Iodide is one of the largest monatomic anions. It is assigned a radius of around 206 picometers. 1120-90-7, formula is C5H4IN, Name is 3-Iodopyridine.For comparison, the lighter halides are considerably smaller: bromide (196 pm), chloride (181 pm), and fluoride (133 pm). In part because of its size, iodide forms relatively weak bonds with most elements. Category: iodides-buliding-blocks.
Park, Byoung Yong;Lim, Taeho;Han, Min Su research published 《 A simple and efficient in situ generated copper nanocatalyst for stereoselective semihydrogenation of alkynes》, the research content is summarized as follows. (Z)-selective semihydrogenation of alkynes were achieved using a copper nanocatalyst which was generated in situ by adding ammonia borane to an ethanol solution of copper sulfate. Different types of alkynes including aryl-aryl, aryl-alkyl, and aliphatic alkynes were selectively reduced to (Z)-alkenes affording up to 99% isolated yield. The semihydrogenation of terminal alkynes to alkenes and gram-scale applications were also reported. In addition to eliminating catalyst preparation, the proposed approach were simple and practical and served as a suitable alternative method to the conventional Lindlar catalyst.
Category: iodides-buliding-blocks, 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., 1120-90-7.
