  Direct alkoxysilylation of alkoxysilanes for the synthesis of explicit alkoxysiloxane oligomers

  摘要：

  Direct alkoxysilylation, which is a powerful tool to provide explicit alkoxysiloxanes, is developed and its versatility is investigated. Siloxane pentamers Si[OSiR1(OMe)(2)](4) having various functional groups (R-1 = methyl, vinyl, phenyl, chloropropyl and n-butyl groups) were successfully obtained by direct alkoxysilylation of Si(OR)(4) (R= t-Bu, CHPh2). Thus, the versatility of the reaction is confirmed on organic functional groups R-1. Functional group tolerance of the reaction is discussed on the basis of electro-negativity of the R-1 groups. Alkoxysilylation of Si(Ot-Bu)(2)(OMe)(2) and Si(Ot-Bu)(OMe)(3) selectively gives trimer (MeO)(2)Si[OSiMe(OMe)(2)](2) and dimer (MeO)(3)SiOSiMe(OMe)(2), respectively. Thus, the feasibility on siloxane structure is also confirmed. Various siloxane compounds are synthesized by this newly developed reaction for the first time. (C) 2012 Published by Elsevier B.V.

  nanomaterials by stepwise reactions of Si−OR (R=alkyl) and Si−Cl groups. Intermolecular exchange of alkoxy and chloro groups between alkoxysilanes and chlorosilanes (functional group exchange reaction) provides an efficient and environmentally benign route to alkoxychlorosilanes. BiCl3 as a Lewis acid catalyst can promote the functional group exchange reactions more efficiently than conventional acid catalysts

  烷氧基氯硅烷在制备有机硅和二氧化硅以及通过Si-OR（R =烷基）和Si-Cl基的逐步反应制备基于硅氧烷的纳米材料方面具有重要的科学和工业意义。烷氧基硅烷和氯硅烷之间的烷氧基和氯基的分子间交换（官能团交换反应）为烷氧基氯硅烷提供了一种有效且对环境无害的途径。BiCl 3作为路易斯酸催化剂可以比常规酸催化剂更有效地促进官能团交换反应。对于具有较少数量的Si-CH 3基团的氯硅烷和对于具有较大数量的Si-CH 3基团的烷氧基硅烷，已观察到更高的反应性组。提出了反应机理并证明了烷氧基氯硅烷的选择性合成。这些发现还使我们能够合成具有四个不同取代基的有机三烷氧基硅烷。
