The equilibrium constants for ring–chain tautomerism in a series of 8-aroyl-1-naphthoic acids in dioxan have been determined by an i.r. spectroscopic method and have been correlated with the substituent constants σ1 and σR0 using a modified Hammett equation. The observed pKa values, which have been measured in 80%(w/w) 2-methoxyethanol–water, have been corrected for these tautomeric equilibria to give the true pKaT value. The effect of substitution on the latter values have been assessed using… CONTINUE READING
