Author is Condie, Allison G.; Gonzalez-Gomez, Jose C.; Stephenson, Corey R. J..

The authors report the application of visible-light photoredox catalysis for the formation of C-C bonds between tertiary N-arylamines and nitroalkanes via an oxidative aza-Henry reaction. In the presence of 1 mol % Ir(ppy)2(dtbbpy)PF6, efficient coupling of nitroalkanes with in situ-generated iminium ions provides the desired products in up to 96% yield. Mechanistic studies suggest that reductive quenching of the Ir3+ excited state by the tertiary amine leads to the ammonium radical cation, with subsequent catalyst turnover (Ir2+ → Ir3+) likely effected by atm. oxygen.

Author is Roldan-Carmona, Cristina; Akatsuka, Takeo; Sessolo, Michele; Watkins, Scott E.; Bolink, Henk J..

Light-emitting electrochem. cells (LECs) consists of a thin film of an ionic organic semiconductor sandwiched between two electrodes. Because of the large d. of ions, LECs are often reported to perform independently on the electrodes work function. Here the authors use metal oxides as charge injection layers and demonstrate that, although electroluminescence is observed independently of the electrodes used, the device performances are strongly dependent on the choice of the interface materials. Relying on metal oxide charge injection layers, such hybrid devices are of interest for real lighting applications and could pave the way for new efficient, stable, low-cost lighting sources.

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 Carboxylation of Aryl Triflates with CO2 Merging Palladium and Visible-Light-Photoredox Catalysts, published in 2019-06-21, which mentions a compound: 676525-77-2, mainly applied to aryl triflate carbon dioxide carboxylation iridium palladium visible light; arylcarboxylic acid preparation; iridium palladium carboxylation catalyst; visible light carboxylation promoter, Name: [Ir(dtbbpy)(ppy)2]PF6.

A visible-light-promoted, highly practical carboxylation of readily accessible aryl triflates at ambient temperature and a balloon pressure of CO2 by the combined use of palladium and photoredox Ir(III) catalysts, is reported. Strikingly, the stoichiometric metallic reductant is replaced by a nonmetallic amine reductant providing an environmentally benign carboxylation process. In addition, one-pot synthesis of a carboxylic acid directly from phenol and modification of estrone and concise synthesis of pharmaceutical drugs adapalene and bexarotene have been accomplished via late-stage carboxylation reaction. Furthermore, a parallel decarboxylation-carboxylation reaction has been demonstrated in an H-type closed vessel that is an interesting concept for the strategic sector. Spectroscopic and spectroelectrochem. studies indicated electron transfer from the Ir(III)/DIPEA combination to generate aryl carboxylate and Pd(0) for catalytic turnover.

Now I present to you an article called Visible-light-induced photocatalytic reductive transformations of organohalides, published in 2012, which mentions a compound: 676525-77-2, mainly applied to organohalide free radical photocatalytic cyclization hydrodehalogenation visible light iridium, SDS of cas: 676525-77-2.

The iridium-catalyzed reductive cyclization and hydrodehalogenation of organohalides induced by visible light is described. This work shows that a broad range of alkyl, alkenyl, and aryl halides, not limited to alkyl substrates with an activating group, are competent participants in these photocatalytic free-radical processes and furnish the products in excellent yield. It has also been demonstrated that a simple alteration in reaction conditions, such as changing light sources, can bring about significant rate acceleration. These findings establish the feasibility of using structurally diverse organohalides for various free-radical mediated reactions through a convenient and environmentally benign catalytic means that makes use of visible light.
