The reaction of various secondary nitro compounds with 1.1 equivalents of potassium hydride in 1,4-dioxane and then with 0.10 equivalent of chlorotrimethylsilane gave the corresponding ketones in 62-90% yields. By a similar strategy, poly(1,3-diketones) were synthesized directly from nitroalkenes with sodium ethoxide, potassium hydride, and chlorotrimethylsilane in 1,4-dioxane. The use of chlorotrimethylsilane
各种仲硝基化合物与 1.1 当量的氢化钾在 1,4-二恶烷中反应,然后与 0.10 当量的三甲基氯硅烷反应,得到相应的酮,产率为 62-90%。通过类似的策略,聚 (1,3-二酮) 直接由硝基烯烃与乙醇钠、氢化钾和三甲基氯硅烷在 1,4-二恶烷中合成。使用催化量的三甲基氯硅烷是这一转化成功的关键;使用过量的三甲基氯硅烷会导致相同反应的收率很低。
