SYNTHESIS, SPECTROSCOPIC CHARACTERIZATION, SOLVENT-DEPENDENT KETO–ENOL TAUTOMERISM, AND ELECTROCHEMICAL BEHAVIOR OF OXADIAZOLE- AND TRIAZOLE-LINKED β-KETO ESTERS
Abstract Four β-keto ester derivatives containing 1,2,4-triazole (A7 and A8) or 1,3,4-oxadiazole (A13 and A14) thioether units were synthesized by S-alkylation of the corresponding thiol/thione precursors with ethyl 4-chloro- 3-oxobutanoate in ethanol using sodium acetate as a stoichiometric basic additive. The proposed structures are supported by FT-IR, 1H NMR, and 13C NMR data, including disappearance […]
ELECTROCHEMICAL SYNTHESIS OF NANOMAGNETITE MODIFIED WITH BIOCOMPATIBLE SURFACTANTS
Abstract Magnetic nanoparticles are currently gaining significant attraction in various fields, including modern engineering and ecology, particularly in biomedical, therapeutic, and diagnostic technologies. An environmentally friendly electrochemical synthesis method was used to produce magnetic nanoparticles. Iron sulfate was dissolved in a mixture of water-ethanol, while polyvinylpyrrolidone (PVP) was used to enhance the biocompatibility of the […]
