The remarkable wavelengh-dependent photoreactions of 3-methyl-2-(1-naphthyl)-2H-azirine (1) were observed in matrices at 10 K and in solutions at room temperature. Irradiation of 1 with the long-wavelength light (366 nm) exclusively gave the products formed by the cleavage of the C–N bond of the 2H-azirine ring, while the products derived from the C–C bond cleavage were predominantly obtained in the irradiation with the short-wavelength irradiation (>300 nm).
在10 K的基质中和室温下的溶液中,观察到了3-甲基-2-(1-
萘基)-2H-氮杂环
丙烯(1)显著的波长依赖性光反应。用长波长光(366 nm)照射1时,唯一得到的产品是通过2H-氮杂环
丙烯环的C–N键断裂形成的产物,而主要通过C–C键断裂得到的产物则在使用短波长照射(>300 nm)时获得。
