  不对称三烷氧基硅烷醇的简便合成：（RO）2（R'O）SiOH

  摘要：

  三烷氧基硅烷醇（RO）3 SiOH可用作过渡金属配合物中的配体，因为它们为二氧化硅支撑的金属位点或热解前体方法的前体提供了模型。但是，它们的合成大多限于对称的，其中所有RO配体均相同。然而，不对称取代的三烷氧基硅烷醇可以通过促进络合物的结晶，降低结晶学的无序性，改变所制备的络合物的热性质以及使侧基官能团的添加而提供比其对称对应物显着的优势。本文中，使用咪唑作为促进剂，提出了一种不对称的三烷氧基硅烷醇（RO）2（R'O）SiOH的简单通用合成方法。

  超极化 29Si 核磁共振检测硅烷醇和硅烷的反应性

  摘要：

  硅烷醇和硅烷是合成硅基材料的关键前体和中间体。虽然通过29 Si NMR 光谱对其进行表征和定量已受到极大关注，但该技术受到29 Si 自然丰度低及其灵敏度低的限制。在这里，我们描述了一种使用 p-H 2超极化29 Si 的方法。观察到的信号增强在 11.7 T 下接近 3000 倍，在玻尔兹曼条件下需要很多天的测量才能获得可比较的结果。利用所得信号来监测三（叔丁氧基）硅烷醇与三氟甲磺酸酐在T 1校正过程中的快速反应，从而实现快速定量。这些结果展示了一种量化硅材料合成中动态过程和中间体的新途径。

  Metal silicates or phosphates are deposited on a heated substrate by the reaction of vapors of alkoxysilanols or alkylphosphates along with reactive metal amides, alkyls or alkoxides. For example, vapors of tris(tert-butoxy)silanol react with vapors of tetrakis(ethylmethylamido)hafnium to deposit hafnium silicate on surfaces heated to 300° C. The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250° C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.
