Spectroscopic Determination of Acid Dissociation Constants of N-Substituted-6-acylbenzothiazolone Derivatives
(Amer Chemıcal Soc, 2011)
The acid dissociation constants of twelve novel drug precursor N-substituted-6-acylbenzothiazolone derivatives were determined by using the UV-vis spectroscopic technique. The protonation and deprotonation behaviors of the ...
Studies on the electronic absorption spectra of some monoazo derivatives
(Pergamon-Elsevıer Scıence Ltd, 2011)
The electronic absorption spectra of a series of azo dye compounds containing -Cl, -SO(3)H and -OH groups were recorded in twenty one solvents with different polarities. The solvents were selected to cover a wide range of ...
Quantum chemical studies on tautomerism and basicity behavior of some 1,2,4-triazole derivatives
(Scıentıfıc Technıcal Research Councıl Turkey-Tubıtak, 2010)
The acidity constants, relative stabilities, and tautomeric equilibrium constants of some 1,2,4-triazole derivatives were determined using the density functional theory (DFT) with the B3LYP method and 6-311G(d,p) basis ...
