1,3 Bis[N-methyl(diethoxyphosphonyl) - 1 - (2-furyl)]diaminobenzene has been synthesized through the addition of diethyl phosphite to the Schiff base NN'-difurfurylidene-m-phenylenediamine. The compound has been characterized by elemental analysis, TLC, IR, and H-1, C-13, and P-31 NMR spectra. The NMR studies show that the reaction product is a mixture of two diastereomers (meso and racemic forms). The P-31 NMR data revealed 61% content for the predominant and 39% for the minor form.
