This contribution describes a convenient synthetic method to obtain tris(trimethoxysilyl)silanides and demonstrates their efficiency as new building blocks in silicon chemistry. The reactions with different types of electrophiles result in novel polysilanes with high yields, enabling the synthesis of new precursors for silicon deposition.
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.
