And the article was included in Journal of the American Chemical Society in 2022.Formula: C10H2CuF12O4 This article mentions the following:

The copper-catalyzed enantioselective intermol. radical 1,2-carboamination of alkenes with readily accessible alkyl halides was an appealing strategy for producing chiral amine scaffolds. The challenge arised from the easily occurring atom transfer radical addition between alkyl halides and alkenes and the issue of enantiocontrol. A radical alkene 1,2-carboamination with sulfoximines in a highly chemo- and enantioselective manner was described. The key to the success of this process is the conceptual design of a counterion/highly sterically demanded ligand coeffect to promote the ligand exchange of copper(I) with sulfoximines and forge chiral C-N bonds between alkyl radicals and the chiral copper(II) complex. The reaction covered alkenes bearing distinct electronic properties, such as aryl-, heteroaryl-, carbonyl- and aminocarbonyl-substituted ones and various radical precursors, including alkyl chlorides, bromides, iodides and the CF₃ source. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Formula: C10H2CuF12O4).

copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Copper catalyst has received great attention owing to the low toxicity and low cost. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Formula: C10H2CuF12O4

And the article was included in Inorganica Chimica Acta in 2017.Quality Control of copper(ii)hexafluor-2,4-pentanedionate This article mentions the following:

Four new transition complexes were obtained by using triazole nitronyl nitroxide radical as ligand. [Mn(4-Me-3-Nit-trz)(hfac)₂] (1) and [M(4-Me-3-Nit-trz)(hfac)₂]₂ [M = Co(II) 2, Ni(II) 3, Cu(II) 4; 4-Me-3-Nit-trz = 2-[3-(4-methyl-l,2,4-triazolyl)]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluoroacetylacetone] were characterized structurally and magnetically. The metal ions in the four complexes are all in six-coordinated environment with four O atoms from two hfac^– ligands, and one radical O atom and one triazole N atom from a two teeth 4-Me-3-Nit-trz ligand. The magnetic behaviors for 1–3 indicate that the metal ions and the direct coordinated radicals are antiferromagnetically coupled (J_Mn-rad = -49.61 cm^-1, for 1; J_Co-rad = -22.36 cm cm^-1, for 2; J_Ni-rad = -115.39 cm^-1, for 3), whereas a ferromagnetic coupling between the Cu(II) ion and the nitroxide group (J_Cu-rad = 3.45 cm^-1) is observed in 4. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Quality Control of copper(ii)hexafluor-2,4-pentanedionate).

Field supported slow magnetic relaxation in a quasi-one-dimensional copper(II) complex with a pentaheterocyclic triphenodioxazine was written by Korchagin, D. V.;Ivakhnenko, E. P.;Demidov, O. P.;Akimov, A. V.;Morgunov, R. B.;Starikov, A. G.;Palii, A. V.;Minkin, V. I.;Aldoshin, S. M.. And the article was included in New Journal of Chemistry in 2021.Application In Synthesis of copper(ii)hexafluor-2,4-pentanedionate This article mentions the following:

A new copper(II) complex (1) was obtained by the reaction of a sterically crowded 2,4-di-(tert-butyl)-9-chloro-benzo[5,6][1,4]oxazine[2,3-b]phenoxazine bridging ligand with Cu(II) hexafluoroacetylacetonate. Compound 1 is a quasi-one-dimensional complex in which the Cu(hfac)₂ moieties are co-crystallized with the triphenodioxazine mols. through only weak Cu···N short intermol. interactions (the Cu···N distances are 2.732 and 2.752 Å). The magnetic AC susceptibility data show that in spite of the absence of zero-field splitting in the Cu(II) ion with S = 1/2, the compound demonstrates a slow magnetic relaxation behavior at a weak applied magnetic field (H_DC = 500 Oe). The EPR spectra and DC magnetic measurements show the strong axial anisotropy of the g-tensor. The temperature dependence of the relaxation time is well described by the combination of one-phonon direct and two-phonon Raman processes. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Application In Synthesis of copper(ii)hexafluor-2,4-pentanedionate).

Reactivity of a formal Cu(III)-alkyl species toward aniline: a DFT investigation was written by Xu, Xinyu. And the article was included in Dalton Transactions in 2020.Product Details of 14781-45-4 This article mentions the following:

Although formal Cu(III) species were extensively proposed as key intermediates in a wide range of Cu-catalyzed reactions, the precise reactivity of these species remains inconclusive. Commonly, a formal reductive elimination mechanism is proposed for the product formation step. Through theor. study of the reactivity between a formal Cu(III)-alkyl species and aniline, a S_N2-like mechanism could also be responsible for coupling product formation. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Product Details of 14781-45-4).

copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents has turned up as an exceedingly robust synthetic tool. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.Product Details of 14781-45-4
