In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Selective Copper-Catalyzed N-Arylation of Lactams with Arylboronic Acids under Base- and Ligand-Free Conditions, published in 2015-06-30, which mentions a compound: 7661-33-8, Name is 1-(4-Chlorophenyl)pyrrolidin-2-one, Molecular C10H10ClNO, Product Details of 7661-33-8.
An oxidative copper-catalyzed cross-coupling of arylboronic acids with various ring-size lactams has been developed. The N-arylated lactams were obtained in moderate to excellent yields without any addnl. bases, ligands, or additives. This reaction shows complete selectivity for N-arylation of lactams in the presence of a hydroxyl group.
