标题:芳烃离子催化全烷基化硅烷的卤代脱烷基化
摘要:"有机硅"在自然界中并不存在,但现代化学很难想象没有硅与碳结合的情况.虽然含硅商品化学品(例如通过"直接工艺" 1,2,3,4产生的那些)看起来很简单,但选择性制备芳基取代和烷基取代(官能化)硅化合物(称为硅烷)并非易事.氯硅烷如 Me 4− N Sicl N ( N = 1-3) 以及 Sicl 4 ( N = 4) 是合成含硅分子的常见起点.然而这些方法常常遇到具有挑战性的分离问题5 .相反,具有四个烷基的硅烷被认为是合成的死角.在这里,我们介绍了芳烃离子催化的卤代脱烷基化反应,可有效地将 Me 4 Si 和相关的季硅烷转化为各种官能化衍生物.该反应使用烷基卤和芳烃(共)溶剂:烷基卤是卤化物源,最终与芳烃进行弗里德尔-克来福特烷基化以再生催化剂6,而芳烃离子则充当强布朗斯台德酸原脱烷基化步骤7 .例如,在硅药物前体的合成中,证明了自上而下的卤代烷基化方法相对于报道的自下而上程序的优势.此外,连接到烷基链上的相当惰性的me

权利人:MOMENTIVE PERFORMANCE MAT INC
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:The present invention relates to a fluorurated siliconic polymer with controlled molecular weight and viscosity having a structure composed by means of the chaining of oligo-dialkylsiloxane building-blocks having a limited and selected molecular weight and alternated mainly with siloxane units containing a fluorurated substituent and - to a marginal degree - inert siloxane units or substituted by unsaturated groups. When the latter are present -they are used for subsequent reactions of clamping or cross-linking. The present invention relates, moreover, to a synthesis method of the mentioned polymer and its use.

摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.
