摘要:
Halogenated trisilanes XnSi3H8-n with X = Cl, Br, I and n = 2-7 as well as the tetrasilanes H2XSiSiX2SiX2SiX2H have been prepared by dearylation of appropriate aryltrisilanes and aryltetrasilanes (aryl = phenyl, p-tolyl) with either liquid or gaseous hydrogen halides. The compounds have been characterized with elemental analysis as well as Si-29 NMR spectroscopy. (C) 1997 Elsevier Science S.A.
