Oxalamide ligands with additional coordinating groups for Cu-catalyzed arylation of alcohols and phenols.

A novel class of chain-like multidentate oxalamide ligands with additional coordinating groups was developed for the coupling of (hetero)aryl bromides with both alcohols and phenols under mild conditions. Introduction of oxygen atoms in N -alkyl chains is pivotal for the high catalytic efficiency and broad substrate versatility.
