Photoinduced rearrangement of vinyl tosylates to β-ketosulfones

We developed a photoinduced radical fragmentation and rearrangement of vinyl tosylates that enables efficient formation of β-ketosulfones. This process is based on the photoinitiated homolysis of vinyl tosylate to release a sulfinyl radical from the tosyl group and the subsequent addition of a sulfinyl radical to another vinyl tosylate to form the desired β-ketosulfones. This simple protocol features a broad scope with both aromatic and aliphatic substrates, convenient reagents and operating systems.

Method for efficiently synthesizing beta-ketone sulfonyl compounds through visible light induction

The invention provides a method for efficiently synthesizing beta-ketone sulfonyl compounds through visible light induction. The method specifically comprises steps as follows: in the presence of an organic solvent and at the room temperature, enol sulfonate compounds are taken as a raw material and react for 1-12 h through induction of visible light under the catalysis action of an organic compound serving as a photocatalyst, and the beta-ketone sulfonyl compounds are prepared. Compared with an existing method, the method has a wide applicable substrate range, a substrate is convenient and easy to obtain, reaction conditions are mild, operation is simple and convenient, the reaction efficiency is high, and the method has huge value in industrial application.
