DOI: 10.1039/d0qo01238f
Abstract: An efficient silver-catalyzed δ-regioselective C(sp3)–H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp2)–H alkylation products in 31–89%… read more here.
