Abstract:	The reactions of 1:1 mixtures of the trisilylmethane HC(SiMe₂Cl)₃ (1b) and organo Group 14 trichlorides (RMCl₃, R=Me, Ph, vinyl (Vi); M=Si, Ge, Sn) with Li₂E (E=S, Se) in THF yielded the new bicyclo[2.2.2]octanes HC(SiMe₂E)₃MR (2a-6b). The products were identified by GC-MS and multinuclear NMR spectroscopy. Trends of the NMR data are discussed. The molecular structures of HC(SiMe₂S)₃SiMe (2a), HC(SiMe₂S)₃SiPh (3a), HC(SiMe₂Se)₃SiVi (4b) and HC(SiMe₂Se)₃GeMe (5b) are reported.
