标题:High pressure synthesis of sulfur-selenium fulvalenes
发明人：OKAMOTO YOSHIYUKI; WOJCIECHOWSKI PIOTR S
权利人:KOPPERS CO INC
摘要: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.

摘要: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.

标题 :Process for preparing tetraselenofulvalenes, and conductive salts obtained therefrom
发明人：COWAN DWAINE O; BLOCH AARON N; BECHGAARD KLAUS
权利人:UNIV JOHNS HOPKINS
摘要:A multistep process for preparing tetraselenofulvalenes involving the synthesis of 1,3-diselenole-2-selones and -2-thiones from diselenocarbamates and α-haloketones followed by coupling of the selone or thione using a dechalkogenizing reagent. New highly conductive salts obtained by coupling certain tetraselenofulvalenes with acceptor compounds are also disclosed.
