The synthesis and characterisation of heterosubstituted aminoferrocenes

The synthesis of 1-bromo-1′-aminoferrocene is reported using a simple synthetic methodology. This compound serves as a useful precursor to other heterosubstituted aminoferrocenes. For example, (1′-amino)ferrocenecarboxylic acid has been obtained and is conveniently isolated in its C-protected form by lithiation of 1-bromo-1′-aminoferrocene, quenching with solid carbon dioxide and esterification of the resulting carboxylate with methanolic HCl. The new ligand 1-diphenylphosphino-1′-aminoferrocene has also been obtained using a similar methodology.
