摘　　要：以金属锂为催化剂,直接催化苯乙酮与三乙氧基硅烷的硅氢加成反应,将产生的硅醚水解,得到二级醇.结果表明,在室温条件下,以四氢呋喃为溶剂,三乙氧基硅烷为氢源,反应17h,苯乙酮的转化率达99%以上.The hydrosilylation reaction of acetophenone and triethoxysilane was catalyzed with lithium metal, and the secondary alcohol was obtained by silyl-ethers hydrolysis. The results indicated that the conversion of acetophenone was over 99% with tetrahydrofuran as the solvent and triethoxysilane as the hydrogen source after 17 hours reaction at room temperature.
