The design, synthesis and electrochemical behaviour of an oligomer consisting of linked thymine-functionalised ferrocene units are reported, which, as a so-called form of ferrocene nucleic acid (FcNA), acts as a structural mimic of DNA.

Preparation of N-(alk-1-enyl) nucleobase compounds by Horner and Horner–Wadsworth–Emmons reactions
A series of new N9-(alk-1-enyl)adenines and N1-(alk-1-enyl)thymines has been prepared by Horner reactions of the new phosphine oxides N9-(diphenylphosphorylmethyl)adenine and N1-(diphenylphosphorylmethyl)thymine derivatives 13aâc, or HornerâWadsworthâEmmons reactions of the corresponding new phosphonates 14aâb, with benzaldehyde and various ketones. Yields were highest for the Horner reactions (10â79%), and were limited by steric hindrance, enolization of the ketones, and decomposition of some of the N1-(alk-1-enyl)thymines in the presence of excess base (NaH). Butanal gave mixtures of products under Horner conditions, probably because aldol reactions intervened.
