  Synthesis of organosilicon polymers by using the Lewis-acid-catalyzed trans-allylsilylation of alkynes

  摘要：

  The HfCl4 catalyzed polymerization of allyl(4-ethynylphenyl)dimethylsilane (1a) proceeded smoothly to give poly[dimethyl-(1,4-pentadienyl)phenylsilane] (2a), and the HfCl4 catalyzed reaction of 1-aallyl-2-(4-ethynyphenyl)-1,1,2,2-tetramethyl-disilane (1b) afforded poly[1,1,2,2-tetramethyl-1-(1,4-pentadienyl)-2-phenyldisilane] (2b). These polymerization reactions proceeded via the stereoselective trans-allylsilylation of the 4-ethynyl group attached to the aromatic ring. (C) 2004 Elsevier Ltd. All rights reserved.

  There is provided a method of synthesizing an organosilicon compound. This method comprises polymerizing, as a starting material, allyl-(4-alkynyl-phenyl) silane represented by the following general formula (3) in a solvent selected from methylene chloride, chloroform, carbon tetrachloride and 1,2-dichloroethane and under the presence of hafnium tetrachloride to obtain an organosilicon compound represented by the following general formula (1). (wherein R is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or a phenyl group, R's may be the same or different and are individually an alkyl group having 1 or 2 carbon atoms or a phenyl group, and n is an integer of 4 to 2500).

  提供一种合成有机硅化合物的方法。该方法包括在甲烷氯、氯仿、四氯化碳和1,2-二氯乙烷等溶剂中，以铪四氯化物存在下，聚合以下通式（3）所表示的烯丙基-（4-炔基苯基）硅烷作为起始物质，以获得以下通式（1）所表示的有机硅化合物。（其中，R是氢原子、具有1至6个碳原子的烷基或苯基，R可以相同或不同，分别是具有1或2个碳原子的烷基或苯基，n是4至2500的整数。）
