Nucleophilic aromatic substitution is a classical tool for arylation of heteroatom nucleophiles, and recent developments in hypervalent iodine-mediated arylations allow a wide scope of substrates. The benefits of these strategies were combined to enable an efficient and transition-metal-free difunctionalization of N- and O-nucleophiles with two structurally different aryl groups and to provide di- and triarylamines and diaryl ethers in one single step (>100 examples). The core of this strategy is the unique reactivity discovered with specifically designed fluorinated diaryliodonium salts, which unveils novel reaction pathways in hypervalent iodine chem. The methodol. is suitable for diarylation of aliphatic amines, anilines, ammonia and even water. It tolerates a wide variety of functional and protecting groups, with the retained iodine substituent easily accessible for derivatization of the products. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Formula: C19H22F3IO3S).

Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Formula: C19H22F3IO3S

Palladium-catalyzed direct β-arylation of ketones with diaryliodonium salts: a stoichiometric heavy metal-free and user-friendly approach was written by Huang, Zhongxing;Sam, Quynh P.;Dong, Guangbin. And the article was included in Chemical Science in 2015.Quality Control of Mesityl(p-tolyl)iodonium trifluoromethanesulfonate The following contents are mentioned in the article:

A new protocol for the Pd-catalyzed β-arylation of ketones such as cyclohexanone, cyclopentanone, cycloheptanone, etc. without stoichiometric heavy metals has been reported. Widely accessible mesitylaryliodonium salts I (Ar = C₆H₅, naphth-1-yl, 2,5-dimethylthiophen-3-yl, biphenyl-4-yl, etc.) are used as both the oxidant and aryl source. This tandem redox catalysis merges ketone dehydrogenation and conjugate addition without an addnl. oxidant or reductant. This transformation features the use of a unique bis-N-tosylsulfilimine ligand and the combination of potassium trifluoroacetate/trifluoroacetic acid to maintain an appropriate acidity of the reaction medium. The reaction tolerates both air and moisture, and shows a broad substrate scope. Kinetics studies, along with filtration and poisoning tests, support the involvement of palladium nanoparticles in the catalysis. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Quality Control of Mesityl(p-tolyl)iodonium trifluoromethanesulfonate).

And the article was included in Tetrahedron Letters in 2013.COA of Formula: C12H8INO3 The following contents are mentioned in the article:

An efficient superparamagnetic Pd-ZnFe₂O₄ solid catalyst has been synthesized by loading Pd(0) species on zinc ferrite nanoparticles. Sonogashira cross couplings between terminal alkynes and aryl halides were achieved in the absence of any Cu co-catalyst. A Heck-Matsuda coupling reaction of structurally different aryldiazonium tetrafluoroborate substrates was preceded at 40 °C in water. Cyanation of aryl halides was successfully done using K₄[Fe(CN)₆] as the cyanide source over Pd-ZnFe₂O₄. The catalyst was also employed for Ullmann type cross coupling reactions. Excellent yield of the products, reusability, and uncomplicated work-up make this catalyst efficient for C-C and C-O coupling reactions. Good yield of products, easy separation, and negligible leaching of Pd from the catalyst surface confirm the true heterogeneity in these catalytic reactions.

Herein we report the identification of a novel class of HDAC6 and HDAC8 selective inhibitors through a unique chem. and phenotypic screening strategy. Tetrahydroisoquinoline 12 was identified as a potent HDAC6 and HDAC8 dual inhibitor from a focused library through cellular tubulin acetylation and p21 induction screening assays. Scaffold hopping from 12 led to the discovery of an aminotetralin class of HDAC inhibitors. In particular, the 3-R stereoisomer 32 showed highly potent inhibition against HDAC6 and HDAC8 with IC₅₀ values of 50 and 80 nM, resp. Treatment of neuroblastoma BE(2)C cells with 32 resulted in elevated levels of acetylated tubulin, TrkA, and neurite outgrowth with only marginal effects on p21 induction and histone H3 acetylation. Consistent with its weak enzymic inhibition of HDAC1, 32 showed significantly less cytotoxicity than SAHA and moderately inhibited the growth of myeloma NCI-H929 and OPM-2 cells. This study involved multiple reactions and reactants, such as 2-Chloro-4-iodobenzonitrile (cas: 371764-70-4Electric Literature of C7H3ClIN).

This protocol provides a step-economic and highly efficient pathway to 1-aryl, 1,3-diaryl, 1,7-diaryl and 1,3,7-triaryl spirobifluorenes from readily available starting materials. The applications of multi-aryl spirobifluorenes as pure hydrocarbon (PHC) hosts for red, green, and blue (RGB) phosphorescent organic light-emitting diodes (PhOLEDs) were explored. Due to high triplet energies, 1,3-diaryl spirobifluorenes exhibit the potential as the host material of blue PhOLEDs. 1,7-Diaryl spirobifluorene can serve as the host of green PhOLEDs. 1,3,7-Triaryl spirobifluorene is a high-performance host for red PhOLEDs, which exhibits a high external quantum efficiency (EQE) up to 27.3%. This work not only exemplifies the great potential of multi-aryl spirobifluorenes as PHC hosts, but also offers a new approach for the synthesis of these PHC hosts.

Iridium(III)-Catalyzed Direct Arylation of C-H Bonds with Diaryliodonium Salts was written by Gao, Pan;Guo, Wei;Xue, Jingjing;Zhao, Yue;Yuan, Yu;Xia, Yuanzhi;Shi, Zhuangzhi. And the article was included in Journal of the American Chemical Society in 2015.Synthetic Route of C17H18F3IO3S The following contents are mentioned in the article:

By developing a new Ir(III)-catalyzed C-C cross-coupling, a versatile method for direct arylation of sp² and sp³ C-H bonds in ketoximes, nitrogen-containing heterocycles, various arenes, and olefins has been established. The key to this arylation depends on the appropriate choice of catalyst and the use of diaryliodonium triflate salts as the coupling partners. This transformation has good functional group compatibility and can serve as a powerful synthetic tool for late-stage C-H arylation of complex compounds Mechanistic studies by d. functional theory calculations suggested that the sp³ C-H activation was realized by a triflate-involved concerted metalation-deprotonation process, and the following oxidation of Ir(III) to Ir(V) is the most favorable when a bistriflimide is contained in the diaryliodonium salt. Calculations indicated that both steps are enabled by initial anion exchange between the reactant complexes. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Synthetic Route of C17H18F3IO3S).
