The synthesis of diarylsulfones with simple arenes and K2S2O8 through double C–S bond formation

Abstract

An unprecedented double C–S bond formation method has been developed to prepare both symmetric and unsymmetric diarylsulfones with simple arenes in a single step. This represents the first example that K₂S₂O₈ can be employed as a highly effective sulfonating agent to synthesize diarylsulfones. The reaction demonstrates excellent reactivity, good functional group tolerance and high yields.
