Published: Nov. 15, 2022

This review summarizes the data on synthesis of coordination compounds containing two or more different metal ions based fluorinated β-diketonates. Heterometallic systems are high interest in terms their potential use catalysis, medicine and diagnostics, as well development effective sensor devices functional materials. Having a rich history chemistry, β-diketones well-known ligands generating wide variety heterometallic complexes. In this context, we focused both synthetic approaches to β-dicarbonyl with additional centers possible transformations complexation reactions.

Synthesis, Structure, and Properties of a Copper(II) Binuclear Complex Based on Trifluoromethyl Containing Bis(pyrazolyl)hydrazone

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(17), P. 9414 - 9414

Published: Aug. 30, 2024

A new complex of copper(II) with methyl-5-(trifluoromethyl)pyrazol-3-yl-ketazine (H2L) was synthesized the composition [Cu2L2]∙C2H5OH (1). Recrystallization sample from DMSO yielded a single crystal [Cu2L2((CH3)2SO)] (2). The coordination compounds were studied by single-crystal X-ray diffraction analysis, IR spectroscopy, and static magnetic susceptibility method. data obtained indicate that polydentate ligand is coordinated both acyclic nitrogen heterocyclic atoms. cytotoxic activity 1 investigated on human cell lines MCF7 (breast adenocarcinoma), Hep2 (laryngeal carcinoma), A549 (lung HepG2 (hepatocellular MRC5 (non-tumor lung fibroblasts). shown to have pronounced dose-dependent cytotoxicity towards these LC50 values in range 0.18–4.03 μM.

Perfluoroalkyl Chain Length Effect on Crystal Packing and [LnO8] Coordination Geometry in Lanthanide-Lithium β-Diketonates: Luminescence and Single-Ion Magnet Behavior

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(11), P. 9778 - 9778

Published: June 5, 2023

Functionalized perfluoroalkyl lithium β-diketonates (LiL) react with lanthanide(III) salts (Ln = Eu, Gd, Tb, Dy) in methanol to give heterobimetallic Ln-Li complexes of general formula [(LnL3)(LiL)(MeOH)]. The length fluoroalkyl substituent ligand was found affect the crystal packing complexes. Photoluminescent and magnetic properties solid state are reported. effect geometry [LnO8] coordination environment heterometallic on luminescent (quantum yields, phosphorescence lifetimes for Dy complexes) single-ion magnet behavior (Ueff is revealed.

Exploring Three Avenues: Chemo- and Regioselective Transformations of 1,2,4-Triketone Analogs into Pyrazoles and Pyridazinones

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(18), P. 14234 - 14234

Published: Sept. 18, 2023

A convenient approach to substituted pyrazoles and pyridazinones based on 1,2,4-triketones is presented. Chemo- regiocontrol in condensations of t-Bu, Ph-, 2-thienyl-, CO2Et-substituted 1,2,4-triketone analogs with hydrazines are described. The direction preferential nucleophilic attack was shown be switched depending the substituent nature triketone as well reaction conditions. acid temperature effects selectivity were revealed. Regiochemistry heterocyclic core formation confirmed by NMR XRD studies. facile construction motifs bearing acetyl (or) carbethoxy groups suggests them promising mono- or bifunctional building blocks for subsequent transformations.

Abstract A wide range of α-aryl-α-diazophosphonates were easily prepared via modified diazo transfer reaction. Benzylphoshonates reacted with tosyl azide (TsN3) in the presence potassium tert-butoxide (KOtBu) to afford diazophosphonates yields up 93% (generally 70–80%). Aryldiazophosponates successfully explored for synthesis 5-aryl-substituted pyrazol-3-carboxylates one pot by 1,3-dipolar cycloaddition alkyl acrylates followed NaH treatment. The second stage led elimination diethoxylphosphoryl moiety aromatization cycle.
