Introducing a new discovery about 4923-87-9, Name is 5-Bromobenzothiophene
Diaryl formation is achieved by coupling phenols and (hetero)aryl halides under the catalysis of CuI/N,N?-bis(2-phenylphenyl) oxalamide (BPPO) or CuI/N-(2-phenylphenyl)-N?-benzyl oxalamide (PPBO) at 90 C using DMF or MeCN as the solvent. Only 0.2-2 mol % CuI and ligand are required for complete conversion, which represents the lowest catalytic loadings for a general Cu/ligand-catalyzed diaryl ether formation.
