Abstract

An environmentally friendly and practical method for the synthesis of various vinyl sulfones was developed through the direct sulfonylation of alkenyl sulfonium salts with sulfinic acids. The reaction was effectively triggered by the combined actions of milling, sunlight, and photocatalysts under solvent-free conditions, offering advantages such as a short reaction time (5-10 min), room temperature, and a straightforward workup procedure. Preliminary mechanistic studies suggested that a sulfonyl radical may be involved in this mechanophotocatalytic transformation process.
