In 2022,Hosseinzadeh, Rahman; Aghili, Nora; Mavvaji, Mohammad published an article in Polyhedron. The title of the article was 《Synthesis and characterization of nano-cellulose immobilized phenanthroline-copper (I) complex as a recyclable and efficient catalyst for preparation of diaryl ethers, N-aryl amides and N-aryl heterocycles》.HPLC of Formula: 589-87-7 The author mentioned the following in the article:
Functionalized nanocellulose was prepared and employed for immobilization of phenanthroline-copper(I) complex to afford cellulose nanofibril grafted heterogeneous copper catalyst [CNF-phen-Cu(I)]. The activities of the synthesized catalyst were examined in the synthesis of diaryl ethers RC6H4OR1 (R = H, 4-Me, 4-Br, 4-NO2, etc.; R1 = Ph, 4-methylphenyl, 2-naphthyl, etc.) via C-O cross-coupling of phenols R1OH and aryl iodides RC6H4X (X = I, Br), as well as, the preparation of N-aryl amides/N-aryl heterocycles R2C6H4R3 (R2 = Ph, 1-naphthyl, 4-bromophenyl, etc.; R3 = benzoylamino, acetylamino, 1H-indol-1-yl, etc.) through C-N cross-coupling of amides/N-H heterocyclic compounds R3H with aryl halides R2C6H4X (X = I, Br). In this trend, various substrates containing electron-donating and electron-withdrawing groups were exploited to evaluate the generality of this catalytic protocol. Accordingly, the catalyst demonstrated remarkable catalytic efficiency for both C-N and C-O cross-coupling reactions, thereby resulting in good to excellent yields of the desired products. Furthermore, the recoverability experiments of the catalyst showed that it can be readily retrieved by simple filtration and successfully reused several times with negligible loss of its catalytic activity. In the experiment, the researchers used 1-Bromo-4-iodobenzene(cas: 589-87-7HPLC of Formula: 589-87-7)
1-Bromo-4-iodobenzene(cas: 589-87-7) has been employed as reagent for in situ desilylation and coupling of silylated alkynes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids), as substrate in copper-free Sonogashira coupling in aqueous acetone in synthesis of β,β,dibromostyrenesHPLC of Formula: 589-87-7
