Thermal decompostion of 1-methyl-1,2,3-benzotriazian-4(1H)-one (1) above 120°C gave rise to 1-methylbenzazetinone (2), which was trapped in solid argon at 15 K; near-UV irradiation of (2) converted it partially into its iminoketene isomer (3), and the reverse conversion of (3) into (2) was effected with longer wavelength irradiation.
1-甲基-1,2,3-苯并三氮杂-4(1 H)-一(1)在120℃以上热分解产生1-甲基苯并ze丁酮(2),将其在15 K下俘获于固体氩气中;(2)的近紫外线照射将其部分转化为其亚氨基烯酮异构体(3),并且在较长波长的照射下将(3)反向转化为(2)。
