摘要：
Some new aryl phosphonic acid ethyl ester analogs of acetyl salicylic acids, and bis-p-aminophenoxy-benzo-phosphonic acid ethyl esters have been prepared in good yield. Characterization by spectroscopic techniques indicates that in the phosphorus NMR spectra a significant change in chemical shift values between the starting phenolic phosphonate and both the corresponding derivative is observed; thus this up-field shift is very diagnostic for this type of compounds.
