Abstract
A process is disclosed for one-step preparation of substituted tetraselenafulvalenes by reaction of carbon diselenide with acetylenic compounds under pressures of at least about 1,000 atmospheres. Substituted tetraselenafulvalenes made by this process are useful as precursors to very pure tetraselenafulvalene and are useful in forming complexes with certain inorganic anions to provide charge-transfer salts having very high electrical conductivity.
