Abstract:

Compounds containing a tetradecachlorocyclohexasilane dianion are prepared by contacting trichlorosilane with a reagent composition comprising a tertiary polyamine. The compound �pedeta. SiH. sub. 2 Cl. sup. +1 !. sub. 2 �Si. sub. 6 Cl. sub. 14. sup. -2 ! wherein pedeta is N,N,N',N",N"-pentaethyldiethylenetriamine is prepared by contacting trichlorosilane with pedeta. The compound �Ph. sub. 4 P. sup. +1 !. sub. 2 �Si. sub. 6 Cl. sub. 14. sup. -2 ! is prepared by contacting trichlorosilane with a mixture of N,N,N',N'-tetraethylethylenediamine and triphenylphosphonium chloride. The tetradecachlorocyclohexasilane dianion can be chemically reduced to cyclohexasilane, a compound useful in the deposition of amorphous silicon films. The tetradecachlorcyclohexasilane dianion can also be contacted with a Grignard reagent to form a dodecaorganocyclohexasilane.
