Synthesis of methoxysilanes by the reaction of metallic silicon with methanol using copper(II) acetate as the catalyst

Study of the Effect of Zn, Sn, and Pb Additives on the Direct Mechanochemical Synthesis of Tetramethoxysilane in the Presence of CuCl and CuO Catalysts

“…His works launched a study of the direct synthesis of alkoxysilanes (DSAlk), especially trialkoxysilanes, which are the “green” analogs of trichlorosilane, in the production of high-purity crystalline silicon for microelectronics . Over the past few decades, there have been a large body of publications devoted to the direct synthesis of trialkoxysilanes using various catalysts such as a Cu 2 O/CuCl mixture, CuCl, − abraded material from the brass milling bodies, , CuCl 2 , Cu­(OH) 2 , , and (CH 3 COO) 2 Cu . One of these works also compared CuCl, Cu­(OH) 2 , CuO, and CuSO 4 as copper sources for the preparation of triethoxysilane .…”
