Abstract
A new member of 3-aryl phosphacoumarins family have been synthesized by the way of Knoevenagel condensation of 4-(diethylamino) salicylaldehyde and diethyl 4-nitrobenzylphosphonate with consequent cyclization. Chemical properties of obtained product were illustrated by reduction of nitro group. All synthesized compounds were fully characterized by NMR spectroscopy and high-resolution mass spectrometry
