Item SINTEZA ŞI CARACTERIZAREA FIZICO-CHIMICĂ A UNOR BIS-TIOSEMICARBAZONE NOI(CEP USM, 2021-04-22) Cebotari, DianaSix new bis-thiosemicarbazones ligands were synthesized with rigid or flexible organic links between the two thiosemaicarbazones moieties. Such ligands have been designed for the synthesis of polymetallic coordination complexes. They were synthesized by the condensation reaction between aldehydes and substituted thiosemicarbazides in alcohol, using acetic acid as a catalyst. To determine the structure, composition and purity, the products were characterized using nuclear magnetic resonance spectoscopy, mass spectroscopy and elemental analysis.Item SYNTHESIS AND CHARACTERI S ATIONS OF SIX NEW BIS - THIOSEMICARBAZONE LIGANDS(CEP USM, 2020) Cebotari, Diana; Haouas, Mohamed; Floquet, Sébastien; Gulea, AurelianSixnew bis-thiosemicarbazones ligands were synthesized with rigid or flexible organic chemical links between the two thiosemicarbazones moieties. Such ligands have been designed for the synthesis of polymetallic coordination complexes. They were synthesised by the condensation reaction between aldehydes and substituted thiosemicarbazides in alcohol, using acetic acid as a catalyst. To determine the composition, the products were characterised by 1H, 13C and 15 N nuclear agnetic resonance, mass spectrometry and elemental analysis.
