The synthesis and properties of new polyimides (PIs) derived from 4,4′-bis(p-aminophenoxy)triphenylamine (APT) and N,N-bis[4-(4′-aminophenoxy)phenyl]aminopyrene (APPA) for memory device application is reported. The starting monomers were prepared from 4-iodophenol and 4-fluoronitrobenzene via etherification (giving 4-(4′-nitrophenoxy)iodobenzene) followed by amination with aniline or aminopyrene and final reduction of terminal nitro-group. Polyimides were synthesized by polycondensation of each monomer with hexafluoroisopropylidene-2,2-bis(phthalic anhydride) in dimethylacetamide. All PIs had electron-rich arylamine moieties combining flexible phenyl-ether linkages which provide polymers electron-donating properties to reduce driving voltage in a memory device. The PIs exhibited high thermal properties such as 10% weight loss temperature >500° and glass transition temperatures >250°. The effects of structure on the thermal, optical, and electrochem. properties of the PIs are described in detail. This study involved multiple reactions and reactants, such as 1-Iodo-4-(4-nitrophenoxy)benzene (cas: 21969-05-1Electric Literature of C12H8INO3).

1-Iodo-4-(4-nitrophenoxy)benzene (cas: 21969-05-1) belongs to iodide derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. Indole was synthesized in moderate yield via an o-naphthoquinone catalyzed tandem cross-coupling of substituted aniline and benzylamine under aerobic oxidation conditions.Electric Literature of C12H8INO3

Palladium-catalyzed redox cascade for direct β-arylation of ketones was written by Huang, Zhongxing;Dong, Guangbin. And the article was included in Tetrahedron in 2018.Electric Literature of C17H18F3IO3S The following contents are mentioned in the article:

A full article about the detailed design and development of two palladium-catalyzed redox cascade methods that enable direct β-arylation of ketones was reported. Palladium-catalyzed ketone dehydrogenation, aryl-X bond activation and conjugate addition were merged into a redox-neutral catalytic cycle. Non-metal-based aryl electrophiles were used as both the oxidant and the aryl source. The β-arylation with aryl iodides was achieved site-selectively with Pd(TFA)₂/P(i-Pr)₃ as the precatalyst and AgTFA as the iodide scavenger. Both cyclic and linear ketones were reacted to give β-aryl ketones with excellent functional group tolerance. The β-arylation with diaryliodonium salts was realized without stoichiometric heavy metal additives, and proved to be redox-neutral. A wider substrate scope regarding aryl groups and ketones was obtained for the arylation with diaryliodonium salts, and the possible involvement of palladium nanoparticles as the active catalyst was examined and discussed. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Electric Literature of C17H18F3IO3S).

Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives.

And the article was included in Organic & Biomolecular Chemistry in 2018.Product Details of 371764-70-4 The following contents are mentioned in the article:

Bioorthogonal reactions have emerged as valuable tools for site-specific protein labeling and modification in vitro and in vivo. Hydrazone and oxime ligation has recently attracted considerable attention for wide applications in the conjugation of biomols. However, this kind of reaction has suffered from slow kinetics under physiol. conditions and toxicity or complications of the reaction system due to catalysts. The authors have developed an electron-deficient benzaldehyde reagent, which can be easily equipped with various types of bio-functional mols. for catalyst-free hydrazone ligation. The reagent can be equipped with not only small mols. such as fluorescence dyes or drugs, but also macromols. like PEG. These can be precisely ligated to the C-terminus of proteins by an efficient hydrazone reaction at neutral pH and room temperature The new reagent based catalyst-free hydrazone ligation provides a practical approach for the site specific modification of proteins. This study involved multiple reactions and reactants, such as 2-Chloro-4-iodobenzonitrile (cas: 371764-70-4Product Details of 371764-70-4).

Recyclable synthesis of mesityl iodonium(III) salts was written by Dohi, Toshifumi;Hayashi, Takumi;Ueda, Shohei;Shoji, Toshitaka;Komiyama, Keina;Takeuchi, Hitoshi;Kita, Yasuyuki. And the article was included in Tetrahedron in 2019.Electric Literature of C17H18F3IO3S The following contents are mentioned in the article:

An efficient protocol for C-H condensation of hypervalent iodine compounds with arenes in fluoroalcs. was applied to the recyclable preparation of mesityl iodonium(III) salts. The electrophilicities of [hydroxy(tosyloxy)iodo]mesitylene [MesI(OH)OTs] and iodomesitylene diacetate [MesI(OAc)₂] were suitably enhanced in 2,2,2-trifluoroethanol. A series of nucleophilic aromatic compounds reacted smoothly with MesI(OH)OTs and MesI(OAc)₂ or in-situ hypervalent iodine(III) species, generated from iodomesitylene, to provide the target mesityl iodonium(III) salts in good yields at room temperature with broad functional group tolerance. This C-H condensation strategy merits high para-regioselectivities during the diaryliodonium(III) salt formation, but the major limitation in the case of low-reactive aromatic substrates is byproduct formation resulting from the self-condensation of the nucleophilic mesitylene ring in MesI(OH)OTs and MesI(OAc)₂. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Electric Literature of C17H18F3IO3S).

Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives.

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.

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).
