Ferrocene containing polymers

Polymers with pendent ferrocene units are synthesized by radical and anionic methods. It has been demonstrated that polymer‐analogous reactions are an attractive alternative to prepare those polymers. Polymers with ferrocene units in the main chain are available from interfacial condensation reaction between ferrocene‐1,1′‐dicarbonic acid dichloride with α, ω‐diamines. Addition of ferrocene‐1,1′‐dithiol onto norbornadiene yields a polymer with repeating units from ferrocene disulfide and norbornene and nortricyclane end‐groups. End‐capping reactions of α, ω‐dimercapto‐telechelics with vinylferrocene yield polymers with ferrocene end‐groups.
