Abstract
Syntheses, Chemical and Electrical Properties of Tetrathiafulvalene with a 1,6‐Methano[10]annulene Moiety and of Chalcogendiimide‐DerivativesThe 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 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‐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.
