Synthesis of Tetracoordinated Silicon Directly from Natural SiO_2 and Characterization of its Structure

研究了直接从无定型二氧化硅出发 ,与乙二醇、氢氧化钾反应 ,低温合成高反应活性的五配位硅钾化合物 ,然后再与氯化苄 (C6H5CH2 Cl)反应制备四配位硅化合物 ,并对合成的物质作了红外光谱、核磁共振 (1H、13C)。

An high reactive pentacoordinate organic silicon complex was prepared from natural silica, ethylene glycol and potassium hydroxide. Then a novel tetracoordinated silicon was synthesized by the reaction of benzyl chloride with the reactive pentacoordinated silicon complex. The product was characterized and analyzed by FTIR, 1 H, 13 C NMR, EA etc.
