The two four-coordinate N-heterocyclic carbene (NHC) copper(I) complexes, [Cu(Ph-BenIm-methylPy)(POP)]PF6 (1), and [Cu(Ph-Im-methylPy)(POP)]PF6 (2), Ph-BenIm-methylPy = 3-benzyl-1-(6-methyl-pyridin-2-yl)-1H-benzimidazolylidene, Ph-Im-methylPy = 3-benzyl-1-(6-methyl-pyridin-2-yl)-1H-imidazolylidene, POP = bis[2-(diphenylphosphino)phenyl] ether have been synthesized and characterized. Those complexes exhibit blue to green emission with very high quantum yields and long excited-state lifetimes. The exptl. results reveal that the origin of emissive state at room temperature occurs from the combination of TADF and phosphorescence in which phosphorescence predominates TADF, and the corresponding emissive mechanisms were discussed. To the best of our knowledge, the combined emissions with high quantum yield close to ca. 100% have not been previously reported in this library of the four-coordinate NHC-Cu(I) complexes.

A series of Cu(I) pyridyl-imidazole (PyIm) complexes with different aryl groups (Ar = naphthalene (P2), phenanthrene (P3), and anthracene (P4)) attached on the pyridyl ring were synthesized and characterized. The influence of these organic chromophore groups on the photophys. properties of the resulting complexes is investigated. Complexes P2P4 show stronger light harvesting efficiencies in the visible region compared with the parent complex P1. The emitting state of complex P1 originates from the 3MLCT state with some 3LLCT character, while complexes P2 and P3 predominantly exhibit the 3LLCT character. For complex P4, the triplet emitting state is dominated by the 3(π → π) state localized on the anthryl moiety, together with a lesser contribution form the 3LLCT state. These changes in the photophys. properties were rationalized by DFT and TDDFT methods.

Wagener, Tobias;Lueckemeier, Lukas;Daniliuc, Constantin G.;Glorius, Frank research published 《 Interrupted pyridine hydrogenation: Asymmetric synthesis of δ-lactams》, the research content is summarized as follows. Metal-catalyzed hydrogenation is an effective method to transform readily available arenes into saturated motifs, however, current hydrogenation strategies are limited to the formation of C-H and N-H bonds. The stepwise addition of hydrogen yields reactive unsaturated intermediates that are rapidly reduced. In contrast, the interruption of complete hydrogenation by further functionalization of unsaturated intermediates offers great potential for increasing chem. complexity in a single reaction step. Overcoming the tenet of full reduction in arene hydrogenation has been seldom demonstrated. In this work the authors report the synthesis of sought-after, enantioenriched δ-lactams from oxazolidinone-substituted pyridines and water by an interrupted hydrogenation mechanism.

Wade, Nicola;Tehrani, Kamaleddin H. M. E.;Bruechle, Nora C.;van Haren, Matthijs J.;Mashayekhi, Vida;Martin, Nathaniel I. research published 《 Mechanistic Investigations of Metallo-β-lactamase Inhibitors: Strong Zinc Binding Is Not Required for Potent Enzyme Inhibition**》, the research content is summarized as follows. Metallo-β-lactamases (MBLs) are zinc-dependent bacterial enzymes that inactivate essentially all classes of β-lactam antibiotics including last-resort carbapenems. At present there are no clin. approved MBL inhibitors, and in order to develop such agents it is essential to understand their inhibitory mechanisms. Herein, we describe a comprehensive mechanistic study of a panel of structurally distinct MBL inhibitors reported in both the scientific and patent literature. Specifically, we determined the half-maximal inhibitory concentration (IC50) for each inhibitor against MBLs belonging to the NDM and IMP families. In addition, the binding affinities of the inhibitors for Zn2+, Ca2+ and Mg2+ were assessed by using isothermal titration calorimetry (ITC). We also compared the ability of the different inhibitors to resensitize a highly resistant MBL-expressing Escherichia coli strain to meropenem. These investigations reveal clear differences between the MBL inhibitors studied in terms of their IC50 value, metal binding ability, and capacity to synergize with meropenem. Notably, our studies demonstrate that potent MBL inhibition and synergy with meropenem are not explicitly dependent on the capacity of an inhibitor to strongly chelate zinc.

Vanga, Mukundam;Lalancette, Roger A.;Jaekle, Frieder research published 《 Controlling the Optoelectronic Properties of Pyrene by Regioselective Lewis Base-Directed Electrophilic Aromatic Borylation》, the research content is summarized as follows. Pyreno-annelated azaboroles I (5, X = C13H27, R = Ph, Et) and azaborines II (6, Y = C8H17, R = Ph, Et) were prepared by stepwise borylation-Suzuki coupling of pyrene and examined for their photophys. properties. Given that pyrene represents one of the most versatile chromophores, the development of new selective routes for its functionalization and tuning of its emission properties is highly desirable. Pyrene-based BN Lewis pair (LP)-functionalized polycyclic aromatic hydrocarbons (PAHs) were prepared by regioselective Lewis base-directed electrophilic aromatic substitution. The requisite 1,6-dipyridylpyrene ligands were accessed by Suzuki-Miyaura cross-coupling of 1,6-bis(pinacolatoboryl)pyrenes with 2-bromopyridine derivatives Subsequent electrophilic borylation with BCl3 in the presence of AlCl3 and 2,6-di-tert-butylpyridine as a hindered base produced the dichloroborane complexes, which were then in situ reacted with di-Ph or di-Et zinc. The presence or absence of alkyl chains in the 3,8-positions of the pyrene moiety determined the position of the B-C bond formation (2,7 in the non-K region vs. 5,10 in the K region) and thereby also the size of the BN heterocycle (five- vs. six-membered). The impact of the regioisomeric borylation on the electrochem., photophys. and structural properties was investigated and the conclusions supported by theor. calculations The rapid synthesis of derivatives that are borylated in the K region also suggests strong potential for the development of pyrene derivatives that are otherwise difficult to access.

Tsyrenova, Biligma D.;Khrustalev, Victor N.;Nenajdenko, Valentine G. research published 《 Synthesis of blue light emitting heterocycles via cyclization of 2-pyridine derived 4-azido-r1,2,3-triazoles》, the research content is summarized as follows. An efficient synthesis of 2-pyridine derived 4-azido-1,2,3-triazoles I (R = pyridin-2-yl, 6-bromopyridin-2-yl, 8-hydroxyquinolin-2-yl, 1,8-naphthyridin-2-yl, etc.; R1 = Ph, 4-methylphenyl, 4-fluorophenyl, 3,4-dichlorophenyl, etc.) was elaborated using the corresponding dichlorodiazadienes Cl2C=C(R)N=NR1 as precursors. The reaction of the prepared 2-azine substituted diazadienes with sodium azide permits the preparation of target triazoles I isolated in up to 92% yield. Subsequent thermal cyclization was studied. Elimination of mol. nitrogen promoted the cyclization of nitrene at the azine nitrogen. As a result, a family of 2H-[1,2,3]triazolo[4′,5′:3,4]pyrazolo[1,5-a]pyridin-5-ium-4-ides II (R2 = H, Me; R3 = H, Me, Br; R2R3 = -CH=CH-CH=CH-, -C(OH)=CH-CH=CH-, -CH=C(CH3)-CH=CH-, -N=CH-CH=CH-) was prepared The synthesized compounds II are members of a new heterocyclic system. Moreover, these compounds II are new attractive blue light emitting mols.

Tsybizova, Alexandra;Fritsche, Lukas;Gorbachev, Vladimir;Miloglyadova, Larisa;Chen, Peter research published 《 Cryogenic ion vibrational predissociation (CIVP) spectroscopy of a gas-phase molecular torsion balance to probe London dispersion forces in large molecules》, the research content is summarized as follows. We report a gas-phase mol. torsion balance that uses a conformational equilibrium to “weigh” London dispersion against a competing cation-π interaction, for which the readout is the shift in an N-H stretching frequency measured by cryogenic ion vibrational predissociation (CIVP) spectroscopy of electrosprayed pyridinium cations in a Fourier-transform ion cyclotron resonance trap. While frequency calculations with DFT, within the harmonic approximation, assist in the interpretation of the spectra, the observed complex spectrum most likely comes from a Fermi resonance of the N-H stretch with otherwise “dark” overtones of in-plane C-H wagging modes, as argued on the basis of comparison of the spectrum to those for a range of related cations with systematically varied substitution. An equilibrium in favor of the asym. conformer would suggest that the dispersion-corrected DFT calculations tested in this work appear to overestimate significantly the stability of the compact conformations favored by London dispersion in the gas phase, which would then pertain to the use of dispersion energy donors in the design of stereoselective reactions.
