Zirconocene-induced cyclization /Elimination reactions of 2-heterosubstituted 1,6-dienes and 1,6-enynes was written by Owen, David R.;Whitby, Richard J.. And the article was included in Synthesis in 2005.Name: 1-Chloro-4-iodobutane This article mentions the following:
Zirconocene-mediated cyclization of 2-heterosubstituted 1,6-diene derivatives and enyne derivatives gave zirconacycles bearing an endocyclic β-leaving group which eliminated under the reaction conditions to provide exocyclic alkylidene groups. The scope of this cyclization/elimination has been investigated along with further elaboration of the monosubstituted zirconocene intermediates by insertion of alkenyl carbenoids. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Name: 1-Chloro-4-iodobutane).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. 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.Name: 1-Chloro-4-iodobutane
