Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons-Smith reaction (cyclopropanation using iodomethane), 5029-67-4, formula is C5H4IN, Name is 2-Iodopyridine. Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction. Formula: C5H4IN.
Shiels, Oisin J.;Kelly, P. D.;Bright, Cameron C.;Poad, Berwyck L. J.;Blanksby, Stephen J.;da Silva, Gabriel;Trevitt, Adam J. research published 《 Reactivity Trends in the Gas-Phase Addition of Acetylene to the N-Protonated Aryl Radical Cations of Pyridine, Aniline, and Benzonitrile》, the research content is summarized as follows. A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N-containing aromatics In cold diffuse environments, such as the interstellar medium, rates of radical addition may be enhanced when the σ-type radical is charged. This paper investigates the gas-phase ion-mol. reactions of acetylene with nine aromatic distonic σ-type radical cations derived from pyridinium (Pyr), anilinium (Anl), and benzonitrilium (Bzn) ions. Three isomers are studied in each case (radical sites at the ortho, meta, and para positions). Using a room temperature ion trap, second-order rate coefficients, product branching ratios, and reaction efficiencies are measured. The rate coefficients increase from para to ortho positions. The second-order rate coefficients can be sorted into three groups: low, between 1 and 3 x 10-12 cm3 mol.-1 s-1 (3Anl and 4Anl); intermediate, between 5 and 15 x 10-12 cm3 mol.-1 s-1 (2Bzn, 3Bzn, and 4Bzn); and high, between 8 and 31 x 10-11 cm3 mol.-1 s-1 (2Anl, 2Pyr, 3Pyr, and 4Pyr); and 2Anl is the only radical cation with a rate coefficient distinctly different from its isomers. Quantum chem. calculations, using M06-2X-D3(0)/6-31++G(2df,p) geometries and DSD-PBEP86-NL/aug-cc-pVQZ energies, are deployed to rationalize reactivity trends based on the stability of prereactive complexes. The G3X-K method guides the assignment of product ions following adduct formation. The rate coefficient trend can be rationalized by a simple model based on the prereactive complex forward barrier height.

2-Iodopyridine is a halogenated building block. It is a reagent used in the preparation of human NAD+-dependent 15-hydroxyprostaglandin dehydrogenase inhibitors
2-Iodopyridine is a white crystalline solid that is soluble in water, alcohol, and ether. The molecule contains a methyl group and two iodine atoms. 2-Iodopyridine has several industrial uses. It acts as a precursor to various pharmaceuticals and agrochemicals. The compound also exhibits insulin resistance properties, which may be related to its ability to bind to the insulin receptor and inhibit insulin signaling. 2-Iodopyridine can also be used for treating cancer because it binds to the DNA of cancer cells, preventing replication and leading to cell death.
