And the article was included in Chinese Journal of Chemistry in 2022.Formula: C2CuF6O6S2 This article mentions the following:

The first Cu-catalyzed 1,2,5-trifunctionalization of abundant terminal alkynes is realized by merging hydrogen atom transfer and traceless directing strategy with SR as a transient group, delivering highly functionalized aldehydes in moderate to excellent yields with broad substrate scope. The synthetic utility of this method was demonstrated by the gram-scale reaction and downstream transformations of the resultant products. Given the high efficient installation of three different functional groups in a single reaction, it can serve as a very attractive method for rapidly assembling complex mols. from readily available starting materials. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Formula: C2CuF6O6S2).

Copper(II) trifluoromethanesulfonate (cas: 34946-82-2) belongs to copper catalysts.

And the article was included in Dalton Transactions in 2022.Reference of 34946-82-2 This article mentions the following:

Phthalocyanine that has four peripheral 2-methoxyphenyl substituents at the α-position and its Zn(II) and Cu(II) complexes were synthesized. Chem. oxidation by the Cu(II) ion and electrochem. oxidation of these metal complexes were studied spectrophotometrically in acetonitrile. The UV-visible absorption spectra of these metal complexes and their one-electron oxidized π-cation radicals showed no concentration dependence, indicating that these species exist as monomers in solution Kinetics of the thermal electron transfer reaction from each phthalocyanine complex to Cu²⁺ and the photoinduced electron transfer reaction of the Zn(II) phthalocyanine complex with V(V) and V(IV) Schiff base complexes were studied using conventional spectrophotometric and transient absorption techniques, and the electron transfer rate constants were analyzed using the Marcus cross relation. The obtained rate constants of the electron self-exchange reaction between the parent phthalocyanine complexes and their π-cation radicals were in the order of 10⁹ to 10¹¹ M^-1s^-1 at T = 298.2 K. These large electron self-exchange rate constants are consistent with the phthalocyanine-centered redox reactions where small reorganization energies are required with little structural change during the electron transfer process.

The spatial variations in chem. composition and transport properties of the interphase formed on reactive metal electrodeposits dictate the stability and reversibility of electrochem. cells that use reactive metals as anodes. Here we report on the influence of carbonate and fluorinated electrolytes infused with ethers as additives on the phys.-chem. characteristics and reversibility of metallic lithium (Li) during early stages of electrodeposition and later stages of deep cycling of Li metal anodes. We show that a feasible strategy for achieving and sustaining kinetically enhanced interphases through the cycle life of Li electrodeposits is by simultaneous use of sacrificial electrolyte components that undergo electroreduction to enrich the interphase with fluorinated species in tandem with cleaning electrolyte components that promote dissolution and removal of less desirable carbonaceous compounds We demonstrate that this approach translates to high electrochem. reversibility during deep cycling of the Li metal anode and improved performance of Li metal batteries.
