Abstract
A new synthetic route to face-to-face ferrocene polymers is studied. This route involves stepwise construction of a monomer unit by coupling cyclopentadienyl copper dimethyl sulfide at -25 ℃ with 4-(n-decyl)-1,8-diiodonaphthalene. The resulting mixture of 1-cyclopentadienyl-4- and 1-cyclopentadienyl-5-(n-decyl)-8-iodonaphthalene is then converted to the corresponding ferrocene by successive treatment with base and ferrous chloride. Finally, the remaining iodosubstituents are replaced by cyclopentadienyl groups by treatment with CpCuSMe2. Polymerization of the monomer is carried out by continuous treatment with base and ferrous chloride. The polymer with 17 ferrocene units is obtained. This stepwise synthetic route is milder than the previous palladium-catalyzed and can be used for the synthesis of the higher molecular weight polymers.
