In general, decamethylsilicocene (1) reacts with Brønsted acids under oxidative addition yielding SiIV compounds of the type (Me5C5)2Si(H)X (2)–(7); as an exception, the cyclotetrasilane (Me5C5SiF)4(8) is formed in the reaction with tetrafluoroboric acid and has been characterized by an X-ray diffraction study.
通常,十甲基硅茂金属(1)在氧化加成下与布朗斯台德酸反应,生成(Me 5 C 5)2 Si(H)X(2)–(7)类型的Si IV化合物;作为例外,在与四氟硼酸的反应中形成了环四硅烷(Me 5 C 5 SiF)4(8),并通过X射线衍射研究对其进行了表征。
Chemistry of decamethylsilicocene: Oxidative addition of compounds with XH bonds (X F, Cl, Br, O, S)
substrates HX, the corresponding oxidative addition products 2–9, 11, 12, and 15 of the type (σ-Me5C5)2Si(H)X are formed in good yields. Reactions of the hydrogen halides HF, HCl, and HBr with 1 lead to the silanes 2, 3 and 4, respectively. The oxo acids trifluoroacetic acid and propionic acid react with 1 to give the compounds 5 and 6, respectively. Phenol and p-methylphenol add to 1 to give the compounds
