均一系触媒や有機溶媒中では達成できない精密な触媒的不斉合成発展へ繋がることが期待される。
