Reference of 1,2-DiiodoethaneIn 2018 ,《Radical Anions from Urea-type Carbonyls: Radical Cyclizations and Cyclization Cascades》 appeared in Angewandte Chemie, International Edition. The author of the article were Huang, Huan-Ming; McDouall, Joseph J. W.; Procter, David J.. The article conveys some information:
Radical anions generated from urea carbonyls by reductive electron transfer are exploited in carbon-carbon bond formation. New radical cyclizations of urea radical anions deliver complex nitrogen heterocycles and, depending upon the proton source used in the reactions, a chemoselective switch between reaction pathways can deliver two heterobicyclic scaffolds. A computational study has been used to investigate the selectivity of the urea radical processes. Furthermore, radical cyclization cascades involving urea radical anions deliver unusual spirocyclic aminal architectures. After reading the article, we found that the author used 1,2-Diiodoethane(cas: 624-73-7Reference of 1,2-Diiodoethane)
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.Reference of 1,2-Diiodoethane
