Japanese Patent JPH0521914

B2

The novel complex of the formula I (I) can be produced for example by electrochemical oxidation of 2-fluoro-5,6,11,12-tetraselenotetracene in the presence of an inert organic solvent and a bromide-containing electrolyte. The novel 2-fluoro-5,6,11,12-tetraselenotetracene can for its part be produced by reacting 2,3-naphthalenedicarboxylic anhydride, in the presence of a Friedel-Crafts catalyst, with fluorobenzene to 2-(4-fluorobenzoyl)-naphthalene-3-carboxylic acid; cyclizing this to 2-fluoro-5,12-naphthacenequinone; reducing the 2-fluoro-5,12-naphthacenequinone to 2-fluorotetracene; reacting the 2-fluorotetracene with sulfuryl chloride to 2-fluoro-5,11- or 2-fluoro-6,12-dichlorotetracene; and finally reacting the last-mentioned at elevated temperature with selenium to obtain 2-fluoro-5,6,11,12-tetraselenotetracene. The complex of the formula I is metallically conducting, and is distinguished by a stable metallic phase down to at least 5 DEG K. It can be used for example as an organic conductor element.
