Action of bromine in concentrated nitric acid allows carrying out mono- and polybromination of moderately deactivated aromatic compounds 4-Chloronitrobenzene and isophthalic acid turnes into 3-bromo-4-chloronitrobenzene and 5-bromoisophthalic acid at reaction with bromine in concentrated nitric acid at 20°C whereas in absence of bromine in the same conditions 4-chloro-1,3-dinitrobenzene and 5-nitroisophthalic acid are formed accordingly. Presence of bromine in concentrated nitric acid changes nitrating capacity to brominating one. Terephthalic acid and phthalic anhydride at heating with bromine in concentrated nitric acid can be transformed to appropriating tetrabromo substituted compounds

Single-electron transmetalation is recognized as an enabling technol. for the mild transfer of alkyl groups to transition metal catalysts in cross-coupling reactions. Hypercoordinate silicates represent a new and improved class of radical precursors because of their low oxidation potentials and the innocuous byproducts generated upon oxidation Herein, authors report the cross-coupling of secondary and primary ammonium alkylsilicates with (hetero)aryl bromides in good to excellent yields. The base-free conditions have exceptional protic group tolerance on both partners, permitting the cross-coupling of unprotected primary and secondary amines.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-Bromo-4-chloronitrobenzene( cas:16588-26-4 ) is researched.SDS of cas: 16588-26-4.Jorgensen, William L.; Bollini, Mariela; Thakur, Vinay V.; Domaoal, Robert A.; Spasov, Krasimir A.; Anderson, Karen S. published the article 《Efficient Discovery of Potent Anti-HIV Agents Targeting the Tyr181Cys Variant of HIV Reverse Transcriptase》 about this compound( cas:16588-26-4 ) in Journal of the American Chemical Society. Keywords: HIV Reverse Transcriptase inhibitor antiaids pyrimidinyl benzonitrile analog preparation. Let’s learn more about this compound (cas:16588-26-4).

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) that interfere with the replication of human immunodeficiency virus (HIV) are being pursued with guidance from mol. modeling including free-energy perturbation (FEP) calculations for protein-inhibitor binding affinities. The previously reported pyrimidinylphenylamine 1 (I) and its chloro analog 2 are potent anti-HIV agents; they inhibit replication of wild-type HIV-1 in infected human T-cells with EC50 values of 2 and 10 nM, resp. However, they show no activity against viral strains containing the Tyr181Cys (Y181C) mutation in HIV-RT. Modeling indicates that the problem is likely associated with extensive interaction between the dimethylallyloxy substituent and Tyr181. As an alternative, a phenoxy group is computed to be oriented in a manner diminishing the contact with Tyr181. However, this replacement leads to a roughly 1000-fold loss of activity for 3 (2.5 μM). The present report details the efficient, computationally driven evolution of 3 to novel NNRTIs with sub-10 nM potency toward both wild-type HIV-1 and Y181C-containing variants. The critical contributors were FEP substituent scans for the phenoxy and pyrimidine rings and recognition of potential benefits of addition of a cyanovinyl group to the phenoxy ring.

Hypervalent alkylsilicates represent new and readily accessible precursors for the generation of alkyl radicals under photoredox conditions. Alkyl radicals generated from such silicates serve as effective hydrogen atom abstractors from thiols, furnishing thiyl radicals. The reactive sulfur species generated in this manner can be funneled into a nickel-mediated cross-coupling cycle employing aromatic bromides to furnish thioethers. The serendipitous discovery of this reaction and its utilization for the thioetherification of various aryl and heteroaryl bromides with a diverse array of thiols are described. The S-H selective H atom abstraction event enables a wide range of functional groups, including those bearing protic moieties, to be tolerated.

Author is Lim, Taeho; Ryoo, Jeong Yup; Jang, Mingyeong; Han, Min Su.

In this study, a highly efficient Suzuki-Miyaura (SM) cross-coupling was developed using metal oxide catalysts: 0.02 mol% Pd, aqueous solvent, no ligand, and room temperature Metal oxides containing low Pd content (ppm scale) were prepared by a simple co-precipitation method and used as a catalyst for the SM reaction. A fluorescence-based high-throughput screening (HTS) method was developed for the rapid evaluation of catalytic activity and reaction conditions. Among the various metal oxides, Pd/Fe2O3 showed the highest activity for the SM reaction. After further optimization by HTS, various biaryl compounds RR1 (R = 2-formylphenyl, 4-fluorophenyl, 2-chloro-5-nitrophenyl, etc.; R1 = Ph, 6-methoxynaphthalen-2-yl, pyren-1-yl, 4-fluoro-2-methylphenyl) were obtained under optimal conditions: Pd/Fe2O3 (0.02 mol% Pd) in aqueous ethanol at mild temperature without any ligands.

Author is Everly, Charles R.; Traynham, James G..

Photoinitiated chlorination of p-ClC6H4NO2 (I) in CCl4 at room temperature produces mainly p-Cl2C6H4 (II) and some Cl3C6H3 (III). Reaction of p-BrC6H4NO2 (IV) under the same conditions also produces II and III plus a small amount of 2,4-Br(O2N)C6H3Cl (V). The presence of rearrangement product V and the greater III/II ratio from IV than from I are strong evidence for the formation and rearrangement of an ipso intermediate in these aromatic free-radical chlorinations.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Highly Active and Chemoselective Reduction of Halogenated Nitroarenes Catalyzed by Ordered Mesoporous Carbon Supported Platinum Nanoparticles, published in 2019-05-06, which mentions a compound: 16588-26-4, mainly applied to reduction halogenated nitroarene catalyzed carbon platinum nanoparticle, Application In Synthesis of 3-Bromo-4-chloronitrobenzene.

Highly dispersed Pt nanoparticles (∼2.2 nm) on ordered mesoporous carbon (Pt/CMK-3-HQ) were first prepared through a two-step impregnation route with aqueous solutions of 8-hydroxyquinoline (8-HQ) and H2PtCl6, resp. The Pt/CMK-3-HQ quant. converted various halogenated nitroarenes to the corresponding haloanilines using hydrazine hydrate with unprecedented activities (e.g., turnover frequency for o-chloronitrobenzene was 30.2 s-1) and exhibited high stability with 20 cycles without decrease in catalytic efficiency. The high activity and chemoselectivity of Pt/CMK-3-HQ were attributed to the cooperation effect between Pt and N species, promoting cleavage of hydrazine to generate more Pt-H- and N-H+ species for reduction of nitro groups and weakening the interaction between halogen groups and Pt atoms for activation of C-halogen bonds.
