摘要

通过烯基锍盐与亚磺酸的直接磺化反应，开发出了一种合成各种乙烯基砜的环保实用方法。在无溶剂条件下，研磨、阳光和光催化剂的联合作用有效地引发了该反应，具有反应时间短（5-10 分钟）、室温和操作简单等优点。初步机理研究表明，磺酰基自由基可能参与了这一机械光催化转化过程。

Manual Grinding and Sunlight Synergistically Promoted Sulfonylation of Alkenyl Sulfonium Salts with Sulfinic Acids

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.
