1,3-Diethynyladamantane and a method of forming same by brominating adamantane to yield 1,3-dibromoadamantane, subjecting vinyl bromide to Friedel-Crafts alkylation with the 1,3-bidromoadamantane to form 1,3-bis(2,2-dibromoethyl)adamantane and subjecting the 1,3-bis(2,2-dibromoethyl)adamantane to dehydrohalogenation to yield the 1,3-diethynyladamantane. 1,3-Diethynyladamantane can be polymerized to produce strong, thermally stable resins suitable for advanced aerospace structural applications, as matrices for carbon-carbon systems and as electrical insulators. It can also be co-polymerized with 1-ethynyladamantane to yield similarly useful resins.
1,3-二乙炔基金刚烷及其制备方法是通过溴化金刚烷生成1,3-二溴基金刚烷,然后将乙烯溴化物与1,3-二溴基金刚烷进行弗里德尔-克拉夫特芳基化反应以形成1,3-双(2,2-二溴乙基)金刚烷,最后将1,3-双(2,2-二溴乙基)金刚烷进行脱卤化反应得到1,3-二乙炔基金刚烷。1,3-二乙炔基金刚烷可以聚合成强度高、热稳定的树脂,适用于先进航空航天结构应用、作为碳-碳系统的基质和电绝缘体。它还可以与1-乙炔基金刚烷共聚合以生成同样有用的树脂。
