Outline of Final Research Achievements

The Grignard reaction is one of important reactions for organic synthesis. In this research project, we planned to generate a gas-phase "Grignard reagent" by co-expansion of the Mg atom and organic compounds, CH3I and diethylether(DEE), through a supersonic nozzle. Mixed clusters formed were ionized by a vacuum ultraviolet(VUV) laser and analyzed by a TOF mass spectrometer.
Various conditions were surveyed and long sequences of mixed clusters of CH3I and DEE, however no mixed clusters containing Mg atoms. One limitation of our experiment is the sensitivity for metal atoms. The absolute concentaration of the Mg atoms formed by the laser vaporization may be too low for the VUV-single photon ionization.
