制备方法与用途

概述

有机含氢三烷氧基硅烷是有机硅化学与工业中的重要中间体之一，在有机硅工业中仅次于有机卤硅烷。其化学通式为HSi(OR)3，其中R通常为小于4个碳原子的直链烷烃。

应用

三乙氧基硅烷中的Si-OC2H5键可通过水解缩合转化为聚硅氧烷；而Si-H键则可在铂催化剂催化下与一系列烯、炔类单体发生硅氢加成反应，生成各种有机硅偶联剂（Y(CH2)n Si X3）、有机硅封端固化物、醚以及聚丙烯酸酯密封胶和粘合剂等产品。这些化合物还适用于制备许多高纯度的有机硅化合物，例如改性的硅烷密封剂、抗雾剂、拒水剂、硅烷偶联剂（如乙烯基、环氧基及甲基丙烯酰氧基衍生物）和涂料材料。

用途

• 合成硅烷偶联剂的重要原料
• 可用于制造硅油、聚硅烷等
• 用作光导纤维材料
• 在铂催化剂存在下与烯烃进行硅氢加成反应，作为还原剂使用

  热不稳定的金属氢化物配合物如何即使在高温下也能产生高催化活性

  摘要：

  尽管它们在醚溶剂中不稳定，但有机钛氢化物催化剂已成功地用于中高温度（110°C）的催化，甚至在存在醇的情况下。通过计算（键离解能（BDE）分析和再生的能量分布）和实验（EPR研究和动力学研究）以及加氢脱氟化氢（HDF）的具体实例表明，尽管长期以来人们一直相信Ti-H的再生使用硅烷从Ti-F键形成的键是endergonic的。Ti-H物质的低浓度对于这些系统的催化稳定性至关重要。催化中的静止状态是Ti-F物种。用于再生的最有希望的硅烷不是具有最强Si-F键的硅烷，而是在Si-F和Si-H BDE中表现出最大差异的硅烷。

  of simple and complex 1-alkenes with a variety of hydrosilanes. Catalysts derived from MesNQpy exhibited low activity. Fe-RPQpy derived catalysts favor hydrosilylation, whereas Co-RPQpy based catalysts favor dehydrogenative silylation. Catalysts derived from CoX2(iPrPQpy) convert hydrosilanes and ethylene to vinylsilanes. Related experiments were conducted on propylene to give propenylsilanes.
