Secondary Products from Intramolecular Cycloadditions of Azidoalkyl Enol Ethers and Azidoalkyl Vinyl Bromides: 1-Azadienes, Their Reactions with Diphenylketene, and Radical Cyclizations To Form Bi- and Tricyclic Lactams was written by Liddon, John T. R.;Lindsay-Scott, Peter J.;Robertson, Jeremy. And the article was included in Journal of Organic Chemistry in 2019.Formula: C4H8ClI This article mentions the following:
Azidoalkyl enol ethers undergo intramol. 1,3-dipolar cycloaddition to generate stable triazolines; in contrast, the cycloadducts formed by heating analogous azidoalkyl vinyl bromides are unstable with respect to elimination of N2 and HBr, affording 1-azadienes (2-alkenyl cyclic imines). These primary products may be isolated or treated directly with diphenylketene to produce bi- and tricyclic 3,4-dihydropyridin-2(1H)-ones; similar ring systems may also be produced from the azadienes by N-acylation and radical cyclization. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Formula: C4H8ClI).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Formula: C4H8ClI
