  Cp 2 TiCl 2 / n BuLi催化的氢硅烷转化为烷氧基硅烷

  摘要：

  Cp 2 TiCl 2和n BuLi的组合为乙醇，异丙醇，叔丁醇和苯酚醇解硅烷硅烷n-HexSiH 3，PhMeSiH 2，Ph 2 SiH 2和PhMe 2 SiH提供了有效的催化剂。增加醇或硅烷上取代基的空间体积通常需要更长的反应时间和/或升高的温度。所有的SiH键都被乙醇转化为SiOEt基团，仲硅烷中的一个SiH键和叔硅烷中的两个SiH键被叔丁醇取代。包括频哪醇，2,4-戊二醇和2,5-己二醇的二醇与PhRSiH 2反应（RMe，Ph）分别得到1，3-二氧杂-2-硅环戊烷，-己烷和-庚烷。通过伯硅烷和三醇的缩合形成笼状结构的尝试是不成功的。Cp 2 TiCl 2 / n BuLi促进PhRSiH 2的水解，当RMe时，当定量R yield Ph和线性二硅氧烷与三硅氧烷的混合物以及环聚硅烷时，可以定量产率生产硅氧烷。其他质子试剂包括酸，硫醇，胺和可烯化的酮均未反应。还确定了反应参数

  A surface acoustic wave (SAW) performs a rapid, label-free detection of biological species. Biosensing and detection of multiple analytes multiplexed by an array of sensing lanes is configured to enable bio-amplification using engineered DNA encoded libraries as the probe through a phage display procedure to enhance specificity, capture statistics for the detection, screening and analyzing of the analyte in vitro. A biochemical formulation minimizes the limit of detection (LOD) at a threshold magnitude on the order of a femtomolar concentration. Additional enhancement of the apparatus is achieved by use of an analog front end to amplify biochemical events.
