Novel diesters of aminophosphonic acids containing furan and benzidine residue

Article abstract of DOI:10.1080/10426509908044976

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.
