Tóm tắt
Although carbonylnitrenes have been well studied by product analysis, very few direct spectroscopic observations of these reactive intermediates have been made. This thesis focuses on the direct observation and photochemical reactivity of carbonylnitrenes. Aroyl azides are studied as photochemical precursors to aroylnitrenes. Due to instability and low UV-Vis absorption of alkylcarbonyl azides, alternative photochemical precursors to alkylcarbonylnitrenes have been developed. The chemistry of carbonylnitrenes has been studied both by product analysis performed with and without trapping reagents (alkene, oxygen, and H-atom donors) and by nanosecond time-resolved infrared spectroscopy. In addition, we have also investigated the photochemical reactivity of thiocarbonylnitrene, the sulfur analogues of carbonylnitrene. Computational studies regarding the chemistry and spectroscopy of carbonylnitrenes are also discussed.
