Özet

The acid dissociation constants, pK(a) values, of 12 biologically active 6-[p- or p- and m-substituted] phenyl-4,5-dihydro-3(2H)-pyridazinone derivatives were computed using semi-empirical methods. Correlations between the experimental and computed acid dissociations constants were found to be satisfactory. (C) 2003 Published by Elsevier B.V.
