Dynamic behaviour of 1,n′-disubstituted ferrocenes

1,n′-Disubstituted ferrocenes with ketone/phthalimido (2) and ketone/amine substituents (3) were synthesised and characterised by IR, 1H NMR, 13C NMR, VT 1H NMR, UV/Vis spectroscopy, mass spectrometry and cyclic voltammetry. The molecular structure of 2 was confirmed by X-ray crystal structure determination. The dynamic behaviour was experimentally studied in solution and theoretically by DFT calculations. The thermal stability of the ketone/amine derivative 3 was investigated using thermal analyses.
