Chirality is one of the most important intrinsic properties of (supra)mols. In this study, the authors obtained enantiomeric metallo-supramol. octahedra without using any chiral sources. Such cages were self-assembled by prochiral trispyridine ligand L , L = 2,7,12-tri(3-pyridyl)-5,5′,10,10′,15,15′-hexaethyltruxene, based on a C3h truxene core and CuII salts. Crystallization of the cages with BF4– as counterions afforded racemate crystals; while crystallizations of cages with ClO4– and OTf– as counterions resulted in conglomerates with spontaneous resolution Three types of chirality were observed in each cage, including planar chirality of the truxene core, axial chirality from the pyridyl and truxene moieties, and propeller chirality of the pyridyl-CuII coordination sites. The cages reported here are among the largest discrete synthetic metallo-supramols. ever reported with chiral self-sorting behavior. Remarkably, the chiral cages exhibited very slow racemization even at low concentrations, suggesting their high stability in solution In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2COA of Formula: C2CuF6O6S2).

Electronic Band Structure and Electrocatalytic Performance of Cu3N Nanocrystals was written by Wang, Li-Chen;Liu, Bo-Heng;Su, Chung-Yi;Liu, Wei-Szu;Kei, Chi-Chung;Wang, Kuan-Wen;Perng, Tsong-Pyng.

High-d. discrete Cu3N nanocrystals were deposited on XC-72 C black by plasma-enhanced at. layer deposition (PEALD). This heterostructured noble-metal-free catalyst served as a high-performance electrocatalyst for enhanced O reduction reaction (ORR). The electronic band structure of Cu3N was determined by UPS and UV-visible spectrophotometry. The work function (Φ) of the Cu3N nanocrystals is 5.04 eV, which is lower than that of Pt (∼5.60 eV). With lower energy barrier, Cu3N would exhibit stronger electron transfer to cause ORR than typical Pt catalyst. The UPS anal. also confirmed the synergistic coupling effect between the Cu3N nanocrystals and the C support. Coupled with the XC-72, the Cu3N200/C showed even smaller Φ (=4.34 eV) than pure Cu3N nanocrystals. Thus, the Cu3N200/C electrocatalyst prepared with 200 ALD cycles exhibited similar ORR catalytic activity, significantly improved mass activity, and potentially greater durability than its Pt/C counterpart in alk. solution The fabrication of Cu3N by PEALD and its good performance in ORR suggest a promising alternative of nonnoble-metal electrocatalyst for application in fuel cells.

The product selectivity, production rates and the required process conditions are important for technol. development. Selective lignin depolymerization on the prime β-O-4 motif provides an opportunity to obtain valuable functionalized phenolic monomers. Diol-stabilized acidolysis of lignin with sulfuric acid, triflic acid or triflate salts is a proven β-O-4 cleavage methodol. that forms acetals by trapping of released reactive aldehydes. For future scale-up, a better understanding of the prime reaction pathways and how these can be controlled upon changing reaction parameters is required. By using β-O-4 model compounds and ytterbium(III) triflate as catalyst, starting material conversion and product formation including two key intermediates, the diol adducts (in this study, ethylene glycol as the diol) and the vinyl ethers, were accurately monitored, allowing for detailed kinetic modeling. Over the selected temperature range (80-150°C), higher temperatures led to higher overall carbon balance and selectivity for the main desired acetal product. The kinetic modeling allowed for establishing a detailed reaction network with activation energies and rate constants These collectively led to new insights into the key steps involved in the diol-stabilized β-O-4 motif acidolysis and how the reaction selectivity can be manipulated by controlling the reaction temperature, and the ethylene glycol and water content. Al. The elucidation on reaction kinetics and networks constitutes a further step in the design of a diol-stabilized lignin acidolysis process.

And the article was included in Dalton Transactions in 2017.Application of 14781-45-4 This article mentions the following:

Mol. magnets based on copper(II) ions and stable nitroxide radicals exhibit promising switchable behavior triggered by a number of external stimuli; however, their spin-state-correlated optical properties vital for photoinduced switching were not profoundly studied to date. Herein, the electronic absorption spectra of single crystals of three representatives of this unique family were studied exptl. and theor. in the visible and near-IR regions. The color of the complexes is mainly determined by optical properties of the nitroxide radicals, whereas the Cu(hfac)2 fragment contributes to the near-IR range with the intensity smaller by an order of magnitude. The thermochromism of these complexes evident upon thermal spin state switching is mainly caused by a spectral shift of the absorption bands of the nitroxides. The vibrational progression observed in the visible range for single crystals as well as for solutions of pure nitroxides is well reproduced by DFT calculations, where the C-C stretching mode governs the observed progression. The anal. of the spectra of single crystals in the near-IR region reveals changes in the energy and in the intensity of the copper(II) d-d transitions, which are well reproduced by SOC-NEVPT2 calculations and owe to the flip of the Jahn-Teller axis in the coordination environment of copper. Further strategies for designing bidirectional magnetic photoswitches using these appealing compounds are discussed.

Molybdenum alkylidyne complexes that contain a 3,3′-di-t-butyl-5,5′,6,6′-tetramethyl-1,1′-biphenyl-2,2′-diolate ([Biphen]2-) ligand was written by Schrock, Richard R.;Jamieson, Jennifer Y.;Araujo, James P.;Bonitatebus, Peter J.;Sinha, Amritanshu;Lopez, L. Pia H.. And the article was included in Journal of Organometallic Chemistry in 2003.Application In Synthesis of (S)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol This article mentions the following:

The reaction between K2[Biphen] ([Biphen]2- = 3,3′-di-tert-butyl-5,5′,6,6′-tetramethyl-1,1′-biphenyl-2,2′-diolate) and Mo(NArCl)(CH-t-Bu)(OTf)2(dme) (ArCl = 2,6-Cl2C6H3) in the presence of ten equiv NEt3 gave Mo(NHArCl)(C-t-Bu)[Biphen] (4a) in 40-50% yield. Addition of K2[S-Biphen] to Mo(NArCl)(CHCMe2Ph)(OTf)2(THF) in THF gave Mo(NHArCl)(CCMe2Ph)[S-Biphen] (4b) in ∼40% yield. An x-ray crystal study of 4b confirmed the proposed structure and also revealed that one ortho chloride approaches within 2.93 Å of the metal approx. trans to the alkylidyne ligand. Addition of one equiv H2[Biphen] to Mo(CCH2SiMe3)[N(i-Pr)Ar”]3 (Ar” = 3,5-dimethylphenyl) produced Mo(CCH2SiMe3)[Biphen][N(i-Pr)Ar”] in situ, which when treated with one equiv 1-adamantanol gave a mixture of Mo(CCH2SiMe3)[Biphen](OAd) (9) and three equiv HN(i-Pr)Ar”, from which 9 could be isolated as a beige powder in 46% yield. An x-ray study of 9 confirmed that it is a pseudotetrahedral species in which the MoC bond length is 1.707(15) Å and the MoC-C angle is 168.3(11)°. Addition of ten equiv 2-butyne or 3-hexyne to a pale yellow solution of 9 produced the molybdacyclobutadiene complexes Mo(C3R3)[Biphen](OAd) (R = Me or Et; 10a and 10b, resp.) in high yield. Both 10a and 10b decompose slowly in solution, even in the presence of added alkyne. An x-ray structure of the decomposition product of 10a revealed it to have the stoichiometry of 10a plus one addnl. equiv of 2-butyne. The most unusual feature of the structure of this alkyne complex is a fusion of the C3Me3 portion of the metallacyclobutadiene ring to carbons in position 5 and 6 in the [Biphen]2- backbone to create a σ allyl linkage. These results suggest that Mo biphenolate alkylidyne complexes are not likely to be stable under conditions where alkynes are metathesized.
