An unprecedented ligand-free copper-catalyzed O-arylation of arenesulfonamides with phenols has been developed. Thus, a range of unsysmmetric biaryl ethers were synthesized in excellent yields. The reaction occurs efficiently with excellent regioselectivity through the cleavage of Cary–S bond and with a good tolerance of functional groups on the phenyl ring of phenols. The reaction is appreciated for its readily accessible substrates, mild conditions, and simple operation under air.
Arylmethanesulfonates are convenient latent phenols in the nucleophilic aromatic substitution reaction

The methanesulfonyl protecting group for a phenol is conveniently unmasked under the conditions of the S(N)Ar reaction with an activated aryl halide, producing diarylether products directly. The method is advantageous when the preparation of a phenol substrate requires O-protection, since the selection of the robust methanesulfonate as a latent phenol obviates a deprotection step prior to the S(N)Ar reaction.
