Abstract (en)
[origin: WO2021197598A1] The invention relates to a one-pot method for producing oxido(tetraalkoxido)tungsten compounds in accordance with the general formula [W(O)(OR)4] (I), proceeding from WCl6, hexamethyldisiloxane, an alcohol ROH and an amine or NH3 gas. The invention further relates to the use of a compound [W(O)(OR)4] (I) and to a substrate, which on one surface has a tungsten layer or a layer containing tungsten, which are suitable for producing photovoltaic elements, semiconductor elements or vehicle exhaust gas catalysts. The method permits the production of defined products in a simple, cost-effective and reproducible manner with high purity and good to very good yields.
