Tu, Guangliang published the artcileLigand-Promoted Nickel-Catalyzed para-Selective Carboxylation of Anisoles, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is anisole regioselective carboxylation bromoform radical nickel catalyst.

It has always been a challenge in free radical chem. to control site selectivity during the reaction of free radicals with aromatic rings. Herein, the site-selective carboxylation of anisoles through the direct reaction of the bromoform radical with a benzene ring at the para position under the assistance of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline with nickel(II) as the catalyst is reported. A wide variety of anisoles were compatible, leading to para-carboxylated products in moderate to good yields. A preliminary mechanistic study suggested that the Ni(II) complex coordinates with the methoxyl group of the aromatic ring, which may have increased the steric hindrance at the ortho and meta positions, while this weak interaction reduces the aromaticity of the aromatic ring, affording an activated Ph ring, thereby leading to highly para-selective carboxylation.

Kang, Qi-Kai published the artcileCatalytic SNAr Hydroxylation and Alkoxylation of Aryl Fluorides, Computed Properties of 151-10-0, the main research area is phenol preparation DFT mechanistic study; water aryl fluoride hydroxylation rhodium catalyst; ester preparation DFT mechanistic study; aryl fluoride alc alkoxylation rhodium catalyst; C−O bond formation; Meisenheimer-type intermediate; rhodium; η6-coordination.

A reliable method for accessing phenols ArOH (Ar = C6H5, 4-CH3OC6H4, 9H-fluoren-2-yl, etc.) and Ph alkyl ethers Ar1OR (Ar1 = 4-CH3C6H4, 9H-fluoren-2-yl, 1-methyl-2-oxo-2,3-dihydro-1H-indol-5-yl, etc.; R = Me, cyclohexylmethyl, oxan-4-yl, etc.) via catalytic SnAr reactions has been described. The method is applicable to a broad array of electron-rich and neutral aryl fluorides ArF and Ar1F, which are inert under classical SnAr conditions. Although the mechanism of SNAr reactions involving metal arene complexes is hypothesized to involve a stepwise pathway (addition followed by elimination), exptl. data that support this hypothesis is still under exploration. Mechanistic studies and DFT calculations suggest either a stepwise or stepwise-like energy profile. Notably, a rhodium η5-cyclohexadienyl complex intermediate with an sp3-hybridized carbon bearing both a nucleophile and a leaving group was isolated.

Wang, Tao published the artcileA Metal-Free Direct Arene C-H Amination, COA of Formula: C8H10O2, the main research area is aryl amine preparation chemoselective; arene hydroxylamine amination.

Here, a metal-free arene e.g., mesitylene C-H amination using hydroxylamine derivatives 4-(CH3)C6H5S(O)2ON(R)R1 (R = H, Me; R1 = Me, Boc, Bn, etc.) under benign conditions was reported. A charge transfer interaction between the aminating reagents and the arene substrates enables the chemoselective amination of the arene, even in the presence of various functional groups. Oxygen was crucial for an effective conversion and its accelerating role for the electron transfer step was proven exptl. In addition, this was rationalized by a theor. study which indicated the involvement of a dioxygen-bridged complex with a “”Sandwich-like”” arrangement of the aromatic starting materials and the aminating agents at the dioxygen mol.

Yamashiro, Toshiki published the artcileCis-3-Azido-2-methoxyindolines as safe and stable precursors to overcome the instability of fleeting 3-azidoindoles, COA of Formula: C8H10O2, the main research area is arylindole preparation; arene azido alkoxyindole indium catalyst nucleophilic substitution; thioaryl indole preparation; thioarene azido alkoxyindole indium catalyst nucleophilic substitution; azido alkoxyindole preparation; bromo alkoxyindole diastereoselective azidation.

A general and concise approach for tackling this problem by using 3-azidoindole surrogated. The surrogated was bench-stable, presumably due to the observed intramol. O-Nβ bonding. The resultant fleeting intermediates underwent capturing in-situ to afford 3-substitued indoles through formal ipso-substitution of the azide group by nucleophiles. In these investigations, the fleeting 3-azidoindoles showed a C3-electrophilic character for the first time.

Go, Su Yong published the artcileA Unified Synthetic Strategy to Introduce Heteroatoms via Electrochemical Functionalization of Alkyl Organoboron Reagents, HPLC of Formula: 151-10-0, the main research area is organotrifluoroborate preparation electrochem oxidation nucleophilic addition alc ester indole; chiral fluorooxoicosahydropicenyl acetate preparation crystal structure; mol structure chiral fluorooxoicosahydropicenyl acetate; ether sterically congested electrochem preparation; ester sterically congested electrochem preparation; indole sterically congested electrochem preparation; kinetics electrochem oxidation organotrifluoroborate nucleophilic addition alc ester.

Based on systematic electrochem. anal., an integrated synthetic platform of C(sp3)-based organoboron compounds was established for the introduction of heteroatoms. The electrochem. mediated bond-forming strategy is highly effective for the functionalization of sp3-hybridized C atoms with significant steric hindrance. Also, virtually all the nonmetallic heteroatoms could be used as reaction partners using one unified protocol. The observed reactivity stems from the two consecutive single-electron oxidations of the substrate, which eventually generates an extremely reactive carbocation as the key intermediate. The detailed reaction profile could be elucidated through multifaceted electrochem. studies. Ultimately, a new dimension in the activation strategies for organoboron compounds was accomplished through the electrochem. driven reaction development.

Korvinson, Kirill A. published the artcileCatalytic Reductions Without External Hydrogen Gas: Broad Scope Hydrogenations with Tetrahydroxydiboron and a Tertiary Amine, Synthetic Route of 151-10-0, the main research area is arene arylamine benzylic alc chemoselective preparation; palladium catalyst reduction haloarene aryl triflate without hydrogen; hydroxydiboron methylmorpholine chemoselective reductant; chemoselective deuteration haloarene palladium catalyst deuterated hydroxyboron DMAP; deuteriation; diboron; hydrogenation; reduction; tetrahydroxydiboron.

Aryl bromides, iodides, chlorides, and triflates, benzylic halides and ethers, benzyl carbamates, alkenes, alkynes, azides, and aldehydes underwent reductive cleavage, hydrogenation, and reduction reactions using B2(OH)4 as reductant in the presence of Pd/C and 4-methylmorpholine. Aryl dihalides containing two different halogen atoms underwent selective reduction, with reduction of I favored over reduction of Br and Cl, and Br reduction favored over the reduction of Cl. Cyano groups were unaffected, but nitro group and ketones underwent reduction to a low extent. B2(OD)4 and N,N-bis(methyl-d3)pyridin-4-amine (DMAP-d6) were used as reagents for the reductive deuteration of aryl halides. Hydrogen gas has been observed to form with this reagent combination.
