摘要

The syntheses of five phosphorus-substituted acetic acids have been carried out and the acidity of each has been determined. By application of a linear free energy correlation, approximate polar substituent constants (u*) for each of the phosphorus substituents have been determined. These studies indicate that the di-n-butoxyphosphono, diethoxyphosphono, and diphenylphosphono groups (u*= 1.74, 2.18, and 1.68) are ...
