Ferrocene and its derivatives are very useful in the fields of chemistry, biomedicine materials. Herein, a ferrocene derivative was synthesized one step from benzotriazol-1-yl-oxytripyrrolidino-phosphonium hexafluorophosphate ferrocenecarboxylic acid. Its accurate structure determined by 1H 13C NMR further confirmed X-ray diffraction analysis corresponding single crystal.

The general synthetic strategy towards water-soluble biodegradable drug carriers and the properties that they must have are discussed. The syntheses of water-soluble biodegradable copolymers of lysine and aspartic acid as potential drug-delivering devices, having amine-functionalised side chains are then described. Covalent anchoring of carboxylic acid derivatives of the antineoplastic ferrocen...

The 7-ferrocenycarbonyloxy-1-heptanethiol (FcCO2C7SH) is synthesized using ferrocene carboxylic acid, 1,6-fibromohexane, and NaS, which is confirmed and separated by FT-IR, H NMR, and column chromatography. The basic redox (interfacial) properties are also studied of the self-assembled monolayers (SAMs) formed with this synthesized compound on polycrystalline gold electrode by Electrochemical Q...

The interaction of ferrocene-boronic acid with fructose is investigated in aqueous 0.1 m phosphate buffer at pH 7, 8 and 9. Two voltammetric methods, based on 1) a dual-plate generator-collector micro-trench electrode (steady state) and 2) a square-wave voltammetry (transient) method, are applied and compared in terms of mechanistic resolution. A combination of experimental data is employed to ...
