exist in their enol forms. Photolysis of these dinitro ketones in ethanol gave diosphenols arising from the removal of their two nitro groups. On the basis of the results of the irradiation of hypothesized intermediate obtained by synthesis, we suggest the path likely to lead to the removal of the nitro groups.
2,4-Dinitro-5α- 和 5β-cholestan-3-ones 是由母体 3-ones 用改进的标准方法二硝化制备的。光谱表明,在
乙醇中,这些 α,α'-二硝基酮以其烯醇形式存在。这些二硝基酮在
乙醇中的光解产生二
酚,这是由于去除了它们的两个硝基而产生的。根据合成获得的假设中间体的辐照结果,我们提出了可能导致硝基去除的路径。
