Synthesis of New Ferrocenyl 1,3-diazabicyclo[3.1.0]hex-3-ene Derivatives

In this work, several new derivatives of ferrocenyl bicylic aziridine photochromic compounds have been prepared from the premade ketoaziridines and ferrocene carboxaldehyde in the presence of ammonium acetate in absolute ethanol via one-pot, three-component reaction. The structures of the newly synthesized compounds were established on the basis of IR, NMR and UV-Vis spectral studies. The newly synthesized compounds exhibit interesting photochromic behavior in the solid phase and solution state. The photochromic behavior of the prepared compounds has been investigated by UV-Visible spectral data.
