In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Efficient ligand-free copper-catalyzed N-arylation of amides with aryl halides in water, published in 2011-03-16, which mentions a compound: 7661-33-8, mainly applied to copper catalyzed arylation cross coupling amide aryl iodide, Recommanded Product: 1-(4-Chlorophenyl)pyrrolidin-2-one.
A convenient and efficient protocol has been developed for the cross-coupling of amides and aryl iodides using a ligand-free copper(I) oxide catalyst in water. A variety of amide derivatives afforded the corresponding N-arylated products in moderate to good yields (up to 88%).
In addition to the literature in the link below, there is a lot of literature about this compound(1-(4-Chlorophenyl)pyrrolidin-2-one)Recommanded Product: 1-(4-Chlorophenyl)pyrrolidin-2-one, illustrating the importance and wide applicability of this compound(7661-33-8).
