29Si-Kernresonanzspektren und synthese von bromdisilanen und ioddisilanen
摘要:
The syntheses of Bromodisilanes BretaSi2H6-eta and Iododisilanes IetaSi2H6-eta (eta = 1, 2, 3, 4, 5), starting from aryldisilanes AretaSi2H6-eta (Ar = phenyl, alpha-naphthyl, mesityl) are reported. The Si-29-NMR-spectra of all compounds, including (SiSi)-Si-29-Si-29-coupling constants, have been measured.
Bromdisilan: Verbesserte synthese, schwingungsspektren und normalkoordinatenanalyse
摘要:
Bromodisilane was prepared in high yields from 1-naphthyldisilane or mesityldisilane and gaseous HBr, avoiding the preparation and manipulation of disilane. The IR and Raman spectra of BrSi2H5 and BrSi2D5 were recorded and assigned with the aid of normal coordinate analysis.
