Recommanded Product: 7661-33-8. 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-(4-Chlorophenyl)pyrrolidin-2-one, is researched, Molecular C10H10ClNO, CAS is 7661-33-8, about Facile CuI-catalyzed arylation of azoles and amides using simple enaminones as efficient ligands. Author is Cheng, Cungui; Sun, Gonglei; Wan, Jieping; Sun, Cuirong.
(E)-3-(Dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one was found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 °C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.
