TETRATHIAPENTALENE AND TETRASELENAPENTTALENE COMPOUNDS Abstract of the Disclosure This application is concerned with tetrathiapentalene and tetrasalenapentalene compounds. Specifically, it is concerned with 1, 3, 4, 6-tetrathia-2, 5-dihetexo-pentalene and 1, 3, 4, 6 tetraselena-2, 5-dihetero-pentalene compounds having the formula or wherein X is S or Se; each of Y1 and Y2 is O, S, or Se; each or Z1 and Z2 is -SR, SeR ox = N? wherein R and Rr are H, alkyl, aryl, or together form a ring of carbon atoms; and An is the anion of a strong acid. These compounds are key synthetic intermediates for the preparation of tetrathiafulvalene and tetraselenafulvalene materials, in the art of producing organic conductors. |
