Acidity constant determination of novel drug precursor benzothiazolon derivatives including acyl and piperazine moieties
(Pergamon-Elsevier Science LTD, 2013)In this study, protonation and deprotonation behaviors of eight new drug precursor benzothiazolon derivatives in all of acidic and basic scale (super acidic, pH, super basic regions) are analyzed by using UV-visible ... -
Intramolecular Hydrogen Bonding and Tautomerism in Schiff Bases: Synthesis, Spectroscopic and Theoretical Studies of N-(2,2 '-Methylenebis(4-methoxyphenyl)salicylidene and N-(2,2 '-Methylenebis(4-methoxyphenyl)-2-oxonaphthalidene-methylamine
(Asian Journal Of Chemistry, 2014)The new Schiff bases (4 and 5) were synthesized respectively from the reaction of 2,2'-methylenebis(4-aminomethoxybenzene) (3) with salicylaldehyde and 2-hydroxy-1-naphthaldehyde. The products have been characterized by ... -
New NO donor ligands and complexes containing furfuryl or crown ether moiety: Syntheses, crystal structures and tautomerism in ortho-hydroxy substituted compounds as studied by UV-vis spectrophotometry
(Elsevier Science BV, 2015)NO donor ligands were prepared by the condensation of methoxy substituted salicylaldehyde with 5-methylfurfurylamine (I and 2) and 4'-aminobenzo-15-crown 5 (3-5). New crown ether ligands of Schiff base type (3-5) containing ... -
