Screening of ligands for the Ullmann synthesis of electron-rich diaryl ethers was written by Otto, Nicola;Opatz, Till. And the article was included in Beilstein Journal of Organic Chemistry in 2012.Application In Synthesis of N1,N2-Dimethoxy-N1,N2-dimethyloxalamide This article mentions the following:
In the search for ligands for the Ullmann diaryl ether synthesis, permitting the coupling of electron-rich aryl bromides at relatively low temperatures, 56 structurally diverse multidentate ligands were screened in a model system that uses copper iodide in acetonitrile with potassium phosphate as the base. The ligands differed largely in their performance, but no privileged structural class could be identified. In the experiment, the researchers used many compounds, for example, N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1Application In Synthesis of N1,N2-Dimethoxy-N1,N2-dimethyloxalamide).
N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Application In Synthesis of N1,N2-Dimethoxy-N1,N2-dimethyloxalamide
