摘要

采用低温紫外/可见光谱法、电子顺磁共振光谱法和量子化学方法测定了辐照冷冻1,3-二氧化丁二烯/CF3CCl3溶液中稳定的自由基阳离子的性质。结果表明，在光的作用下，两个氧环环裂解产物的环自由基阳离子都发生了C-C键的断裂，并进一步消除了甲醛分子，形成了双离子•CH2OC+CH2自由基阳离子。

Phototransformations of 1,3-Butadiene Diepoxide Radical Cations in CF3CCl3 at 77 K

The nature of radical cations stabilized in irradiated frozen 1,3-butadiene diepoxide/CF₃CCl₃ solutions was determined via low-temperature UV/Vis spectroscopy, electron paramagnetic resonance spectroscopy, and quantum chemistry. It was found that the cyclic radical cations yielded as radiolysis products undergo C–C bond cleavage in both oxirane cycles under the action of light with further elimination of molecular formaldehyde resulting in distonic ^•CH₂OC⁺CH₂ radical cations.
