Enediynes were first studied by Bergman and are known to undergo thermal intramolecular cyclization to benzene 1, 4-diradical or “dehydroaromatic” intermediates. 1 While the primary impetus for enediyne research remains focused on their biological activity as antitumor agents, 2 others have reported using enediynes in a polymerization scheme. 3, 4 Tour detailed the synthesis of linear poly (phenylenes) and poly (naphthalenes) by thermolysis ...
