We report here the attempted synthesis of a stable 1-fluoro-2-hydrosilene bearing a Bpq group, which is a bulky aryl group bearing a cavity-shaped framework. We have successfully synthesized an overcrowded benzyldifluorosilane as a precursor. Treatment of the benzyldifluorosilane with 2 equiv of t-BuOK in THF afforded the corresponding benzyl anion, the structure of which showed a unique feature as a fluorosilene–KF complex.
我们在这里报告了一种带有 Bpq 基团的稳定 1-
氟-2-氢
硅烯的尝试合成,该基团是带有空腔状框架的大芳基。我们成功合成了一种过度拥挤的苄基二
氟硅烷作为前体。在 THF 中用 2 当量的 t-BuOK 处理苄基二
氟硅烷,得到相应的苄基阴离子,其结构显示出
氟硅烷-KF 络合物的独特特征。
