Chlorinated and brominated aryltrisilanes ClnSi3Ar8-n and BrnSi3Ar8-n (Ar = phenyl, p-tolyl) as well as tetrasilanes (Ar = phenyl) have been synthesized. In a first step, Ph3SiSiPh2SiPh3, Ph3SiSiClPhSiPh3, p-Tol3SiSiPh2SiPh3, Ph3SiSip-Tol2SiPh3, Cl3SiSiCl2SiPh3 or H(SiPh2)4H have been prepared, and subsequently treated with trifluoromethanesulfonic acid (CF3SO3H), followed by a nucleophilic substitution of the triflate substituent (CF3O2SO) with X- (X = Cl, Br, H). The physical properties of the resulting compounds, which are valuable precursors for the synthesis of aryltrisilanes HnSi3Ar8-n and aryltetrasilanes HnSi4Ar10-n, have been described and their IR and 29Si NMR spectra have been reported.
