Abstract
A process is disclosed for one-step preparation of substituted tetrathiafulvalenes by reaction of carbon disulfide with acetylenic compounds under pressures of at least about 1,000 atmospheres. Substituted tetrathiafulvalenes made by this process are particularly useful as precursors to very pure tetrathiafulvalene, a compound which can complex with tetracyano-p-quinodimethane to form a charge-transfer salt having very high electrical conductivity.
