| Research Abstract |
This research projects mainly focused on the development of new photochemical oxidation processes in a cryogenic oxygen matrix. The following research results have been obtained.
1. Charge-transfer photooxygenation of sulfides in a cryogenic oxygen matrix: IR spectroscopic observation of persulfoxides.
2. Reaction of dimesitylsilylene in a cryogenic oxygen matrix: IR spectroscopic observation of a silylene-oxygen adduct.
3. Photolysis of azides in a cryogenic oxygen matrix: formation of isocyanate from a ketenimine dioxetane intermediate.
4. Spectroscopic studies on charge-transfer photooxygenation of disiliranes: open structure of a peroxide intermediate
