Barrelene (bicyclo [2.2. 2] octa-2, 5, 7-triene, 1) is the formal Diels-Alder adduct of acetylene to benzene. 1 Since neither acetylene nor benzene is reactive in cycloaddition reactions, the synthesis of 1 requires the definition of both an efficient acetylene equivalent2 and of a reagent able to temporarily suppress the aromatic character of benzene, in such a way as to allow it to react as a diene. 3 In other words, this equals the definition of a synthon of ...
