Synthese von Phenylbrom-, Phenyliod- und Phenylwasserstoff-trisilanen
摘要:
The syntheses of phenylbromo- and phenyliodotrisilanes XnSi3Ph8-n (X = Br, I) are described. starting from 1.1.1.3.3.3-hexaphenyltrisilane, octaphenyltrisilane. 1-(p-Tolyl)heptaphenyltrisilane or 1.1.1-Tris(p-tolyl)pentaphenyltrisilane. A subsequent reduction with LiAlH4 gives the corresponding phenyltrisilanes HnSi3Ph8-n. All compounds were characterized with spectroscopic methods (Si-29-NMR, IR) and elemental analyses.
