Synthesis of Diaryl Sulfoxides Using Poly(4-vinylpyridine)-Supported Brønsted Ionic Liquid as a Catalyst

Poly(4-vinylpyridine)-supported Brønsted ionic liquid was easily prepared from its starting materials and used as a novel, highly efficient, and reusable heterogeneous catalytic system for the synthesis of symmetrical diaryl sulfoxides from the reaction of thionyl chloride and arenes. The catalyst is reusable.
