Abstract
The invention relates to a method for producing formoxysilane. A silane of the formula R SiH , wherein R is an organic or inorganic substituent and n=0, 1, 2 or 3, is converted with carbon dioxide in a solvent in the presence of a catalyst consisting of a compound of a transitional metal pertaining to the subgroup VIIIb of the periodic system. The aim of the invention is to find a catalyst for the method mentioned above. The catalyst should be more simple, easy to produce and thus more cost-effective, easily available in large quantities and being provided with high activity and product selectivity. To this end, a halide of the transitional metal or a compound of the transitional metal are used as catalyst. Said compound is produced by converting a halide of the transitional metal with a nitrile in the presence of the silane of the formula R SiH .
