Cleavage of carbon-halogen bonds via either single-electron reduction or atom transfer is a powerful transformation in the construction of complex mols. In particular, mild, selective hydrodehalogenations provide an excellent follow-up to the application of halogen atoms as directing groups or the utilization of atom transfer radical addition (ATRA) chem. for the production of hydrocarbons. Here we combine the mechanistic properties of photoredox catalysis and silane-mediated atom transfer chem. to accomplish the hydrodebromination of carbon-bromide bonds. The resulting method is performed under visible light irradiation in an open vessel and is capable of the efficient reduction of a variety of unactivated alkyl and aryl substrates.

Author is Musacchio, Andrew J.; Nguyen, Lucas Q.; Beard, G. Hudson; Knowles, Robert R..

While olefin amination with aminium radical cations is a classical method for C-N bond formation, catalytic variants that utilize simple 2° amine precursors remain largely undeveloped. Herein we report a new visible-light photoredox protocol for the intramol. anti-Markovnikov hydroamination of aryl olefins that proceeds through catalytically generated aminium radical intermediates. Mechanistic studies are consistent with a process involving amine oxidation via electron transfer, turnover-limiting C-N bond formation, and a second electron transfer step to reduce a carbon-centered radical, rendering the overall process redox-neutral. A range of structurally diverse N-aryl heterocycles can be prepared in good to excellent yields under conditions significantly milder than those required by conventional aminium-based protocols.

A redox-neutral intermol. dicarbofunctionalization of styrenes e.g., (1-phenylethenyl)benzene with CO2 at atm. pressure and carbon-centered radicals such as CF3SO2Na, CHF2SO2Na, ArCH2BF3K (Ar = Ph, 4-(CH3)3CC6H4), ROC(O)2OCs (R = (CH3)3C, 1-methylcyclohexyl) to afford phenylacetic acids e.g., I was described. This mild protocol results in multiple C-C bond-forming reactions from simple precursors in the absence of stoichiometric reductants, thus exploiting a previously unrecognized opportunity that complements existing catalytic carboxylation events.

We report a combined exptl. and theor. study on cationic Ir(III) complexes for OLED applications and describe a strategy to tune the phosphorescence wavelength and to enhance the emission quantum yields for this class of compounds This is achieved by modulating the electronic structure and the excited states of the complexes by selective ligand functionalization. In particular, we report the synthesis, electrochem. characterization, and photophys. properties of a new cationic Ir(III) complex, [Ir(2,4-difluorophenylpyridine)2(4,4′-dimethylamino-2,2′-bipyridine)](PF6) (N969), and compare the results with those reported for the analogous [Ir(2-phenylpyridine)2(4,4′-dimethylamino-2,2′-bipyridine)](PF6) (N926) and for the prototype [Ir(2-phenylpyridine)2(4,4′-tert-butyl-2,2′-bipyridine)](PF6) complex, hereafter labeled N925. The three complexes allow us to explore the (C N) and (N N) ligand functionalization: considering N925 as a reference, we investigate in N926 the effect of electron-releasing substituents on the bipyridine ligand, while in N969, we investigate the combined effect of electron-releasing substituents on the bipyridine ligand and the effect of electron-withdrawing substituents on the phenylpyridine ligands. For N969 we obtain blue-green emission at 463 nm with unprecedented high quantum yield of 85% in acetonitrile solution at room temperature To gain insight into the factors responsible for the emission color change and the different quantum yields, we perform DFT and TDDFT calculations on the ground and excited states of the three complexes, characterizing the excited-state geometries and including solvation effects on the calculation of the excited states. This computational procedure allows us to provide a detailed assignment of the excited states involved in the absorption and emission processes and to rationalize the factors determining the efficiency of radiative and nonradiative deactivation pathways in the investigated complexes. This work represents an example of electronic structure-driven tuning of the excited-state properties, thus opening the way to a combined theor. and exptl. strategy for the design of new iridium(III) phosphors with specific target characteristics.

Despite allene derivatives have been always regarded as a radical accepter in traditional radical chem. for decades, the reactivity of allene derivatives under excited state in radical chem. was rarely explored. Herein, we report an example to engage triplet-excited state of allene moiety as hydrogen-atom-transfer (HAT) partner in the activation of remote sp3 C-H bond via visible-light irradiation under mild reaction conditions with broad substrate scope and good functional-group tolerance. The reaction mechanism involving the generation of triplet excited state of allene derivative and the subsequent HAT process was supported by deuterium labeling, kinetic anal. experiments and DFT calculations

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 676525-77-2, is researched, Molecular C40H40F6IrN4P, about Quantum Dot/Light-Emitting Electrochemical Cell Hybrid Device and Mechanism of Its Operation, the main research direction is quantum dot light emitting electrochem cell hybrid device; Förster resonant energy transfer; LEC; electron injection; hybrid device; iTMC; light-emitting electrochemical cell; quantum dots.Computed Properties of C40H40F6IrN4P.

A new type of light-emitting hybrid device based on colloidal quantum dots (QDs) and an ionic transition metal complex (iTMC) light-emitting electrochem. cell (LEC) is introduced. The developed hybrid devices show light emission from both active layers, which are combined in a stacked geometry. Time-resolved photoluminescence experiments indicate that the emission is controlled by direct charge injection into both the iTMC and the QD layer. The turn-on time (time to reach 1 cd/m2) at constant voltage operation is significantly reduced from 8 min in the case of the reference LEC down to subsecond in the case of the hybrid device. Furthermore, luminance and efficiency of the hybrid device are enhanced compared to reference LEC directly after device turn-on by a factor of 400 and 650, resp. We attribute these improvements to an increased electron injection efficiency into the iTMC directly after device turn-on.
