α,β-Unsaturated oxime pivalates are proposed to undergo reversible C(sp2)-H insertion with cationic Rh(III) complexes to furnish five-membered metallacycles. In the presence of 1,1-disubstituted olefins, these species participate in irreversible migratory insertion to give, after reductive elimination, 2,3-dihydropyridine products in good yields. Catalytic hydrogenation can then be used to convert these mols. into piperidines, which are important structural components of numerous pharmaceuticals. Thus, e.g., heterocyclization of unsaturated oxime pivalate I with alkene II in presence of [Rh(MeCN)3(C5Me4CF3)](SbF6)2 afforded dihydropyridine III (99%). In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Related Products of 10297-05-9).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Related Products of 10297-05-9
