The synthesis of diarylsulfones with simple arenes and K_2S_2O_8 through double C-S bond formation

摘要

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 K_2S_2O_8 can be employed as a highly effective sulfonating agent to synthesize diarylsulfones. The reaction demonstrates excellent reactivity, good functional group tolerance and high yields.
