  A variety of substituted diarylsulfones could be synthesized by simple arenes and 3CdSO(4)center dot xH(2)O in the presence of P2O5 under high-speed ball milling. It was suggest the aromatic sulfonation was performed by arene and in situ generated H2SO4, following-up by electrophilic substitution with another arene to give diarylsulfone. (C) 2019 Elsevier Ltd.

  To provide a solid polymer electrolyte composition that can improve oxidation resistance without causing decrease in proton conductivity, elution of added components and the like, and an ion-exchange membrane, a membrane electrode assembly and a fuel cell, each using the composition. It is possible to obtain a solid polymer electrolyte composition having excellent oxidation resistance without causing decrease in proton conductivity, elution of added components and the like, by mixing an aromatic hydrocarbon-based polymer electrolyte, a phosphorus-containing polymer compound and a metallic element.

• The synthesis of diarylsulfones with simple arenes and K₂S₂O₈through double C–S bond formation
  作者：Yiqing Yang、Zhang Chen、Yu Rao

  DOI：10.1039/c4cc05964f

  日期：——

  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.
