A copper-mediated cross-coupling reaction between HCFC-123 and phenols or thiophenols has been achieved. It is found that diethyl amine, which serves as both the activator and ligand of copper, plays a key role in this reaction. Two possible radical involved processes are proposed for the reaction mechanism.
