In 2015,Vitaku, Edon; Njardarson, Jon T. published 《Formation of fused aromatic architectures via an oxidative dearomatization-radical cyclization rearomatization approach》.Tetrahedron Letters published the findings.Recommanded Product: 624-73-7 The information in the text is summarized as follows:
A new mild C-C bond forming cyclization approach of catechol derivatives is reported. This approach relies on an initial dearomatization step using lead(IV) acetate followed by a carefully controlled radical cyclization step, which under the reaction conditions also facilitates rearomatization. Triethylborane is key to the success of this reaction as it enables the reaction to proceed at low temperatures and is also believed to aid rearomatization. The amount and ratio of triethylborane and reducing agent (tributyltinhydride) that is employed as well as the concentration the reaction is run at are all essential to the success of this new approach.1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 624-73-7) was used in this study.
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Recommanded Product: 624-73-7
