Kim, Mingi; Ryu, Chan Hee; You, Dong Kyun; Hong, Ju Hyun; Lee, Kang Mun published an article in 2022. The article was titled 《Crucial Factors Regulating Intramolecular Charge-Transfer-Based Radiative Efficiency in ortho-Carboranyl Luminophores: Planarity between Substituted Biphenyl Rings》, and you may find the article in ACS Omega.Name: 1-Bromo-2-isopropylbenzene The information in the text is summarized as follows:

O-Carboranyl compounds contain specific geometries, ranging from planar to orthogonally distorted biphenyl rings. Herein, 13 o-carboranyl compounds, 1HF-13PP, were synthesized and fully characterized to determine the impact of structural formation of the aromatic group appended with the o-carborane to estimate the efficiency of their radiative decay process. All the compounds exhibited significant intramol. charge transfer (ICT)-based emission in the crystalline state at 298 K. Remarkably, increasing the distorted dihedral angles between biphenyl rings gradually decreased the emission efficiencies. Also, their radiative decay constants decreased linearly with increasing dihedral angles, which demonstrated the inversely proportional relation between these two factors. These findings distinctly suggest that the planar or distorted geometry of substituted aryl groups can strongly affect the efficiency of the ICT-based radiative process in o-carboranyl luminophores.1-Bromo-2-isopropylbenzene(cas: 7073-94-1Name: 1-Bromo-2-isopropylbenzene) was used in this study.

A series of P-chirogenic Xantphos ligands and related diaryl ether diphosphines have been synthesized by a modification of the well-established Jugé method. The approach consists of the in situ deboranation of the chiral ephedrine-based phosphinite before the P-C coupling takes place. The stereochem. integrity of the stereocenters of the diphosphines during synthesis, long-time storage, and catalytic application was evaluated. In the rhodium-catalyzed asym. hydrogenation of isophorone as a model substrate for industrially relevant pro-stereogenic enones with some of the diphosphines, almost complete conversion, high chemoselectivity, and 96% ee were achieved.

A palladium/DPEphos-catalyzed intermol. trans-selective carbofunctionalization of internal alkynes was established herein. This method proceeds through a formal anti-carbopalladation, forming trans-alkenyl palladium species, which was trapped by aryl boronic acids to provide all-carbon tetrasubstituted alkenes in 32-92% yields. The trans-selective arylsilylation/remote C-H silylation and hydroarylation/remote C-H borylation of internal alkynes were also achieved by using hexamethyldisilane and bis(pinacolato)diboron as trapping reagents, resp. The reaction features good regio- and stereoselectivity and high functional group tolerance. A preliminary mechanistic study and DFT calculations show that a cis to trans isomerization of cis-alkenyl palladium species was involved in this transformation.

A palladium NNC-pincer complex efficiently catalyzed the direct arylation of thiophene derivatives with extremely low palladium loadings of the order of ppm. Thus, the reaction of various thiophenes with aryl bromides in the presence of 25-100 mol ppm of chlorido[(2-phenyl-κ- C2)-9-phenyl-1,10-phenanthroline-κ2-N,N’]palladium(II) NNC-pincer complex, K 2CO3 and pivalic acid in N,N-dimethylacetamide afforded the corresponding 2- or 5-arylated thiophenes I [R1 = H, 5-Cl, 5-Me; Ar = Ph, 4-MeC6H4, 1-naphthyl, etc.] and II [R = 2-Cl, 2-Me, 2-Ph-3-Me, etc.; Ar = 4-MeC6H4] in good to excellent yields. A combination of the present C-H arylation and Hiyama coupling with the same NNC-pincer complex provided an efficient synthesis of unsym. 2,5-thiophenes II [R = 2-(4-MeOC6H4), 2-(4-F3CC6H4); Ar = 4-MeC6H4] with catalyst loadings at mol ppm levels.

In 2018,Vile, Gianvito; Richard-Bildstein, Sylvia; Lhuillery, Arnaud; Rueedi, Georg published 《Electrophile, Substrate Functionality, and Catalyst Effects in the Synthesis of α-Mono and Di-Substituted Benzylamines via Visible-Light Photoredox Catalysis in Flow》.ChemCatChem published the findings.COA of Formula: C9H11Br The information in the text is summarized as follows:

Herein, facile and one-pot synthesis of α-mono- and di-substituted benzylamines from cheap and readily available α-amino acids, via photocatalytic decarboxylative arylation in flow is reported. This enables to access intermediates and building blocks that are difficult to obtain via other synthetic routes, but are key for the manufacture of pharmaceuticals, agrochems., and fine chems. The optimal decarboxylative conditions were identified through a high-throughput evaluation of catalysts, organic or inorganic bases, ligands, and reaction parameters (i.e., contact time, temperatures, and photoelectron power). The reaction turned out to be electronically controlled as the yields increased with increasing electron-d. on the aryl moiety. The results were correlated with the redox properties of the photocatalysts, deriving catalyst structure-performance relationships which can facilitate the future identification of even better materials. In addition, compared to traditional batch chem., the use of a flow protocol led to quicker reactions (30 min instead of 12-72 h) and ensured more predictable reaction scale-ups. In the experiment, the researchers used many compounds, for example, 1-Bromo-2-isopropylbenzene(cas: 7073-94-1COA of Formula: C9H11Br)

A central-to-axial chirality conversion strategy is used for the construction of C-N axially chiral N-arylpyrroles I (R = H, 4-Me, naphthalen-1-yl, thiophen-2-yl, etc.; R1 = Br, I, Me, etc.; R2 = H, Me; R2R3 = phenyl) via a gold(I)-catalyzed 5-endo-dig cyclization/dehydration cascade from amino acid derivatives RCH(NH2)C(O)OH. The reaction exhibits high efficiency on the central-to-axial chirality conversion. D. functional theory calculations suggest that the stereospecificity during the central-to-axial chirality conversion lies in the stability of the conformations of the amino alc. and the corresponding low barrier transition state.

Computed Properties of C9H11BrIn 2020 ,《Fine Tuning of Chiral Bis(N-heterocyclic carbene) Palladium Catalysts for Asymmetric Suzuki-Miyaura Cross-Coupling Reactions: Exploring the Ligand Modification》 was published in Organometallics. The article was written by Zhang, Dao; Yu, Jueqin. The article contains the following contents:

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.
