And the article was included in Journal of Medicinal Chemistry in 2022.Recommanded Product: 1-Bromopyrrolidine-2,5-dione This article mentions the following:

The recent crystallization of the neuropeptide Y Y₁ receptor (Y₁R) in complex with the argininamide-type Y₁R selective antagonist UR-MK299 (2) opened up a new approach toward structure-based design of nonpeptidic Y₁R ligands. We designed novel fluorescent probes showing excellent Y₁R selectivity and, in contrast to previously described fluorescent Y₁R ligands, considerably higher (~100-fold) binding affinity. This was achieved through the attachment of different fluorescent dyes to the diphenylacetyl moiety in 2 via an amine-functionalized linker. The fluorescent ligands exhibited picomolar Y₁R binding affinities (pK_i values of 9.36-9.95) and proved to be Y₁R antagonists, as validated in a Fura-2 calcium assay. The versatile applicability of the probes as tool compounds was demonstrated by flow cytometry- and fluorescence anisotropy-based Y₁R binding studies (saturation and competition binding and association and dissociation kinetics) as well as by widefield and total internal reflection fluorescence (TIRF) microscopy of live tumor cells, revealing that fluorescence was mainly localized at the plasma membrane. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Recommanded Product: 1-Bromopyrrolidine-2,5-dione).

1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon闁艰京鐗梤omine bond is electrophilic in nature. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Recommanded Product: 1-Bromopyrrolidine-2,5-dione

In this protocol Ni-catalyzed reductive arylalkylation of unactivated alkenes tethered to aryl bromides with primary alkyl bromides was accomplished, which provided a new path to construct diverse benzene-fused carbo- and heterocyclic cores including indanes, tetrahydroisoquinolines, indolines and isochromanes I [R¹ = Me, Et, i-Pr, cyclohexyl; R² = H, Me, Et; R³ = 5-OMe, 5-F, 4-Cl, etc.; R⁴ = CN, OAc, F, etc.; X = CH₂, NH, NMe, O; m = 0,3,4,5,6; n = 0,1].

Nickel-Catalyzed Cross-Electrophile C(sp³)-Si Coupling of Unactivated Alkyl Bromides with Vinyl Chlorosilanes was written by Duan, Jicheng;Wang, Yuquan;Qi, Liangliang;Guo, Peng;Pang, Xiaobo;Shu, Xing-Zhong. And the article was included in Organic Letters in 2021.Recommanded Product: 1-Bromo-4-methoxybutane This article mentions the following:

Cross-electrophile C-Si coupling has emerged as a promising tool for the construction of organosilanes, but the potential of this method remains largely unexplored. Herein, we report a C(sp³)-Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alc., ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl fluoride and chloride, aryl bromide, alkyl tosylate and mesylate, silyl ether, and amine were tolerated. Incorporation of the -Si(vinyl)R₂ moiety into complex mols. and the immobilization of a glass surface by formed organosilanes were demonstrated. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Recommanded Product: 1-Bromo-4-methoxybutane).

1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Recommanded Product: 1-Bromo-4-methoxybutane

On the Scope of Trimethylaluminum-Promoted 1,2-Additions of ArZnX Reagents to Aldehydes was written by Glynn, Daniel;Shannon, Jonathan;Woodward, Simon. And the article was included in Chemistry – A European Journal in 2010.Recommanded Product: 35065-86-2 This article mentions the following:

A practical asym. 1,2-addition of functionalized arylzinc halides to aromatic and aliphatic aldehydes is described by the use of aminoalc. catalysis in the presence of AlMe₃. The process is simple to carry out, uses only com. available reagents/ligands and provides moderate to good (80-96 % ee) enantioselectivities for a wide range of substrates. Either com. ArZnX reagents or those prepared in situ from low cost aryl bromides can be used. In the latter case electrophilic functional groups are tolerated (CO₂Et, CN). The reaction relies on rapid exchange between ArZnX and AlMe₃ to generate mixed organometallic species that lead to the formation of a key intermediate that is distinctly different from the classic “anti” transition states of Noyori. NMR monitoring and related experiments have been used to probe the validity of the proposed selective transition state. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Recommanded Product: 35065-86-2).

Intramolecular Charge-Transfer Interaction in a New Dyad Based on C₆₀ and Bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA) Donor was written by Ohno, Toshinobu;Moriwaki, Kazuyuki;Miyata, Toshiyuki. And the article was included in Journal of Organic Chemistry in 2001.Synthetic Route of C16H17Br This article mentions the following:

A novel methanofullerene dyad based on C₆₀ and bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA) has been prepared and characterized. Cyclic voltammetry (CV) and UV-vis spectra of the C₆₀-BBA methanofullerene dyad, 61-phenyl-1,2-methanofullerene[60], 1,2-methanofullerene[60], and BBA were measured and analyzed. CV measurements showed that a reversible oxidation wave of the C₆₀-BBA methanofullerene dyad was pos. shifted by 40 mV compared to that of BBA. More remarkably, comparing UV-vis spectra of the C₆₀-BBA methanofullerene dyad and 1,2-methanofullerene[60] shows a large increase in intensity for a broad band at 500 nm in the dyad despite the lack of an absorbance at >400 nm for BBA. These results indicate the presence of charge-transfer interactions in the C₆₀-BBA methanofullerene dyad between the fullerene moiety and diarylaniline moieties. In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Synthetic Route of C16H17Br).

4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5).
