Theoretical substituent effects upon the acidity of the title compounds were investigated using STO ‐3 G basis sets augmented by diffuse functions for all oxygen atomic centers of the probe groups. The results are discussed in connection with the available gas‐phase data within a novel conception of attractive and repulsive substituent effects.
