Synthese, Kernresonanz- und Schwingungsspektren der Hexamethyltrisilane X2MeSiSiMe2SiMe3, X = H, F, Cl, Br, I, Ph, OMe, OSO2CF3
摘要:
The syntheses, IR, Raman and Si-29 spectra of the title compounds are reported. Normal coordinate analyses have been carried out, and the calculated SiSi-force constants are compared with SiSi-coupling constants. They both increase with increasing electronegativity of the substituent X.
