Process for the preparation of higher hydridosilanes of the general formula H- (SiH 2 ) n -H where n ≥ 2, in which - One or more lower hydridosilanes - hydrogen and one or more transition metal compounds comprising elements of VIII. Subgroup of the Periodic Table and lanthanides, at a pressure of more than 5 bar absolute brings to the reaction, then relaxed and separated from the resulting reaction mixture, the higher hydridosilanes. |
