Naphthalene-1-sulfonic acid dimethylamides were treated with n-BuLi and elemental sulfur or selenium to afford dinaphtho[1,2-b:2′,1′-d] thiophenes and selenophenes, respectively. This is the first example of making two C-S/Se bonds and a C-C bond in a single step at room temperature and also demonstrates a useful method for the synthesis of both thiophenes and selenophenes on naphthalene. In the case of the reactions of elemental selenium, diselenides were also obtained along with dinaphtho[1,2-b:2′,1′-d] selenophenes. The structure of dinaphtho[1,2-b:2′,1′-d]thiophene was characterized by X-ray crystallography as a representative molecule.
