So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Martinez-Sarti, Laura; Pertegas, Antonio; Monrabal-Capilla, Maria; Gilshteyn, Evgenia; Varjos, Ilkka; Kauppinen, Esko I.; Nasibulin, Albert G.; Sessolo, Michele; Bolink, Henk J. researched the compound: [Ir(dtbbpy)(ppy)2]PF6( cas:676525-77-2 ).Application In Synthesis of [Ir(dtbbpy)(ppy)2]PF6.They published the article 《Flexible light-emitting electrochemical cells with single-walled carbon nanotube anodes》 about this compound( cas:676525-77-2 ) in Organic Electronics. Keywords: single walled carbon nanotube anode light emitting electrochem cell. We’ll tell you more about this compound (cas:676525-77-2).

In this work, we demonstrate flexible solution processed light emitting electrochem. cells (LECs) which use single-walled carbon nanotubes (SWCNTs) films as the substrate. The SWCNTs were synthesized by an integrated aerosol method and dry-transferred on the plastic substrates at room temperature The addition of a screen printed poly (3,4-ethylene dioxythiophene) doped with poly (styrene sulfonate) (PEDOT:PSS) film onto the nanostructured electrode further homogenizes the surface and enlarges the work function, enhancing the hole injection into the active layer. By using an efficient phosphorescent ionic transition metal complex (iTMC) as the active material, efficacies up to 9 cd/A have been obtained. These values are among the highest reported so far for light-emitting diodes employing CNTs as transparent electrode.

The photoredox-catalyzed aroyloxylation of aromatic C-H bonds with N-aroyloxylutidinium salts giving phenol derivatives has been developed. The present peroxide-free photocatalytic system is a convenient protocol for the generation of O-centered aroyloxy radicals under mild reaction conditions. In particular, N-3,5-bis(trifluoromethyl)phenylcarbonyloxylutidinium salt serves as an efficient aroyloxylating reagent by the action of Ir photocatalysts.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Selective Radical-Radical Cross-Couplings: Design of a Formal β-Mannich Reaction, the main research direction is radical cross coupling cyclic ketone imine photoredox catalysis organocatalysis.Category: copper-catalyst.

A direct β-coupling of cyclic ketones with imines has been accomplished via the synergistic combination of photoredox catalysis and organocatalysis. Transient β-enaminyl radicals derived from ketones via enamine and oxidative photoredox catalysis readily combine with persistent α-amino radicals in a highly selective hetero radical-radical coupling. This novel pathway to γ-aminoketones is predicated upon the use of DABCO as both a base and an electron transfer agent. This protocol also formally allows for the direct synthesis of β-Mannich products via a chemoselective three-component coupling of aryl aldehydes, amines, and ketones.

Author is Wang, Hao; Gao, Yuzhen; Zhou, Chunlin; Li, Gang.

The first example of visible-light-driven reductive carboarylation of styrenes with CO2 and aryl halides in a regioselective manner has been achieved. A broad range of aryl iodides and bromides were compatible with this reaction. Moreover, pyridyl halides, alkyl halides, and even aryl chlorides were also viable with this method. These findings may stimulate the exploration of novel visible-light-driven Meerwein arylation-addition reactions with user-friendly aryl halides as the radical sources and the photocatalytic utilization of CO2. Thus, e.g., reaction of 1,1-diphenylethylene with PhI and CO2 under blue light in presence of [Ir(ppy)2(dtbbpy)]PF6 photocatalyst and hydrogen atom transfer catalyst DABCO with HCO2K as terminal reductant and K2CO3 as base in DMSO followed by methylation afforded I (82%, 78% isolated).

Author is Koike, Takashi; Akita, Munetaka.

Trifluoromethyl (CF3) and difluoromethyl (CF2H) groups are versatile structural motifs, especially in the fields of pharmaceuticals and agrochems. Thus, the development of new protocols for tri- and difluoromethylation of various skeletons has become a vital subject to be studied in the field of synthetic organic chem. For the past decades, a variety of fluoromethylating reagents have been developed. In particular, bench-stable and easy-to-use electrophilic fluoromethylating reagents such as the Umemoto, Yagupolskii-Umemoto, Togni, and Hu reagents serve as excellent fluoromethyl sources for ionic and carbenoid reactions. Importantly, the action of catalysis has become a promising strategy for developing new fluoromethylations.For the past several years, photoredox catalysis has emerged as a useful tool for radical reactions through visible-light-induced single-electron-transfer (SET) processes. Commonly used photocatalysts such as [Ru(bpy)3]2+ and fac-[Ir(ppy)3] (bpy = 2,2′-bipyridine; ppy = 2-pyridylphenyl) have potential as one-electron reductants strong enough to reduce those fluoromethylating reagents, resulting in facile generation of the corresponding fluoromethyl radicals. Therefore, if we can design proper reaction systems, efficient and selective radical fluoromethylation would proceed without any sacrificial redox agents, i.e., via a redox-neutral process under mild reaction conditions: irradiation with visible light, including sunlight, below room temperature It should be noted that examples of catalytic fluoromethylation of compounds with carbon-carbon multiple bonds have been limited until recent years.In this Account, we will focus on our recent research on photoredox-catalyzed fluoromethylation of carbon-carbon multiple bonds. First, choices of the photocatalyst and the fluoromethylating reagent and the basic concept involving a redox-neutral oxidative quenching cycle are explained. Then photocatalytic trifluoromethylation of olefins is discussed mainly. Trifluoromethylative difunctionalization reactions, i.e., simultaneous introduction of the CF3 group and a different functional group across carbon-carbon double bonds, are in the middle of the discussion. Oxy-, amino-, and ketotrifluoromethylation allow us to synthesize various organofluorine compounds bearing C(sp3)-CF3 bonds. In addition, the synthesis of valuable trifluoromethylated alkenes is also viable when the olefins have an appropriate leaving group or undergo deprotonation. The present reaction system features high functional group compatibility and high regioselectivity. Furthermore, future prospects, especially trifluoromethylative difunctionalization of alkynes and difluoromethylation of alkenes, are also discussed.
