Abstract

The mixed heteroadamantanes Si₆Ge₄ and Si₆Sn₄ are readily accessible from Me₂ECl₂/Si₂Cl₆/cat. Cl^- (4 × EMe₂, 2 × SiCl₂, 4 × Si-SiCl₃ vertices; E = Ge, Sn). Different from Si₆Ge₄, two skeletal isomers are formed in the case of Si₆Sn₄. Site-selective SiCl₃-methylation of Si₆Ge₄ was achieved, leaving the SiCl₂ groups untouched.
