Abstract

In this contribution, a convenient synthetic method to obtain tris(trimethoxysilyl)silanides (M=Li, Na, K, Cu) 5 a–d is described. 5 a–d are easily accessible deriving from dodecamethoxyneopantasilane 4 in excellent yields and could be fully characterized via NMR spectroscopy and X-ray crystallography. The efficiency of 5 a–d to serve as a new building block in silicon chemistry is demonstrated by the reactions with two different types of electrophiles (carbon- and silicon-electrophiles). In all cases the salt metathesis reaction gave rise to novel polysilanes in excellent yields. The possibility of a post-functionalization to perhydropolysilanes as well as perchloropolysilanes enables the synthesis of new precursors for silicon deposition.
