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.

Alkyl and alkoxy arenes were successfully functionalized, affording C(sp2)-H borylated compounds It was unraveled that the well-defined abnormal N-heterocyclic carbene based Ni(II) complex breaks into Ni nanoparticles (Ni-NPs), which act as catalytically active species. A series of controlled reactions under stoichiometric conditions along with spectroscopic studies and single-crystal x-ray crystallog. study helped us to understand the formation of Ni-NPs along with formation of a boron(III) compound during this reaction.

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.

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

Rokade, Balaji V. published the artcileSynthesis of α-Aryl-Oxindoles by Friedel-Crafts Alkylation of Arenes, Related Products of isoquinoline, the main research area is arylindole preparation; isatin diethylphosphite arene phospho Brook rearrangement Friedel Crafts reaction.

Synthesis of α-aryl-oxindoles was reported from isatin via a two-step procedure involving a phospha-Brook rearrangement and a Friedel-Crafts alkylation in a one-pot procedure. The use of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as solvent significantly extended the reaction substrate scope to include relatively less electron rich arenes including benzene. This new alkylation method is fast, straightforward and allows for the direct introduction of the oxindole moiety onto a range of aromatic compounds including phenols. Addnl., the application of arylated products was shown in decarboxylative asym. allylation and protonation.

Kalaramna, Pratibha published the artcileTransition-Metal-Free HFIP-Mediated Organo Chalcogenylation of Arenes/Indoles with Thio-/Selenocyanates, Category: isoquinoline, the main research area is HFIP mediated chalcogenylation arene indole aryl chalcogenocyanate; chalcogenide synthesis.

We have developed a protocol for the synthesis of diaryl thio-/selenoethers by the reaction of aryl chalcogenocyanates with electron rich arenes/hetero arenes via HFIP promoted C-H activation. The reaction produces chalcogenides in good to excellent yields under mild conditions without the need of a transition metal as a catalyst. The HFIP-mediated reactions tolerated a wide range of functional groups and set the stage for the synthesis of diversely decorated chalcogenides. A mechanism involving activation of the C-H bond through hydrogen bonding is proposed.

Paul, Sanjay published the artcilePd(TFA)2-Catalyzed direct arylation of quinoxalinones with arenes, Name: 1,3-Dimethoxybenzene, the main research area is aryl quinoxalinone regioselective preparation; quinoxalinone arene cross coupling.

The direct C-3 arylation of quinoxalin-2-ones with arenes was achieved by a Pd(TFA)2-catalyzed cross-dehydrogenative coupling (CDC) reaction. A wide array of functionalities, including highly sensitive allyl- and benzyl group substituted quinoxalin-2(H)-ones I [R = Me, geranyl, Bn, 4-ClBn 4-MeBn; R1 = H, Me, F, Cl, Br, COOMe; R2 = H, Me, F, Cl, Br; R3 = Ph, 2-MeC6H4, 4-FC6H4, etc.], were readily assembled with arenes containing electron-donating and electron-withdrawing groups in this CDC reaction. Highly regioselective products were produced in good yields with stronger electron-donating groups than toluene and densely substituted arenes as coupling partners. This protocol represented an efficient technique to access various 3-arylbenzo[g]quinoxalinones II [R4 = Me, Bn; R5 = Ph, 4-ClC6H4, 4-OMeC6H4] and 2-aryl-4-methylpyrido[3,4-b]pyrazin-3(4H)-ones under mild conditions.

Indoles, pyrroles, thiophenes, a benzothiophene, a benzofuran, and arenes underwent metal-free regioselective trifluoromethylthiolation with trifluoromethyl sulfoxides RCH2S(:O)CF3 (R = Ph, EtO2C) mediated by triflic anhydride and diethylamine in acetonitrile or nitromethane to yield heteroaryl and aryl trifluoromethyl thioethers. An aryl(ethoxycarbonylmethyl)(trifluoromethyl)sulfonium triflate was isolated as a trifluoromethylthiolation intermediate and its structure determined by X-ray crystallog., supporting an interrupted Pummerer reaction mechanism for the trifluoromethylthiolation.

Jud, Wolfgang published the artcileCathodic C-H Trifluoromethylation of Arenes and Heteroarenes Enabled by an in Situ-Generated Triflyltriethylammonium Complex, Safety of 1,3-Dimethoxybenzene, the main research area is cathodic fluoromethylation arene heteroarene in situ triflyltriethylammonium complex.

While several trifluoromethylation reactions involving the electrochem. generation of CF3 radicals via anodic oxidation have been reported, the alternative cathodic, reductive radical generation has remained elusive. Herein, the first cathodic trifluoromethylation of arenes and heteroarenes is reported. The method is based on the electrochem. reduction of an unstable triflyltriethylammonium complex generated in situ from inexpensive triflyl chloride and triethylamine, which produces CF3 radicals that are trapped by the arenes on the cathode surface.
