A mild and efficient synthesis of diaryl sulfones from arylboronic acids and arylsulfonyl hydrazides is described. Promoted by cupric acetate and in the absence of additional ligand and base, the cross-coupling reaction could afford a series of unsymmetrical diaryl sulfones in moderate to good yields at room temperature under neutral and ambient conditions.
