A blue shift was observed in the absorption maxima of protonated retinal Schiff base. The shift is due to electrostatic interaction of a non-conjugated positive charge, located in the vicinity of the ionone moiety, with the polyene chromophore.

The reduction of Schlff bases to form secondary amines has been accomplished by catalytic hydrogenatzon' and by various reagents such as maqneslum in 3 methano12, LiAlH4 , 4 and NaBH4 . More recently, [Fe3(C0)12] was reported to effective for the reaction 5 . We found that the reduction of various c
