Umsetzung von Lithiiertem 2-Hydroxybiphenyl Bzw. 2′-Hydroxy-Mterphenyl Mit Halogenverbindungen von Silicium und Germanium, Phosphor und Arsen

Abstract

The reaction of lithiated 2-hydroxybiphenyl and 2′-hydroxy-m-terphenyl resp. with SiCl₄ and SiBr₄ resp. yields the aryloxyhalogenosilanes 1-6 and the 1-oxa-10-silaphenanthrenederivative 7. PCl₃ and POCl₃ resp. react to yield the phosphanes 8-11 and the P(V)-derivative 12. With AsCl₃ the 1-oxa-10-arsaphenanthrene 13 was obtained. With the germaniumdichloride-dioxane complex and GeCl₄ resp. the spirocyclic germabiphenanthrene compounds 14 and 15 and the 1-oxa-10-germaphenanthrene 16 were formed. The compounds were characterized analytically and spectroscopically (n.m.r.: ¹H, ²⁹Si, ¹³C, ³¹P, and by mass spectroscopy).
