strategy has been established for the synthesis of β‐oxo sulfones via visible light‐induced oxysulfonylation of alkenes with arylazo sulfones with dioxygen in air. The present photoinduced transformation proceeds smoothly at room temperature in the absence of an external photosensitizer, which not only provides a mild and efficient approach to various β‐oxo sulfones, but also opens a different reaction
建立了一种无催化剂的策略,用于在空气中通过可见光诱导烯烃与芳基偶氮砜和双氧的氧磺酰化反应来合成β-氧代砜。在没有外部光敏剂的情况下,当前的光诱导转变在室温下平稳进行,这不仅为各种β-氧代砜提供了温和而有效的方法,而且为芳基偶氮砜的光化学反应开辟了不同的反应模式。
