Two antipyrine derivates, 4-(3, 4-dihydroxybenzylideneamino) antipyrine (DHBAP), and 4-
(2, 3, 4-trihydroxybenzylideneamino) antipyrine (THBAP), are structurally similar Schiff
bases derived from the condensation of 3, 4-dihydroxybenzaldehyde and 2, 3, 4-
trihydroxybenzaldehyde with 4-aminoantipyrine in methanol solutions. The compounds
were characterized by elemental analysis, FT-IR and UV–vis techniques. Density functional
calculations were carried out to further optimize and to characterize them. The calculated …
