An electron donor–acceptor (EDA) complex photoactivation strategy for radical fluorosulfonylation is disclosed for the first time. Simply upon blue light irradiation, the FSO2 radical can be generated efficiently under catalyst-free, base-free, and additive-free conditions, which enables facile access to 6-keto alkenylsulfonyl fluorides from readily available propargyl alcohols and FSO2Cl. The 6-keto
首次公开了用于自由基氟磺酰化的电子供体-受体 (EDA) 复合物光活化策略。简单地在蓝光照射下,FSO 2自由基可以在无催化剂、无碱和无添加剂的条件下有效地产生,这使得能够容易地从容易获得的炔丙醇和FSO 2 Cl获得6-酮基烯基磺酰氟。6-酮基烯基磺酰氟基序已被展示为具有多种后续衍生化的多功能 SuFEx 中心。
