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.
