The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Enantioselective Allylic Alkylation with 4-Alkyl-1,4-dihydro-pyridines Enabled by Photoredox/Palladium Cocatalysis》.

Through the article, more information about this compound (cas:676525-77-2) is conveyed.

Highly regio- and enantioselective allylic alkylation has been achieved enabled by the merger of photoredox and palladium catalysis. In this dual catalytic process, alkyl radicals generated from 4-alkyl-1,4-dihydropyridines act as the coupling partners of the π-allyl palladium complexes [e.g., irradiation of racemic allylic acetate I and 4-benzyl Hantzsch ester in presence of Ir(ppy)2(dtbbpy)PF6 photocatalyst and Pd2(dba)3/(R)-GARPHOS in MeCN afforded II (76% GC yield, 72% isolated yield, B/L > 95:5, 94% ee)]. The generality of this method has been illustrated through the reaction of a variety of allyl esters with 4-alkyl-1,4-dihydropyridines. This mechanistically novel strategy expands the scope of the traditional Pd-catalyzed asym. allylic alkylation reaction and serves as its alternative and potential complement.

Related Products of 676525-77-2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Degradation of Ir(ppy)2(dtb-bpy)PF6 iTMC OLEDs. Author is Goldberg, Velda; Kaplan, Michael D.; Soltzberg, Leonard; Armira, Dolly; Bigelow, Megan; Bitzas, Stephanie; Brady, Rachel; Browne, Shannon; Dichiaro, Bianca; Foley, Heather; Hutchinson, Lauren; Inglis, Alison; Kawamoto, Nicole; McLaughlin, Amanda; Millett, Caitlin; Nasri, Hanah; Newsky, Sarah; Pham, Tram; Saikin, Cassandra; Scharpf, Mary; Trieu, Melissa; Malliaras, George G.; Bernhard, Stefan.

Simplicity of construction and operation are advantages of iTMC (ionic transition metal complex) OLEDs (organic light emitting diodes) compared with multi-layer OLED devices. Lifetimes do not compare favorably with the best multi-layer devices. It was previously shown for Ru(bpy)3(PF6)2 based iTMC OLEDs that elec. drive produces emission-quenching dimers of the active species. Evidence is reported that a chem. process may be implicated in degradation of devices based on Ir(ppy)2(dtb-bpy)PF6 albeit by a different mechanism. Apparently degradation of operating devices made with this Ir-based complex is related to current-induced heating of the organic layer, resulting in loss of the dtb-bpy ligand. (The dtb-bpy ligand is labile compared with the cyclometallated ppy ligands.). Morphol. changes observed in elec. driven Ir(ppy)2(dtb-bpy)PF6 OLEDs provide evidence of substantial heating during device operation. Evidence from UV-visible spectra in the presence of an elec. field as well as MALDI-TOF mass spectra of the OLED materials before and after elec. drive add support for this model of the degradation process.

Visible light photoredox catalyzed inter- and intramol. C-H functionalization reactions of tertiary amines have been developed. Oxygen was found to act as chem. switch to trigger two different reaction pathways and to obtain two different types of products from the same starting material. In the absence of oxygen, the intermol. addition of N,N-dimethylanilines to electron-deficient alkenes provided γ-amino nitriles in good to high yields. In the presence of oxygen, a radical addition/cyclization reaction occurred which resulted in the formation of tetrahydroquinoline derivatives in good yields under mild reaction conditions. The intramol. version of the radical addition led to the unexpected formation of indole-3-carboxaldehyde derivatives Mechanistic investigations of this reaction cascade uncovered a new photoredox catalyzed C-C bond cleavage reaction.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Visible-Light-Triggered Directly Reductive Arylation of Carbonyl/Iminyl Derivatives through Photocatalytic PCET, published in 2017-07-21, which mentions a compound: 676525-77-2, mainly applied to nitrile carbonyl reductive arylation imine photocatalyst radical; secondary alc amine preparation, Recommanded Product: [Ir(dtbbpy)(ppy)2]PF6.

The first visible-light-mediated radical-radical cross-coupling strategy that enables the direct arylation of carbonyl/iminyl derivatives in the presence of Et3N has been realized. Such an atom-economical protocol furnishes a broad scope of arylation products such as secondary/tertiary alcs. and amines via a PCET process that facilitates the challenging reduction of C=X (X = O, N). Mechanistic investigation indicates two photocatalytic redox cycles were involved in the process, and Et3N was proved to serve as a dual reductant and proton donor. Moreover, the isolated byproducts and controlled experiments could be considered as powerful supporting evidence for our hypothesis.

Author is Sun, Liangfeng; Galan, Armand; Ladouceur, Sebastien; Slinker, Jason D.; Zysman-Colman, Eli.

We explore the photophys., electrochem., and electroluminescent properties of the ionic transition metal complex [(ppy)2Ir(bpy*)](PF6) where ppyH is 2-phenylpyridine and bpy* is 5,5′-diaryl-2,2′-bipyridine. Single layer devices of the structure ITO/[(ppy)2Ir(bpy*)](PF6)/Au exhibited high stability, with half-lives on the order of 100 h at a bias of -4 V. Long lifetimes are achieved through the bulky nature of the aryl substituents, which serves to limit chromophore-chromophore self-quenching, and 5,5′ positioning of these bulky groups is clearly advantageous for device performance.

Application of 676525-77-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Two new Cu-based borate catalysts with cubic supramolecular cages for efficient catalytic hydrogen evolution. Author is Liu, Wen-Fang; Qiu, Qi-Ming; Zhang, Mo; Su, Zhao-Min; An, Qingqing; Lv, Hongjin; Jia, Zhiyu; Yang, Guo-Yu.

Focusing on renewable energy, efficient, robust and low cost water reduction catalysts (WRCs) are developed. Two new Cu-based borate catalysts, namely H2Na2K2[(μ4-O)Cu4@B20O32(OH)8]·21H2O (1) and H2Rb1.6K2.4[(μ4-O)Cu4@B20O32 (OH)8]·15H2O (2), with cubic supramol. cages were synthesized under a hydrothermal condition. Moreover, new copper complexes were applied as water reduction catalysts (WRCs) in the presence of [Ir(ppy)2(dtbbpy)][PF6] as photosensitizer and triethanolamine (TEOA) as the sacrificial electron donor. Nevertheless, the main active place is attributed to the center of Borates [(μ4-O)Cu4@B20O32(OH)8], and the at. radius of the counter cation would be the critical factor of the photocatalytic activity. Increasing the at. radius from the Na atom to the Rb atom, causes the photocatalytic activity to decrease efficiently. The exptl. results match well with the d. functional theory (DFT) conclusion. the research not only enriches the Cu-based borate chem., but also investigates the photocatalytic activity of Cu-based borates. This would guide us through the borate synthesis and to develop their applications toward energy and the environment.
