And the article was included in ACS Medicinal Chemistry Letters in 2020.Quality Control of 4-Iodo-1,2-dimethoxybenzene This article mentions the following:

FK506-binding protein 35, FKBP35, has been implicated as an essential malarial enzyme. Rapamycin and FK506 exhibit antiplasmodium activity in cultured parasites. However, due to the highly conserved nature of the binding pockets of FKBPs and the immunosuppressive properties of these drugs, there is a need for compounds that selectively inhibit FKBP35 and lack the undesired side effects. In contrast to human FKBPs, FKBP35 contains a cysteine, C106, adjacent to the rapamycin binding pocket, providing an opportunity to develop targeted covalent inhibitors of Plasmodium FKBP35. Here, we synthesize inhibitors of FKBP35, show that they directly bind FKBP35 in a model cellular setting, selectively covalently modify C106, and exhibit antiplasmodium activity in blood-stage cultured parasites. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Quality Control of 4-Iodo-1,2-dimethoxybenzene).

4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature.

Disassembling Metal Nanocrystallites into Sub-nanometric Clusters and Low-faceted Nanoparticles for Multisite Catalytic Reactions was written by Oliver-Meseguer, Judit;Dominguez, Irene;Gavara, Rafael;Leyva-Perez, Antonio;Corma, Avelino. And the article was included in ChemCatChem in 2017.Product Details of 5460-32-2 This article mentions the following:

Metal nanocrystallites present saturated atoms, in planes, and unsaturated metal atoms, in corners and vertices, for catalytic applications. However, both sites are spatially complementary and simultaneously excluding for a given particle, thus their number cannot be independently maximized for a catalytic process. Here, it is shown that the independent dosage of Au clusters and metallic Au nanoparticles dramatically improves the catalytic activity of Au for the Sonogashira reaction, enabling the coupling of a wide range of iodo-, bromo-, and activated chloro-derivatives with aromatic and aliphatic alkynes, and outperforming ligand-free Pd and Cu catalysts. Mechanistic studies reveal that the unsaturated atoms of the cluster activate the alkyne and that the saturated atoms of the metallic nanoparticle preferentially activate the halide, to finally perform the coupling. Thus, a precise combination of sub-nanometric metal clusters and metal nanoparticles, together, constitute a new catalytic strategy to substitute metal nanocrystallites in reactions in which both unsaturated and saturated atoms play a key role. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Product Details of 5460-32-2).

4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.Product Details of 5460-32-2

Nickel-catalyzed C-H alkylation of indoles with unactivated alkyl chlorides: evidence of a Ni(I)/Ni(III) pathway was written by Pandey, Dilip K.;Ankade, Shidheshwar B.;Ali, Abad;Vinod, C. P.;Punji, Benudhar. And the article was included in Chemical Science in 2019.HPLC of Formula: 10297-05-9 This article mentions the following:

A mild and efficient nickel-catalyzed method for the coupling of inactivated primary ClCH₂R (R = 1-naphthylmethyl, cyclopentyl, SiMe₃, 2-furanylethyl, etc.) and secondary alkyl chlorides XCHR¹R² (X = Cl, Br; R¹ = Me, Ph; R² = Ph; R¹R² = cyclopropyl, cyclohexyl, cycloheptyl, bicyclo[2.2.1]heptan-2-yl) with the C-H bond of indoles I (R³ = H, Me, OMe, F; R⁴ = pyridin-2-yl, pyrazin-2-yl; R⁵ = H, Me) and N-pyridin-2-ylpyrrole is described to demonstrate a high level of chemo and regioselectivity. The reaction tolerates numerous functionalities, such as halide, alkenyl, alkynyl, ether, thioether, furanyl, pyrrolyl, indolyl and carbazolyl groups including acyclic and cyclic alkyls under the reaction conditions. Mechanistic investigation highlights that the alkylation proceeds through a single-electron transfer (SET) process with Ni(I)-species being the active catalyst. Overall, the alkylation follows a Ni(I)/Ni(III) pathway involving the rate-influencing two-step single-electron oxidative addition of alkyl chlorides. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9HPLC of Formula: 10297-05-9).

1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.HPLC of Formula: 10297-05-9

In this work, we have disclosed the nickel-catalyzed unactivated β-C(sp³)-H bond arylation of aliphatic acid derivatives with aryl iodides/bromides via bidentate chelation-assistance of an 8-aminoquinoline moiety. E.g., in presence of a Ni catalyst, arylation of 8-quinolinyl-substituted amide I with 4-IC₆H₄OMe gave 83% II. The best results were obtained by using Ni(OTf)₂ as the catalyst, PPh₃ as the ligand, Na₂CO₃ as the base, PivOH, and DMSO as the additives in dry 1,4-dioxane at 160 °C. These preliminary results indicate the intrinsic catalytic potential of nickel metal for unactivated C(sp³)-H bond arylation.

And the article was included in Journal of the American Chemical Society in 2020.Related Products of 5460-32-2 This article mentions the following:

A photoassisted Ni-catalyzed reductive cross-coupling between tosyl-protected alkyl aziridines and com. available (hetero)aryl iodides is reported. This mild and modular method proceeds in the absence of stoichiometric heterogeneous reductants and uses an inexpensive organic photocatalyst to access medicinally valuable β-phenethylamine derivatives Unprecedented reactivity was achieved with the activation of cyclic aziridines. Mechanistic studies suggest that the regioselectivity and reactivity observed under these conditions are a result of nucleophilic iodide ring opening of the aziridine to generate an iodoamine as the active electrophile. This strategy also enables cross-coupling with Boc-protected aziridines.
