4,4′-Bis[N-methyl(diethoxyphosphonyl)-1-(2-furyl)]benzidine and 4,4′-bis[N-methyl(diisopropoxyphosphonyl)-1-(2-furyl)]benzidine have been synthesized through addition of diethyl phosphite and diisopropyl phosphite, respectively, to the Schiff base N,N′-difurfurylidenebenzidine. The compounds have been characterized by elemental analysis, TLC and IR spectra. A comparable study of their 1H-NMR spectra and 1H-NMR spectra of 4,4′-bis[N-methyl(diethoxyphosphonyl)-1-phenyl]benzidine has been carried out. Some 1H-NMR data of 4,4′-bis[N-methyl(dimethoxyphosphonyl)-1-phenyl]diaminodiphenylmethane, 4,4′-bis[N-methyl(diethoxyphosphonyl)-1-phenyl]diaminodiphenylmethane and 4,4′-bis [N-methyl(diisopropoxyphosphonyl)-1-phenyl]diaminodiphenylmethane in DMSO-d6, solution are also presented.

Some new Schiff bases derivates from 2-furaldehyde and phenylenediamines(L1-3) and their complexes with lanthanum (La), samarium (Sm ), gadolinium (Gd) and erbium (Er) have been synthesized. These complexes with general formula [Ln(L1-3)2(NO3) 2]NO3.nH2O (Ln = La, Sm, Gd, Er) were characterized by elemental analysis, UV-Vis, FT-IR and fluorescence spectroscopy, molar conductivity and thermal analysis. The metallic ions werefound to be eight coordinated. The emission spectra of these complexes indicate the typical luminescence characteristics of the Sm(III), La(III ), Er(III) and Gd(III) ions.
