Novel phosphorus-containing hydritzones: (2-furfurylidene)phosphorohydrazidic acid diethyl ester (1), [1-(2-furyl)ethylidene]phosphorohydrazidic acid diethyl ester (2), salicylidene phosphorohydrazidic acid diethyl ester (3), (4-hydroxybenzylidene) phosphorohydrazidic acid diethyl ester (4), [1-(1-naphthyl)ethylidene)phosphorohydrazidic acid diethyl ester (5) and [1-(2-naphthyl)ethylidene]phosphorohydrazidic acid diethyl ester (6) have been synthesized by condensing phosphorohydrazidic acid diethyl ester with the corresponding aldehydes or ketones. The compounds have been characterized by elemental analysis, TLC, IR, 1 H and 13 C (ID and COSY) NMR spectroscopy. The IR spectra show the presence of intramolecular and intermolecular hydrogen bonding in 3 and 4, respectively. The 13 C NMR spectra indicate the presence of geometric isomers for compounds 1-6.
