    Electrochemical behaviour of 5-(furan-2-yl)-4-(p-tolyl)-2,4-dihydro-1,2,4- triazole-3-thione by using glassy carbon electrode
    (Chemical Publishing Co., 2007) Dilgin, Yusuf; Cansiz, Ahmet; Çetin, Ahmet; Kutulay, Pelin; Oral, Ayhan; Yilmaz, Selahattin
    The electrochemical study of a thiotriazole compound, 5-(furan-2-yl)-4-(p- tolyl)-2,4-dihydro-1,2,4-triazole-3-thione (TTA) was performed by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) using glassy carbon electrode (GCE) as working electrode and an Ag/AgCl reference electrode. The dependence of the current on pH and scan rate was investigated in the Britton Robinson Buffer. The best results for electrooxidation of TTA were obtained in basic media (pH 11.0 containing 5 % DMSO). This compound display one irreversible oxidation peak, which is attributed to a dimerization process involving the formation disulphide derivative.

    Electrochemical behaviour of 5-benzyl-4-(4'-methylphenyl)-4H-1,2,4-triazole-3-thiol by voltammetry
    (Indian Chemical Soc, 2007) Dilgin, Yusuf; Koparir, Metin; Cetin, Ahmet; Cansiz, Ahmet; Yilmaz, Selehattin; Giray, Didem
    The electrochemical study of a thiotriazole compound, 5-benzyl-4-(4'-methylphenyl-4H-1,2,4-triazole-3-thioI (TTA) was made with cyclic voltammetry (CV) and differential pulse voltammetry (DPV) using glassy carbon electrode (GCE) as working electrode and an Ag/AgCl reference electrode in the Britton- Robinson buffer. The best results for electrooxidation of TTA were obtained in basic media (in 10% ethanol-0.2 M NaOH). This compound display one irreversible oxidation peak, which is attributed to a dimerization process involving the formation of disulphide derivative (EC mechanism).

    Preparation and characterization of Co(II), Ni(II) and Cu(II) complexes of a ligand containing 1,3,4-thiadiazole groups
    (Springer, 2007) Ozturk, Omer Faruk; Cansiz, Ahmet; Koparir, Metin
    (1R,2R)-1,2-bis-(5-amino-1,3,4-thiadiazole-2-yl)ethane-1,2-diol (L) has been prepared by the reaction of thiosemicarbazide with (2R,3R)-(+)-tartaric acid (I) and phosphorous oxychloride, and its complexes with Co(II), Ni(II) and Cu(II) have been obtained. The structures of the ligand and its complexes have been established by i.r., H-1- and C-13-n.m.r. spectra, u.v.-vis-nir spectroscopy, elemental analyses, T.g.-D.t.a. and magnetic susceptibility measurements.
