Molecular Structure of Trisilylmethane and Synthesis of 1,1,1-Trisilylethane

As a precursor for trisilylmethane, tris(triphenylsilyl)methane is prepared by a Merker-Scott reaction of chlorophenylsilane, bromoform, and magnesium turnings in boiling tetrahydrofuran.Chlorophenylsilane is formed in a new synthesis starting from phenylsilane and hydrogen chloride/AlCl3 in diethyl ether.The gas phase structure of trisilylmethane (H3Si)3CH, obtained from (PhSiH2)3CH via (BrSiH2)3CH, has been determined by electron diffraction.Data refinement confirmed a model of C3 molecular symmetry, with local C3v symmetry for the silyl group. - As a precursor for 1,1,1-trisilylethane, 1,1,1-tris(phenylsilyl)ethane has been prepared similarly from chlorophenylsilane, 1,1,1-trichloroethane and magnesium and converted via 1,1,1-tris(bromosilyl)ethane into CH3C(SiH3)3.
