标题:甲硅烷基氢化:一种战略方法,可以直接使用通用的甲硅烷基饱和饱和碳和杂环化合物
摘要:我们报告了一种通过芳烃加氢将易得的甲硅烷基化芳烃转化为甲硅烷基化饱和碳和杂环的方法.范围包括烷氧基和卤代甲硅烷基取代基.甲硅烷基可被衍生为多种功能,并在有机合成,材料科学以及制药,农业化学和香料研究中得到应用.但是,目前的技术很难获得甲硅烷基化的饱和(杂)循环.氢化的产率取决于硅胶添加剂的量.这种二氧化硅效应还可以显着改善以前公开的高度氟化芳烃的氢化方法(例如,氢化至全顺式c 6 H 6 F 6).

标题:Metallocene ligands, metallocene compounds and metallocene catalysts, their synthesis and their use for the polymerization of olefins
发明人：SCHOTTEK JOERG; PACZKOWSKI NICOLA STEFANIE; WINTER ANDREAS; SELL THORSTEN
权利人:NOVOLEN TECH HOLDINGS CV
摘要:A catalyst system includes a metallocene compound having the formula R 9 L 1 L 2 M 1 R 1 R 2 wherein R 9 is a bridge between ligands L 1 and L 2 and M 1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R 1 and R 2 can be hydrogen or aliphatic or aromatic groups. Bridge R 9 can include silicon, germanium or tin. The metallocene compound of the invention as synthesized has a racemic to meso isomer ratio of greater than 5 to 1, thereby precluding the need for subsequent separation of the meso isomer.
