Ethynylsilanes, RnSi(CCH)4-n (n = 0 to 3), can be prepared in satisfactory yields from RnSiCl4-n and HCCMgCl in tetrahydrofuran. Losses occur through (a) polymerization under the influence of the cyclic ether and (b) metallation of the ethynylsilanes to SiCCMgCl which provokes the formation of sila-acetylene chains and rings. Some of these compounds of higher molecular weight have been isolated
乙炔基硅烷R n Si(CCH)4-n(n = 0至3),可以由R n SiCl 4-n和HCCMgCl在四氢呋喃中以令人满意的产率制备。损失是通过(a)在环醚的影响下聚合和(b)乙炔基硅烷金属化成SiCCMgCl引起的,从而促使形成硅乙炔链和环。这些高分子量化合物中的一些已经被分离出来。

Abstract Bromomagnesium derivatives of ethynylsilanes [Me4–nSi(C≡CMgBr)n, n = 1–3] reacted with chloro(chloromethyl)dimethylsilane to give the corresponding (chloromethyl)(ethynyl)silanes [Me4–nSi(C≡CSiMe2CH2Cl)n, n = 1–3] which were converted to iodomethyl analogs by exchange reaction with sodium iodide. The reaction of the resulting (iodomethyl)(ethynyl)silanes with 1,3-benzothiazole-2-thiol afforded
摘要 乙炔基硅烷的溴镁衍生物 [Me 4– n Si(C≡CMgBr) n , n = 1–3] 与氯(氯甲基)二甲基硅烷反应得到相应的(氯甲基)(乙炔基)硅烷 [Me 4– n Si(C≡) CSiMe 2 CH 2 Cl) n , n = 1–3] 通过与碘化钠的交换反应转化为碘甲基类似物。所得(碘甲基)(乙炔基)硅烷与 1,3-苯并噻唑-2-硫醇反应得到新的乙炔基甲硅烷基甲基噻唑基硫化物。
