The synthesis and the H-1-NMR characterization of the title compounds is here described, These derivatives were prepared starring from salicylaldehyde which was alkylated at the phenolic hydroxyl group by the Williamson procedure and then converted into the corresponding alpha-hydroxy phosphoryl compound by triethyl phosphite in dry dioxane under a gaseous stream of HCl. The alpha-hydroxy phosphonic acid diethyl esters were then caused to react in dry CH3CN at 50 degrees C for a couple of days in order to yield the desired urethane, possessing a phosphonic group, The interest of the synthesized compounds lies in their potential biological and insecticide properties and as model compounds of phosphorus containing polyurethanes.
