The synthesis of bis(p-nitrophenyl)carbonate has been studied through the reaction of bis(trichloromethyl)carbonate (triphosgene) with p-nitrophenol in biphasic median benzene-NaOH(aq) and in an organic solvent (methylene chloride) in the presence of triethylamine as HCl receiver and catalyst. The reaction in homogeneous mediun has been monitored by FT-IR spectroscopy following the evolution in time of the nu (C=O) vibration bands at different molar ratios of the reactants and triethylamine. The product was obtained in the best yield 97%. This method has been succesfully applied for the synthesis of the other two isomers (o- and m-) of bis(nitrophenyl) carbonate and the products have been characterized by melting point, IR spectroscopy, H-1- and C-13-NMR spectroscopy, electron impact MS, and TLC.
