Özet

The acid dissociation constants (K-a) of eight novel biologically active benzothiazole Schiff bases were determined by UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The calculated acidity constants, pK(a) values, were evaluated in structure elucidation and protonation - deprotonation mechanisms. The prototropic tautomerism was also studied.
