Chlor-, Brom- und Iodtrisilane: Synthesen und 29Si-Kernresonanzspektren
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.
Aryltrisilane Si3ArnH8−n (Ar = Ph, p-Tol; n = 2–7)
摘要:
Aryltrisilanes with the general formula ArnSi3H8-n (Ar=phenyl and/or p-tolyl, n = 2,3,4,5,6,7) have been prepared from corresponding arylfluoro-, arylchloro- or arylbromotrisilanes and LiAlH4. The infrared spectra as well as Si-29 NMR spectra are reported and the properties of the aryltrisilanes are described. (C) 1997 Elsevier Science S.A.
