  Photochemical Reactions of Nitroso Oxides at Low Temperatures:  The First Experimental Evidence for Dioxaziridines

  摘要：

  Several singlet nitroso oxides (3a-e) were generated by the thermal reaction of triplet nitrenes (2a-e) with triplet oxygen at. 95 K in 2-methyltetrahydrofuran. After photolysis of the nitroso oxides at 77 K using strong light intensities, the formation of intermediates was observed for the first rime. From spectroscopic, kinetic, and chemical arguments, we postulate the formation of the following dioxaziridines: 4-(dioxaziridin-yl)stilbene (4a), 4-(dioxaziridin-yl)-4'-nitrostilbene (4b), 4'-(dioxaziridin-yl)-4-(dimethylamino)st (4c), 4'-(dioxaziridin-yl)-4-aminobiphenyl (4d), and 4-(dioxaziridin-yl)-4'-(nitrene-substituted)stilbene (4f). All dioxaziridines observed are highly reactive species. At 77 K, they react thermally to form the corresponding nitro compounds (5). The velocity of the ring opening reaction of the dioxaziridines (4 --> 5) is not significantly influenced by substituents; the rate constants at 77 K are all equal to 0.0030 +/- 0.0005 s(-1). The transients were characterized by stationary UV/vis and/or ESR spectroscopy. Ab initio calculations of the thermal reaction of the nonsubstituted dioxaziridine (6) and N-phenyldioxaziridine (9) were performed. From this, it follows that dioxaziridines are experimentally observable species which are separated from the corresponding nitro products by an orbital symmetry-forbidden barrier.

  We synthesized hetero-Diels–Alder cycloadducts from acyl nitroso derivatives and 9,10-dimethylanthracene, to be photo-inducible HNO-releasing agents and found that introduction of conjugated nitroaromatic groups effectively enhanced the responsiveness of HNO release to UV-A irradiation; we confirmed photoinduced HNO formation by EPR and GCMS analysis.
