Sen, Abhijit;Dhital, Raghu N.;Sato, Takuma;Ohno, Aya;Yamada, Yoichi M. A. research published 《 Switching from Biaryl Formation to Amidation with Convoluted Polymeric Nickel Catalysis》, the research content is summarized as follows. A stable, reusable, and insoluble poly(4-vinylpyridine) nickel catalyst (P4VP-NiCl2) was prepared through the mol. convolution of poly(4-vinylpyridine) (P4VP) and nickel chloride. The authors proposed a coordination structure of the Ni center in the precatalyst based on elemental anal. and Ni K-edge XANES, and they confirmed that it is consistent with Ni K-edge EXAFS. The Suzuki-Miyaura-type coupling of aryl halides and arylboronic esters proceeded using P4VP-NiCl2 (0.1 mol % Ni) to give the corresponding biaryl compounds in up to 94% yield. Surprisingly, when the same reaction of aryl halides and arylboronic acid/ester was carried out in the presence of amides, the amidation proceeded predominantly to give the corresponding arylamides in up to 99% yield. In contrast, the reaction of aryl halides and amides in the absence of arylboronic acid/ester did not proceed. P4VP-NiCl2 successfully catalyzed the lactamization for preparing phenanthridinone. P4VP-NiCl2 was reused five times without significant loss of catalytic activity. Pharmaceuticals, natural products, and biol. active compounds were synthesized efficiently using P4VP-NiCl2 catalysis. Nickel contamination in the prepared pharmaceutical compounds was not detected by ICP-MS anal. The reaction was scaled to multigrams without any loss of chem. yield. Mechanistic studies for both the Suzuki-Miyaura and amidation reactions were performed.
1120-90-7, 3-Iodopyridine is a heteroaryl halide. It undergoes microwave-assisted coupling with heterocyclic compounds (pyrazole, imidazole, pyrrole and indole) to afford the corresponding N-3-pyridinyl-substituted heterocyclic compounds.
3-Iodopyridine is a useful research chemical used as a reactant in the copper-catalyzed coupling of alkylamines and aryl iodides.
3-Iodopyridine is an isomeric compound that can be synthesized by cross-coupling reactions. This compound has been shown to have nicotinic acetylcholine receptor binding properties and may be useful in the treatment of Alzheimer’s disease. 3-Iodopyridine is a primary amino acid that can be used for the synthesis of amines, which are nitrogen nucleophiles. It has been crystallized with halides and its x-ray structures have been determined. The nmr spectra of 3-iodopyridine show that it contains phosphorus and nitrogen atoms. 3-Iodopyridine is also able to take up nitrate ions from solution, which may be due to its uptake properties., Category: iodides-buliding-blocks
