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

Abstract

Syntheses, Chemical and Electrical Properties of Tetrathiafulvalene with a 1,6‐Methano[10]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‐methano[10]annulene‐dicarbaldehyde 1 . The oxidation of 3 in the presence of HBF 4 in Et 2 O yielded the salt 4 , elimination of a hydride anion with triphenylmethylium tetrafluoroborate the salt 5 , and elimination of a proton in 5 with Et 3 N the tetrathiafulvalene 6 with a 1,6‐methano[10]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.
