Abstract
1,4-Bis[N-methyl(dibutoxyphosphonyl)-1-(2-furyl)]diaminobenzene and 4,4'-bis[N-methyl (dibutoxyphosponyl)-1-phenyl]benzidine have been synthesized through addition of dibutyl phosphite to Schiff bases (N,N'-difurfurylidene-p-phenylenediamine and N,N'-dibenzylidene-benzidine, respectively) in the presence of sodium butoxide or triethylamine. The compounds have been characterized by elemental analysis, TLC and IR spectra. A detailed analysis of their 1H-NMR spectra (1D and COSY) has been carried out.
