Anti-Markovnikov Hydroamination of Unactivated Alkenes with Primary Alkyl Amines

We report here a photocatalytic method for the intermolecular anti-Markovnikov hydroamination of unactivated olefins with primary alkyl amines to selectively furnish secondary amine products. These reactions proceed through aminium radical cation (ARC) intermediates and occur at room temperature under visible light irradiation in the presence of an iridium photocatalyst and an aryl thiol hydrogen atom donor. Despite the presence of excess olefin, high selectivities are observed for secondary over tertiary amine products, even though the secondary amines are established substrates for ARC-based olefin amination under similar conditions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: Methanesulfonato(2-dicyclohexylphosphino-2′,4′,6′-tri-i-propyl-1,1′-biphenyl)(2′-amino-1,1′-biphenyl-2-yl)palladium(II), If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1445085-55-1, in my other articles.

Synthesis of polyarylated methanes through cross-coupling of tricarbonylchromium-activated benzyllithiums

Support group: Coordinated to the tricarbonylchromium fragment, a typically unstable benzylic organolithium can participate directly in cross-coupling reactions with aryl bromides to form polyarylated methane derivatives (see scheme).

Enantioselective functionalization of radical intermediates in redox catalysis: Copper-catalyzed asymmetric oxytrifluoromethylation of alkenes

Something radical: An efficient enantioselective oxytrifluoromethylation of alkenes has been developed using a copper catalyst system. Mechanistic studies are consistent with a metal-catalyzed redox radical addition mechanism in which a C-O bond is formed by the copper-mediated enantioselective trapping of a prochiral alkyl radical intermediate derived from the initial trifluoromethyl radical addition.

Palladium-catalyzed cross-coupling reactions of dithienosilole with indium reagents: Synthesis and characterization of dithienosilole derivatives and their application to organic light-emitting diodes

Three dithienosilole (DTS) derivatives bearing naphthyl segments, 5,5?-dinaphthyl-1,1-dimethyldithienosilol (1), 5,5?-dinaphthyl-1- methyl-1-phenyldithienosilole (2), and 5,5?-dinaphthyl-1,1- diphenyldithienosilol (3), are prepared through Pd(II)-catalyzed cross-coupling using an organoindium reagent as a nucleophile. The molecular structure of 3 is confirmed by single-crystal X-ray analysis. In addition, thermal, photophysical, and electrochemical properties for all three compounds are systematically investigated. The introduction of naphthyl segments into the DTS framework leads to an excellent enhancement of thermal stability with relatively high glass transition (Tg: 87 C) and decomposition temperatures (T d: 320-380 C). A red shift in both absorption and emission is observed in the DTS series as the 1,1-substituents on the ring silicon atom become more electronegative. On the basis of absorption spectra and DFT/TDDFT calculations, intense green photoluminescence observed for all compounds can be attributed to the effective pi-pi* transition of the DTS and naphthyl group with a small contribution of the sigma* orbital of the exocyclic Si-C bond. The electron-transporting properties of 1, 2, and 3 were evaluated by the performance of organic light-emitting diodes (OLEDs), comprising 4,4?,4??-tris(N-(2-naphthyl)-N-phenylamino)triphenylamine (2-TNATA) as hole-injection layer, 4,4?-bis(N-phenyl-1-naphthylamino) biphenyl (NPB) as hole-transport layer, 10-(2-benzothiazolyl)-1,1,7,7- tetramethyl-2,3,6,7-tetrahydro-1H,5H,11H-benzo[l]pyrano[678-ij] quinolizin-11-one(C545T)/tris(8-quinolinato)aluminum (Alq3) as emitting layer, and the DTS series as electron-transporting layer, respectively. The device shows intense green emission with a high efficiency of 8.0 cd/A at 1000 cd/m2.

Palladium-catalyzed heteroaryl thioethers synthesis overcoming palladium dithiolate resting states inertness: Practical road to sulfones and NH-sulfoximines

We provide efficient synthetic access to heteroaryl sulfones in two-steps using a simple palladium?1,1?-bis[(diphenyl)phosphanyl]ferrocene catalyst to form in high yields variously functionalized heteroaromatic thioethers. Pyridinyl-containing substrates can be subsequently selectively oxidized into sulfones and NH-sulfoximines by using very mild oxidation conditions with a high functional group tolerance. In the palladium-catalyzed C?S coupling of heteroaromatic thiols, reactivity limitation is attached with electron-deficient thiols. We show that this limitation can be resolved by the successful use of 2-bromoheteroarenes in the C?S coupling. We established herein that this choice of heteroaryl electrophilic reagent in palladium-catalyzed C?S bond formation allows overcoming palladium dithiolate out-of-cycle resting state inertness. This was illustrated in the stoichiometric reactivity study of the palladium dithiolate formed from 4-trifluoromethylbenzen-1-thiol ?isolated and characterized by multinuclear NMR and XRD? with both 2-chloropyridine and 2-bromopyridine.

Cyclometallated, bis-terdentate iridium complexes as linearly expandable cores for the construction of multimetallic assemblies

Cyclometallated iridium complexes comprised of two terdentate cyclometallating ligands, of the form [Ir(NCN)(NNC)]+, have been explored for the preparation of multimetallic systems by palladium-catalysed cross-coupling reactions. An NNC-coordinating ligand carrying a boronate ester group has been prepared and complexed to iridium to give a boronic acid appended complex of this type, 3. This complex has been subjected to cross-coupling with a bromo-substituted bis-terpyridyl iridium complex to give a dinuclear iridium compound 6, in which one of the two iridium centres is N6-coordinated and the other has an N4C2-coordination sphere. Meanwhile, a bromo-substituted complex 4 has been coupled with a boronic acid-appended ruthenium complex, to give a dinuclear heterometallic complex 8 that can be activated to a second coupling by in situ bromination, offering access to a linear Ir-Ir-Ru trimetallic assembly 11. The electrochemical and luminescence properties of these systems are investigated. In the case of 8 and 11, the behaviour can be rationalised in terms of a supramolecular description: efficient energy transfer occurs from the Ir terminus to the Ru. In contrast, for compound 6, an excited state with significant bridge character appears to play a key role in determining the emission properties. The Royal Society of Chemistry 2009.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 95464-05-4 is helpful to your research. Synthetic Route of 95464-05-4

Optimizing the conjugation between N,N0-dicarbazolyl-3, 5-benzene and triphenylphosphine oxide as bipolar hybrids for highly efficient blue and single emissive layer white phosphorescent OLEDs

Two bipolar host materials, mCPpPO and mCPmPO have been synthesized by Ni(II)/Zncatalyzed cross-coupling of diphenylphosphine oxide and corresponding aryl bromide. The photophysical properties, HOMO/LUMO orbital distribution and triplet levels of these host materials are investigated and optimized by tuning the linking modes between electron acceptor triphenylphosphine oxide and electron donor N,N0-dicarbazolyl-3,5-benzene (mCP). When mCP is linked to the meta-position of benzene of triphenylphosphine oxide, the hybrid (mCPmPO) shows much higher steric hinderance than the para-position linked analogue (mCPpPO) so that it possesses a higher triplet energy. Equipped with the bipolar transport properties, mCPmPO-based blue PhOLED doped FIrpic shows a maximum current efficiency (etac,max) of 40.0 cd/A, a maximum power efficiency (etap,max) of 39.7 lm/W, corresponding the maximum external quantum efficiency (etaEQE,max) of 20.3%, and the current efficiency still maintain to 34.8 cd/A even at 1000 cd/m2. Based on the optimized triplet energy level, the single emission layer white PhOLED hosted by mCPmPO shows etac,max, etap,max and etaEQE,max of 46.9 cd/A, 39.7 lm/W and 17.6%, respectively.
