“…Most of the applications of formazans are based on their spectral and electrochemical properties. Because of this, we focused our studies on the spectral and electrochemical behaviors of various substituted formazans [17][18][19][20][21]. In our previous work, cyclic voltammetric and chronoamperometric behaviors of 3-(m-, p-nitrophenyl)-1,5-diphenylformazans were investigated over the potential range of -2 to 0 V to negative potentials, and their electrochemical behaviors were investigated in cathodic region [17].…”

1-[(NO 2 , COOH)-substituted phenyl]-3,5-diphenylformazans were synthesized. The compounds were characterized by infrared (IR), ultraviolet-visible (UV-vis), 1 H nuclear magnetic resonance (NMR), 13 C NMR spectra, elemental analysis, and cyclic voltammetry. From the UV-vis spectra of substituted formazans it was seen that k max values were shorter than the k max value of unsubstituted formazan. It was observed that the shift values were dependent on the type and position of the substituents. A correlation between Hammett substituent coefficients and k max values was obtained. The oxidation peak potentials of substituted formazans were found more anodic than that of unsubstituted formazan. The oxidation mechanism was a single step for the NO 2 -substituted formazans, and two steps for COOH-substituted formazans.

“…Ni 2+ complexes of formazans were prepared and characterized by Tezcan et al [70][71][72] and the electrochemical investigations were carried out using cyclic voltammetry, linear sweep voltammetry and chronoamperometry. The structures of these formazans were elucidated by elemental analysis GCMS, FTIR and their spectral behavior were investigated using 1 HNMR, 13 CNMR and UV-visible spectral data.…”

“…Hydrazones and their metal complexes have widespread application in technology and analytical chemistry (Tezcan et al, 2008;Mattson et al, 1947). Hydrazones are formed when hydrazines condense with aldehydes and ketones by the condensation of aldehydes (or substituted aldehydes) with phenylhydrazine (or substituted phenylhydrazine) and typically are crystalline compounds with sharp melting points (McMurry, 2003;Todeschini et al, 1998).…”

A B S T R A C TIn the present work, we reported a novel thiadiazoline sulfonamide derivatives and their metal complexes were efficiently synthesized based on N-phenyl 2-pyridine carbohydrazonoyl halide. Synthesized compounds were elucidated by elemental analysis and spectral data. The newly synthesized compounds were evaluated for their in vitro antimicrobial activity against Gram negative (Escherichia coli and Pseudomonas aeruginosa), Gram positive (Staphylococcus aureus and Bacillus subtilis) bacterial strains and fungal strain Saccharomyces cerevisiae. The minimum inhibitory concentration of the synthesized compounds against various microorganisms was also determined. The synthesized thiadiazoline sulfonamide derivatives and metal complexes had superoxide dismutase-like activity and inhibited superoxide radical generation. Moreover, these organic compounds induced a wide range of DNA and protein degradation processes, based on agarose gel and sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses, respectively.
