reactions of trichlorosilane and acetylene in an autoclave were carried out in the presence of platinized asbestos or of pyridine. In the case of the former catalyst, 1,2-di(trichlorosilyl)ethane was obtained exclusively. In the case of the latter, on the other hand, the principal product proved to be a mixture of 1,2- and 1, 1-di(trichlorosilyl)-ethane. The addition of trichlorosilane to vinyltri-chlorosilane
三氯硅烷和乙炔在高压釜中的加成反应在铂化石棉或吡啶的存在下进行。在前一种催化剂的情况下,仅获得 1,2-二(三氯甲硅烷基)乙烷。另一方面,在后者的情况下,主要产物被证明是 1,2- 和 1, 1- 二(三氯甲硅烷基)-乙烷的混合物。在玻璃管中存在四吡啶氯化镍 (II) 的情况下,将三氯硅烷添加到乙烯基三氯硅烷中也会导致形成两种异构体的混合物。因此,可以认为在吡啶存在下高压釜中的反应过程是通过玻璃管中的反应重现的。这种情况似乎类似于先前报道的三氯硅烷氰乙基化的情况。
