On December 31, 2022, Ji, Peng; Davies, Cassondra C.; Gao, Feng; Chen, Jing; Meng, Xiang; Houk, Kendall N.; Chen, Shuming; Wang, Wei published an article.Computed Properties of 93-04-9 The title of the article was Selective skeletal editing of polycyclic arenes using organophotoredox dearomative functionalization. And the article contained the following:

A general organophotoredox approach for the chemo- and regioselective dearomatization of structurally diverse polycyclic aromatics, including quinolines, isoquinolines, quinoxalines, naphthalenes, anthracenes and phenanthrenes was described. The success of the method for chemoselective oxidative rupture of aromatic moieties relies on precise manipulation of the electronic nature of the fused polycyclic arenes. Mechanistic studies show that the addition of a hydrogen atom transfer (HAT) agent helps favor the dearomatization pathway over the more thermodynamically downhill aromatization pathway. This strategy was applied to rapid synthesis of biol. valued targets and late-stage skeletal remodeling en route to complex structures. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Computed Properties of 93-04-9

On April 27, 2020, Zhang, Dao; Yu, Jueqin published an article.Safety of 2-Methoxynaphthalene The title of the article was Fine Tuning of Chiral Bis(N-heterocyclic carbene) Palladium Catalysts for Asymmetric Suzuki-Miyaura Cross-Coupling Reactions: Exploring the Ligand Modification. And the article contained the following:

Novel chiral N,N’-bisaryl bis(NHC) ligand precursors H2[(S)-2]Cl2 on a spiro scaffold and H2[(S)-3b-g]Cl2 with a binaphthyl linkage were rationally designed and their cyclometalated cis-chelated NHC Pd complexes (S)-5, (S)-6, and (S)-7b-g were synthesized and fully characterized. Complexes 6 and 7b were further confirmed by x-ray single-crystal anal. Both complexes adopted a slightly distorted square planar geometry around the Pd(II) center. The structure of 6 consists of a rare dimeric arrangement incorporating two Pd(II) centers bonded through a short metal-metal bond (2.853(2) Å), indicating a PdII-PdII intramol. interaction (<3.00 Å). These N,N'-bisaryl-bis(NHC)-Pd complexes together with N,N'-bisalkyl analogs {[(S)-1a-d]PdX2} (X = I, (S)-4a; X = Br, (S)-4b-d) were used in the asym. aryl-aryl cross-coupling reactions of arylboronic acids and aryl halides. The enantioselectivity of the biaryl products was greatly improved within 24 h (up to 74% ee) when complexes 7a-g were used as catalysts. For these types of bis(NHC) Pd catalysts the structural characters of the chiral scaffolds play a decisive role in the enantioselectivities of cross-coupling reactions. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Safety of 2-Methoxynaphthalene

On March 1, 2022, Dalai, Pallaba Ganjan; Palit, Kuntal; Panda, Niranjan published an article.Synthetic Route of 93-04-9 The title of the article was Generation of Dimethyl Sulfoxide Coordinated Thermally Stable Halogen Cation Pools for C-H Halogenation. And the article contained the following:

A method to generate halogen cation pools from the reaction of 1,2-dihaloethanes (hal=Br, I) and DMSO (DMSO) for C-H halogenation of arenes and heteroarenes was reported. The initial reaction of DMSO and 1,2-dihaloethane generates the sulfur ylide, which undergoes pyrolytic elimination of ethylene by affording halonium ions. These ions were accumulated and stabilized by DMSO through coordination by forming halogen cation pools for the halogenation reaction. This protocol was selective for electrophilic monohalogenation of arenes at room temperature; however, polyhalogenated products were formed by raising the reaction temperature Late-stage halogenation of heteroarenes and some commonly marketed drugs signifies the synthetic utility of this protocol in pharmaceutical chem. Unlike the classical methods, the in-situ generated electrophilic bromonium ion was further exploited for the direct synthesis of α-diketones from the alkenes under base-free conditions. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Synthetic Route of 93-04-9

On March 28, 2022, Zhang, Dao; Yu, Jueqin published an article.Reference of 2-Methoxynaphthalene The title of the article was Effect of the Dihedral Angle of Biaryl-Bridged Bis(N-Heterocylic Carbene) Ligands on Enantioselectivity in Pd-Catalyzed Asymmetric Aryl-Aryl Cross-Coupling. And the article contained the following:

New biaryl-bridged bis(N-heterocylic carbene) Pd complexes were synthesized and applied in asym. Suzuki cross-coupling of aryl halide and aryl boronic acid. X-ray crystallog. studies of square-planar Pd complexes of four of these bis(NHC) ligands revealed that the dihedral angle of the bridging biaryl moiety depends on its identity and lies 79.65-92.69°. A linear correlation between the dihedral angle in these Pd complexes and cross-coupling enantioselectivity is 1st reported. Also, larger Ccarbene-Pd-Ccarbene bite angles lead to increased enantioselectivity in a 1st fast and then slow growing tendency.

N-Methoxy-1-butanesulfonamide was a recyclable catalyst for the activation of N-bromosuccinimide to perform bromocyclization and bromination reactions of unsaturated carboxylic acids, alkenes and indoles with pendant nucleophiles, and arenes in heptane, where adequate suppression of the background reactions was observed, to yield bromolactones, bromomethyl-substituted heterocycles, fused indolines such as pyrroloindolines, and aryl bromides. The key feature of the active site is the alkoxy group attached to the sulfonamide moiety, which facilitates the acceptance as well as the delivery of bromonium species from the bromine source to the substrates.

On October 11, 2020, Poole, Colin F. published an article.Computed Properties of 93-04-9 The title of the article was Selection of calibration compounds for selectivity evaluation of wall-coated, open-tubular columns for gas chromatography by the solvation parameter model. And the article contained the following:

To facilitate faster selectivity evaluation of wall-coated, open-tubular columns using the solvation parameter model a reduced set of calibration compounds is identified and validated for the temperature ranges 60-140°C and 160-260°C. The Kennard-Stone uniform mapping algorithm is used to identify the calibration compounds from a larger database of compounds with known retention properties previously adopted for column selectivity evaluation. Thirty-five compounds for each temperature range are required to minimize the standard deviation of the system constants used for selectivity evaluation and to minimize differences between system constants determined by conventional calibration and the reduced calibration compounds The models for the reduced calibration compounds on ten siloxane-based and poly(ethylene glycol) stationary phases have a coefficient of determination of 0.984 to 0.998 and standard error of the estimate of 0.012 to 0.30. The predictive capability of models is evaluated for the reduced sets of calibration compounds using external test sets with ranking of the calibration models by changes in the average error, average absolute error and root mean square error of prediction for the test sets. For the selected thirty-five reduced calibration compounds the range for the average absolute error was 0.014 to 0.033 and 0.016 to 0.040 for the root mean square error of prediction for the independent test sets. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Computed Properties of 93-04-9
