Methods for acidizing subterranean formations may include introducing into a wellbore penetrating the subterranean formation having a temperature of about 275° F. or greater a treatment fluid comprising an aqueous fluid, a Lewis acid catalyst and a precursor; wherein the precursor is selected from the group consisting of a saccharide, a saccharide derivative, and a combination thereof; and reacting the precursor and the Lewis acid catalyst to yield an organic acid in a portion of the subterranean formation, a portion of the wellbore, or both.
