Herein we report ketones as feedstock materials in radical cross-coupling reactions under Ni/photoredox dual catalysis. In this approach, simple condensation first converts ketones into prearomatic intermediates that then act as activated radical sources for cross-coupling with aryl halides. Our strategy enables the direct benzylation/benzoylation of (hetero)arenes under mild reaction conditions with high functional group tolerance.

Paragraph 0051, (2017/01/12)
The invention discloses a method for preparing diaryl ketone from aryl sulfonate. The method includes following steps: in the presence of a catalyst and carbon monoxide, allowing aryl sulfonate and aryl boronic acid to react in an organic solvent; after reaction is finished, performing aftertreatment to obtain diaryl ketone. Aryl sufonate is adopted as an electrophilic reagent for Suzuki cross carbonylation coupling reaction, diaryl ketone is directly synthesized through carbon monoxide, aryl sulfonate and aryl boronic acid, reaction conditions are milk, functional groups are high in tolerance, a substrate is cheap and easy to get, and diaryl ketone can be prepared with high yield.
