Synthesis, crystal structure, optical and electrochemical properties of novel diphenylether-based formazan derivatives
Türkoğlu, Gülsen; Berber, Halil; Kani, İbrahim (Royal Soc Chemistry, 2015)In this study, formazans 5a-5h were synthesized by coupling the reactions of substituted phenylhydrazone compounds 3a-3h with diazonium salt of 4-chloro-2-phenoxybenzenamine (4). The substituted phenylhydrazones 3a-3h were ... -
A theoretical search on metal-ligand interaction mechanism in corrosion of some imidazolidine derivatives
Öğretir, Cemil; Çalış, S; Bereket, G; Berber, Halil (Elsevier Science BV, 2003)The interaction mechanism of some imidazolidine derivatives with metallic Zn in gas phase, using semiempirical methods, was studied at elevated temperature and the obtained data were used to search a possible correlation ... -
Theoretical studies on the structure of [(1-aza-2-benzimidazol-2-ylprop-1-enyl)amino]aminomethane-1-thione
Poyraz, Mehmet; Berber, Halil; Öğretir, Cemil (Arkat Usa Inc, 2007)The tautomerisation and acid-base properties of [(1-aza-2-benzimidazol-2-ylprop-1-enyl) amino]aminomethane-1-thione were studied both in the gas and aqueous phase to elucidate the structure of this compound. The computed ... -
A theoretical study of substituent effects on tautomerism of 2-hydroxybenzimidazoles
Öğretir, Cemil; Yarlıgan, S; Berber, Halil; Arslan, T; Topal, S (Springer-Verlag, 2003)The geometries, relative stabilities of some 4(7) and 5(6) substituted 2-hydroxybenzimidazole derivatives were calculated with full geometry optimization using AM1 and PM3 in aqueous phase. With the exception of molecules ... -
UV-spectral changes for some azo compounds in the presence of different solvents
Sidir, Yadigar Gülseven; Sidir, İsa; Berber, Halil; Tasal, Erol (Elsevier Science BV, 2011)The electronic absorption spectra of four azo dyes with different substituents (such as Cl, I, OH) are determined at room temperature in twenty-one solvents with different polarities. The electronic transitions of azo dyes ...
