The mixed heteroadamantanes SiGe and SiSn are readily accessible from MeECl/SiCl/cat. Cl (4 × EMe, 2 × SiCl, 4 × Si-SiCl vertices; E = Ge, Sn). Different from SiGe, two skeletal isomers are formed in the case of SiSn. Site-selective SiCl-methylation of SiGe was achieved, leaving the SiCl groups untouched.
混合异金刚烷 SiGe 和 SiSn 可通过 MeECl/SiCl/cat.Cl（4×EMe，2×SiCl，4×Si-SiCl 顶点；E=Ge，Sn）轻易获得。与 SiGe 不同，SiSn 形成了两种骨架异构体。实现了 SiGe 的选择性 SiCl-甲基化，而 SiCl 基团则保持不变。
