In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. 1120-90-7, formula is C5H4IN, Name is 3-Iodopyridine.Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Electric Literature of 1120-90-7.
Wang, Xiaoshuang;Sun, Lei;Wang, Miaomiao;Maestri, Giovanni;Malacria, Max;Liu, Xiang;Wang, Yanlan;Wu, Lingang research published 《 C-I Selective Sonogashira and Heck Coupling Reactions Catalyzed by Aromatic Triangular Tri-palladium》, the research content is summarized as follows. Aromatic triangular tri-palladium cations, abbreviated as [Pd3]+, have shown interesting photoelec. properties, Lewis basic character, and excellent activities in catalytic hydrogenation. Herein, authors report the highly efficient and C-I selective Sonogashira and Heck coupling reactions catalyzed by these tri-palladium complexes. Benefiting from the moderate C-I bond association energy, these tri-palladiums presented exclusive reactivities to aryl iodides over the brominated aromatics in coupling reactions. In the Sonogashira pathway, good to excellent isolated yields (71-95%) were achieved. Gram-scale reaction reached 93% of yield with palladium loading as few as 0.06 mol %. Authors also explored the electronic and steric effects for Ph alkynes and aryl iodides including heteroaromatics like thiophene, pyridine, pyrazole, and pyrazine. Similarly, yields of 71-96% were obtained for palladium loading of 1.5 mol% through catalyzed Heck coupling of aryl iodides and alkenes. The HRMS monitoring revealed that [Pd3]+ maintained as whole entity during the catalytic process due to its robusness.
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., Electric Literature of 1120-90-7
