标题:非晶硅:对旧材料的新见解
摘要:通过在高沸点极性和非极性溶剂(如二甘醇二甲醚或壬烷)中用熔融钠处理四卤硅烷six 4(x = Cl,F)来合成非晶硅,得到棕色或黑色固体,对合适的试剂具有不同的反应性.关于它们的技术相关性,研究了它们对氧气,空气,湿气,含氯反应伙伴rcl(r = H,Cl,Me)和醇的稳定性.特别是,与甲醇的反应是提供重要产品的多功能工具.除了形成四甲氧基硅烷外,硅的甲醇分解在环境条件下还会释放氢气,因此适用于分散制氢.竞争性插入的meo  ħ相对于我oh键可反应生成h和/或甲基取代的甲氧基官能硅烷.此外,由于四甲氧基硅烷在熔融钠上的热分解,诸如me N Si(ome)4-N(n = 0-3)之类的化合物可以轻松以超过75%的产率获得.根据我们的系统研究,我们确定了以优异的(n = 0:100%)达到可接受的收率(n = 1:51%;n = 2:27%)的甲氧基硅烷me N Si(ome)4-N的反应条件.;

摘要:A process for synthesis of an organosilicon compound is provided herein. Also, novel organosilicon compounds prepared by the present process is provided herein. The process comprises the reaction of a halosilane with an organofunctional alkyl halide in the presence of a metal catalyst, a promoter, and an optional co-catalyst. The process provides an efficient synthetic route to produce organosilicon compounds. The process also allows synthesis of organosilicon compounds with a plurality of different functional groups.

摘要:Silicatein is an enzyme of silicate-forming organisms used for the synthesis of their silicate scaffold. The present invention relates to the use of highly-expressed and highly active recombinant silicatein, silicatein isolated from natural sources after gene induction as well as silicatein-fusion proteins for the synthesis of amorphous silicon dioxide (silicic acids and silicates), siloxanes as well as modification of these compounds and their technical use.
