“…The -NH proton signal was detected as a triplet at 8.63-8.60 (1H, t, J = 5.8 Hz) for compound 9 (see Supplementaryinformation). These results are highly consistent with values for similar compounds [7,10,25,28]…”

“…The electronic absorption spectra of the new bis(thiosemicarbazones) based on Schiff base derivatives (1)(2)(3)(4)(5)(6)(7)(8)(9)(10) show that in all obtained products absorption bands appeared in the range of 256-406 nm in dimethylsulfoxide (see Figures S28-S36 in compound 1 (258 nm). This transition is a characteristic benzenoid (B) band of the aromatic structure [32].…”

“…They are used as versatile intermediates for synthesizing numerous moieties as well. Thiosemicarbazones have shown numerous medicinal properties and biological activities such as anticonvulsant [1], antituberculosis [2], urease inhibitory [3], anticancer [4], antiviral [5], antimicrobial [1], antibacterial [6], and antioxidant activity [7][8][9][10][11].…”

Schiff-base-bearing new bis(thiosemicarbazone) derivatives were prepared from terephthalaldehyde and various thiosemicarbazides. FT-IR, 1 H NMR, 13 C NMR, and UV-Vis spectroscopic methods and elemental analysis were used to elucidate the identification of the synthesized molecules. The in vitro antioxidant activity of the synthesized compounds was analysed with the 1,1-diphenyl-2-picryl hydrazyl free-radical-trapping process. The synthesized compounds exhibited lower antioxidant activity than the standard ascorbic acid. IC 50 values of the synthesized molecules measured from 3.81 ± 0.01 to 29.05 ± 0.11 µ M. Among the synthesized compounds, compound 3 had the best antioxidant activity. Moreover, this study explained the structure-activity relationship of the synthesized molecules with different substituents in radical trapping reactions.

“…Sulfur and nitrogen donors would coordinate the metal center to form bident, trident and even polyvalent ligands and thereby create complexes of distinct geometry and characteristics to change or improve their biological characteristics. [8,9]. In the literature, semicarbazones have been generally less studied than thiosemicarbazones.…”

The green synthetic processes have synthetized five Cr(III), Mn(II), Fe(III), Co(III) and Ni(II) complexes. In the current study, their synthesis by ball mining is decorated in a simple one-pot synthesis, cost efficiency, easy to measure for commercial manufacture, effective synthesis conditions such as moderate temperature and shorter length, thus preventing further by-products which could cause environmental harm, and being environmentally friendly as it is. All five complexes are well-defined, polyncrystalline materials as their Powder X-ray diffraction patterns indicate. The characterization of these complexes had been Fourier Transform Infrared Spectroscopy(FT-IR), 1H-13C Nuclear magnetic resonance, Scanning Electron Microscopy (SEM), electronic absorption spectral studies as well as magnetic studies and Powder XRD techniques.

Thiosemicarbazone Complexes of Uranium(IV)

The first homoleptic thiosemicarbazone complexes of uranium were isolated by reacting uranium tetrachloride in a salt metathesis or acid-base reaction with four equivalents of Na(BzTSC) or H(BzTSC) (BzTSC = benzylthiosemicarbazone), carrying a non-methylated (L1), monomethylated (L2) or dimethylated (L3) terminal amino group, in moderate yields. [U-(BzTSCNH 2) 4 ] (1), [U(BzTSCNH(CH 3)) 4 ] (2) and [U(BzTSCN(CH 3) 2) 4 ] (3) show a remarkable stability towards air, with oxidation potentials in THF between + 0.43 and + 0.53 V and reduction potentials between À 2.53 and À 2.67 V vs. ferrocene/ferrocenium. The simple methylation of the terminal amino group of the ligand allows for controlled changes in the coordination environments of the complexes. Thermogravimetric analyses indicate that the complexes are stable up to 155°C.
