Synthesis of mono-amino-functionalised ferrocene, ferrocene salts and ferrocenium salts.

A number of mono-amino-functionalised ferrocenes, ferrocene salts and a mono-amino-functionalised ferrocenium salt have been synthesised and characterised. This represents a novel method of accessing these important classes of molecules. In the cases of some of the ferrocene salts, there are some interesting structural features in the solid state. These include N–H⋯O and N–H⋯F hydrogen bonds.
