Fischer, Oliver published the artcileShifted Selectivity in Protonation Enables the Mild Deuteration of Arenes Through Catalytic Amounts of Bronsted Acids in Deuterated Methanol, Product Details of C8H10O2, the main research area is Bronsted acid catalyzed deuteration arene deuterated methanol.

Taking advantage of the “”differentiating effect”” of the solvent methanol, deuterations of electron-rich aromatic systems can be carried out under mild acid catalysis and thus under far milder conditions than known so far. The exceptional functional group tolerance observed under the optimized conditions, which even includes highly acid-labile groups, results from a hitherto unexploited shifted selectivity in protonation, and enabled simple and straightforward access to complex deuterium-labeled compounds

Zhao, Haiwei published the artcileTwo Ligands Transfer from Ag to Pd: En Route to (SIPr)Pd(CF2H)(X) and Its Application in One-Pot C-H Borylation/Difluoromethylation, Computed Properties of 151-10-0, the main research area is fluoromethyl palladium imidazolinylidene complex preparation crystal structure fluoromethylation catalyst; crystal structure fluoromethyl palladium arylimidazolinylidene complex; mol structure fluoromethyl palladium arylimidazolinylidene complex; hetero arene borylation difluoromethylation palladium catalyst; fluoromethylated heteroarene preparation.

A process for the concurrent transfer of both the NHC ligand and difluoromethyl group from [(SIPr)Ag(CF2H)] to PdX2 (X = Cl, OAc and OPiv) for the preparation [(SIPr)Pd(CF2H)X] complexes is described. These complexes were air-stable and easily underwent transmetalation with aryl pinacol boronate/reductive elimination to generate ArCF2H in high yields. Based on this discovery, the 1st 1-pot C-H borylation and difluoromethylation for the preparation of difluoromethylated (hetero)arenes was developed.

Ding, Siyi published the artcileNNB-type tridentate boryl ligands enabling a highly active iridium catalyst for C-H borylation, Related Products of isoquinoline, the main research area is boryl ligand preparation iridium complex catalyst carbon hydrogen borylation; C–H borylation reaction; boryl ligand; iridium-catalyzed.

Boryl ligands play a very important role in catalysis because of their very high electron-donating property. NNB-type boryl anions were designed as tridentate ligands to promote aryl C-H borylation. In combination with [IrCl(COD)]2, they generate a highly active catalyst for a broad range of (hetero)arene substrates, including highly electron-rich and/or sterically hindered ones. This work provides a new NNB-type tridentate boryl ligand to support homogeneous organometallic catalysis.

Pei, Xiaocong published the artcileSterically controlled C-H/C-H homocoupling of arenes via C-H borylation, Category: isoquinoline, the main research area is biaryl preparation regioselective; arene borylation homocoupling iridium copper catalyst.

A mild one-pot protocol for the synthesis of biaryls R-R [R = 3-chloro-5-methylphenyl, 3-bromo-2-fluoro-5-(trifluoromethyl)phenyl, naphth-2-yl, etc.] by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes RH has been described. The regiochem. of the biaryls is sterically controlled as dictated by the C-H borylation step. The methodol. is also successfully extended to heteroarenes R1H (R1 = benzofuran-2-yl, 2-methylthiophen-5-yl, 3-chloropyridin-5-yl, etc.). Some of the products obtained by this approach are impossible to obtain via Ullmann or Suzuki coupling protocols. Finally, one-pot sequence describing C-H borylation/Cu-catalyzed homocoupling/Pd-catalyzed Suzuki coupling to obtain π-extended arene framework has been reported.

Fujita, Takeshi published the artcileAcid-mediated intermolecular C-F/C-H cross-coupling of 2-fluorobenzofurans with arenes: synthesis of 2-arylbenzofurans, Category: isoquinoline, the main research area is halobenzofuran arene acid promotor cross coupling reaction; aryl benzofuran preparation.

Transition-metal-free acid-promoted biaryl construction was achieved via intermol. C-F/C-H cross-coupling. By treating 2-fluorobenzofurans with arenes in the presence of AlCl3, 2-arylbenzofurans were obtained. This protocol was successfully applied to the short-step orthogonal synthesis of a bioactive 2-arylbenzofuran natural product, which allows independent transformations of C-F and C-Br bonds. Mechanistic studies indicated that α-fluorine-stabilized carbocations, generated via the protonation of 2-fluorobenzofurans, served as key intermediates. The Friedel-Crafts-type C-C bond formation between the α-fluorocarbocations and arenes, followed by hydrogen fluoride elimination, afforded 2-arylbenzofurans.

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.

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.
