Abstract

See full text

A process is disclosed for one-step preparation of sulfur-selenium fulvalenes by reaction of an acetylenic compound with carbon selenide sulfide or with a mixture of carbon diselenide and carbon disulfide under pressures of at least about 1,000 atmospheres. Fulvalene compounds made by the process are characterized in having at least one sulfur atom and at least one selenium atom in the ring structure of the fulvalene compound. Substituted diselenadithiafulvalenes made by this process are precursors to very pure diselenadithiafulvalene which is useful in preparing charge-transfer salts.
