Abstract
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-dibromoadamantane 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 copolymerized with 1-ethynyladamantane to yield similarly useful resins.
