Photolysis of 1 in chloroform yielded 2 as the major product and a small quantity of 3. Laser flash photolysis demonstrated that upon irradiation, the first excited triplet state of the ketone (T1K) of 1 is formed and decayed to form radical 4, which has a λmax at 380 nm (t = 2 μs). Radical 4 expelled a nitrogen molecule to yield imine radical 5 (λmax at 300 nm). Density functional theory (DFT) calculations showed that the transition state barrier for the formation of 5 is approximately 4 kcal/mol. In comparison, photolysis of 1 in argon matrices resulted in triplet nitrene 6, which was further characterized with 15N and D isotope labeling and DFT calculations. Prolonged irradiation of 6 yields triplet imine nitrene 7.
