Abstract
2,3-Diiodonaphthalene (5) and 2-bromo-3-iodonaphthalene (6) were readily synthesized in two steps by iodination of the corresponding bis(hexachlorocyclopentadiene) adducts 1 and 3 of naphthalene and 2-bromonaphthalene, in methanesulfonic acid, followed by retro Diels-Alder reaction combined with sublimation.
