In 2015,Gonzalez-de-Castro, Angela; Xiao, Jianliang published 《Green and Efficient: Iron-Catalyzed Selective Oxidation of Olefins to Carbonyls with O2》.Journal of the American Chemical Society published the findings.Related Products of 624-73-7 The information in the text is summarized as follows:
A mild and operationally simple iron-catalyzed protocol for the selective aerobic oxidation of aromatic olefins to carbonyl compounds is described. Catalyzed by a Fe(III) species bearing a pyridine bisimidazoline ligand at 1 atm of O2, α- and β-substituted styrenes were cleaved to afford benzaldehydes and aromatic ketones generally in high yields with excellent chemoselectivity and very good functional group tolerance, including those containing radical-sensitive groups. With α-halo-substituted styrenes, the oxidation took place with concomitant halide migration to afford α-halo acetophenones. Various observations have been made, pointing to a mechanism in which both mol. oxygen and the olefinic substrate coordinate to the iron center, leading to the formation of a dioxetane intermediate, which collapses to give the carbonyl product. Safety: all oxidation reactions should be carried out with caution due to potential fire and explosion hazards. The experimental process involved the reaction of 1,2-Diiodoethane(cas: 624-73-7Related Products of 624-73-7)
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Related Products of 624-73-7
