Wright, Jay S. published the artcileSequential Ir/Cu-Mediated Method for the Meta-Selective C-H Radiofluorination of (Hetero)Arenes, Safety of 1,3-Dimethoxybenzene, the main research area is sequential iridium copper mediated regioselective radiofluorination arene heteroarene.

This article describes a sequential Ir/Cu-mediated process for the meta-selective C-H radiofluorination of (hetero)arene substrates. In the first step, Ir-catalyzed C(sp2)-H borylation affords (hetero)aryl pinacolboronate (BPin) esters. The intermediate organoboronates are then directly subjected to copper-mediated radiofluorination with [18F]tetrabutylammonium fluoride to afford fluorine-18 labeled (hetero)arenes in high radiochem. yield and radiochem. purity. This entire process is performed on a bench top without Schlenk or glove box techniques and circumvents the need to isolate (hetero)aryl boronate esters. The reaction was automated on a TracerLab FXFN module with 1,3-dimethoxybenzene and a meta-tyrosine derivative The products, [18F]1-fluoro-3,5-dimethoxybenzene and an 18F-labeled meta-tyrosine derivative, were obtained in 37 ± 5% isolated radiochem. yield and >99% radiochem. purity and 25% isolated radiochem. yield and 99% radiochem. purity, and 0.52 Ci/μmol (19.24 GBq/μmol) molar activity (Am), resp.

Saikia, Sudakhina published the artcileRegioselective Friedel-Crafts Acylation Reaction Using Single Crystalline and Ultrathin Nanosheet Assembly of Scrutinyite-SnO2, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is aryl ketone preparation regioselective solventless; arene acid chloride Friedel Crafts acylation tin oxide catalyst.

In this work, a facile and general approach for the synthesis of single crystalline and ultrathin 2D nanosheets assembly of scrutinyite-SnO2 through a simple solvothermal method has been described. The structural and compositional characterization using X-ray diffraction (Rietveld refinement anal.), high-resolution transmission electron microscopy, at. force microscopy, XPS, and so on reveal that the as-synthesized 2D nanosheets are ultrathin and single crystallized in the scrutinyite-SnO2 phase with high purity. The ultrathin SnO2 nanosheets show predominant growth in the [011] direction on the main surface having a thickness of ca. 1.3 nm. The SnO2 nanosheets are further employed for the regioselective Friedel-Crafts acylation to synthesize aromatic ketones RC(O)R1 (R = C6H5, 4-CH3C6H4, 2-thienyl, etc.; R1 = Me, Ph) that have potential significance in chem. industry as synthetic intermediates of pharmaceuticals and fine chems. A series of aromatic substrates acylated over the SnO2 nanosheets have afforded the corresponding aromatic ketones with up to 92% yield under solvent-free conditions. Comprehensive catalytic investigations display the SnO2 nanosheet assembly as a better catalytic material compared to the heterogeneous metal oxide catalysts used so far in the view of its activity and reusability in solvent-free reaction conditions.

Wei, Bin published the artcileElectrochemical radical C(sp3)-H arylation of xanthenes with electron-rich arenes, Safety of 1,3-Dimethoxybenzene, the main research area is aryl xanthene preparation green chem; xanthene arene electrochem radical arylation.

An efficient electrochem. C(sp3)-H arylation of xanthenes, e.g., 12H-benzo[a]xanthene with arenes ArH (Ar = 4-(dimethylamino)phenyl, 1-phenylpyrrolidine, 1-benzofuran, etc.) proceeds via a radical pathway. A series of 9-aryl-9H-xanthenes, e.g., I were observed to have been produced in the presence of a carbon anode, platinum cathode, MsOH and NHPI at room temperature from available N,N-disubstituted anilines, heterocyclic aromatic hydrocarbons and anisoles. Notably, the significant advantages of this transformation were found to include mild transition-metal-catalyst-free reaction conditions, good functional group tolerance, and a highly atom- and step-economic strategy.

Ding, Wei published the artcileSite-selective aromatic C-H λ3-iodanation with a cyclic iodine(III) electrophile in solution and solid phases, SDS of cas: 151-10-0, the main research area is arylbenziodoxole site selective preparation; arene benziodoxole triflate site selective aromatic iodanation.

An efficient and site-selective aromatic C-H λ3-iodanation reaction was achieved using benziodoxole triflate (BXT) as an electrophile under room temperature conditions. The reaction tolerated a variety of electron-rich arenes and heteroarenes to afford the corresponding arylbenziodoxoles I [R = 4-OMeC6H4, 2,4-di-MeC6H3, 2-thienyl, etc.] in moderate to good yields. The reaction could also be performed mechanochem. by grinding a mixture of solid arenes and BXT under solvent-free conditions. The arylbenziodoxoles could be used for various C-C and C-heteroatom bond formations and are also amenable to further modification by electrophilic halogenation. DFT calculations suggested that the present reaction proceeded via a concerted λ3-iodanation-deprotonation transition state, where the triflate anion acts as an internal base.

The confinement of a catalytic site is an efficient strategy to control a reaction and modulate its selectivity. In the present work, a new class of structurally simple and easily accessible bulky tri-(ortho-biaryl)phosphine ligands were accessed, and their gold(I) complexes [LAuX] [L = [2-(RC6H4)C6H4]3P, where R = 3-tBu, 3-Bu, 4-tBu, 4-C5H11; L = [2-(2-naphthyl)phenyl]3P; X = Cl, NTf2, NCMe] were prepared Their X-ray diffraction anal. and the comparative evaluation of their VBur% and G steric parameters against a series of gold complexes commonly employed in catalysis demonstrated their confined nature.
