Couplings between (hetero)arylchlorides and phenols can be effectively promoted by CuI in combination with an N‐aryl‐N′‐alkyl‐substituted oxalamide ligand to proceed smoothly at 120 °C. For this process, N‐aryl‐N′‐alkyl‐substituted oxalamides are more effective ligands than bis(N‐aryl)‐substituted oxalamides. A wide range of electron‐rich and electron‐poor aryl and heteroaryl chlorides gave the corresponding

the substituents on the phenol on the regiochemtstry of the arylation reactions with Ph3BiCl2 and other bismuth reagents has been studied. -Phenylation occurs with phenols substituted with electron-withdrawing groups. Electron-donating substituted phenols undergo -phenylation. Oxidative dimerisation has been observed with 2,6-dialkyl phenols.
