Abstract
1,3,5,7-Tetrakis(4-iodophenyl)adamantane was reacted with 2-methyl-3-butyn-2-ol and phenylacetylene under Pd-catalyzed Heck coupling cnnditions to give the two corresponding tetraacetylene derivatives. Deprotection of the first gave the derivative with free terminal acetylenes. Thermal cure of both acetylene-containing monomers was monitored by FTIR. Both NMR and FTIR confirmed the presence of adamantane in the otherwise all-aromatic structures. TGA indicated that these highly crosslinked materials began to degrade at ca. 450 and 490°C, respectively, in air
