Anthmnilic acid 9 amI odibromobenzme 14 annelated with two bicyclo[2.2.2]octene units were synthesized as the precursors for titled benzyne 3. The generation of 3 was confkmed by trapping with forao and its derivative. In the absence of trapping agent, benzyne 3 generated by diamtization of 9 gave a
One-electron oxidation of 1,4-dithiin annelated with bicyclo[2.2.2]octene units (3) by SbF5 afforded stable radical cation salt 3'+SbF6 -. The X-ray crystallography indicated that the dithiin ring of 3 '+ is planar in agreement with the theoretical prediction. The ESR coupling constant (as) due to 3
