Synthesen,chemische und elektrische Eigenschaften von Tetrathiafulvalen mit 1,6-Methano[10]annulen-Partialstruktur und von Chalcogendiimid-derivaten

Syntheses, Chemical and Electrical Properties of Tetrathiafulvalene with a 1,6-Methano10]annulene Moiety and of Chalcogendiimide-Derivatives The synthesis of the tetrathiafulvalene 6 has been described: the reaction of 1 with the benzenedithoil 2 yielded the bis-dithioacetal 3 of 1,6-methano10]annulene-dicarbaldehyde 1 . The oxidation of 3 in the presence of HBF₄ in Et₂O yielded the salt 4 , elimination of a hydride anion with triphenylmethylium tetrafluoroborate the salt 5 , and elimination of a proton in 5 with Et₃N the tetrathiafulvalene 6 with a 1,6-methano10]annulene moiety. The spectroscopic and electrochemical properties of 6 are described, and also the syntheses and properties of charge-trasnfer complexes 7 and 8 , including the properties of electric conductivity of 7 and 8 . the syntheses of 9-13 are reported and also their spectroscopic properties.
