HPLC of Formula: 676448-17-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Boc-4-Bromoindole, is researched, Molecular C13H14BrNO2, CAS is 676448-17-2, about Palladium-Catalyzed Conversion of Aryl and Vinyl Triflates to Bromides and Chlorides. Author is Shen, Xiaoqiang; Hyde, Alan M.; Buchwald, Stephen L..
The palladium-catalyzed conversion of aryl and vinyl triflates to aryl and vinyl halides (bromides and chlorides) has been developed using dialkylbiaryl phosphine ligands. A variety of aryl, heteroaryl, and vinyl halides can be prepared via this method in good to excellent yields. E.g., in presence of Pd2(dba)3, t-BuBrettPhos ligand, KBr, PEG3400, 2-butanone, and (iBu)3Al, 4-BuC6H4OSO2CF3 was converted to 82% 4-BuC6H4Br.
