A novel and green nanomagnetic Zn catalyst were fabricated via the immobilization of Zn (II) complex on the surface of magnetic nanoparticles modified with phenanthroline (MNPs-Phen-Zn(II)). The structure of MNPs-Phen-Zn(II) nanomaterial was characterized by spectroscopic techniques including FTIR spectroscopy, SEM, TEM, EDX, XRD, VSM, and ICP-OES. The resulting Zn nanomagnetic catalyst was shown high catalytic activity for the synthesis of disubstituted alkynes via C(sp2)-C(sp) cross-coupling reactions of alkynes with aryl iodides under eco-friendly conditions. It is the first report on the use of Zn nanomagnetic catalyst for the Sonogashira type cross-coupling reaction of alkynes with aryl iodides in the absence of added Pd and Cu sources. The simple preparation of the catalyst from com. available materials, excellent chemoselectivity, easy separation of products, and straightforward recovery and reusability of the catalyst with unaltered activity make the procedure a green and practical method. The results came from multiple reactions, including the reaction of 4-Iodopyridine(cas: 15854-87-2SDS of cas: 15854-87-2)
4-Iodopyridine(cas: 15854-87-2) is a halogenated heterocycle that is a building block for proteomics research. 4-Iodopyridine is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists.SDS of cas: 15854-87-2
