氟烷基和氟磺酰基均为生物活性分子中的重要结构单元, 同时也是有机合成中具有重要价值的功能基团. 报道了一种光氧化还原与钯协同催化的未活化烯烃氟烷基-氟磺酰化反应. 该方法以芳基三氟甲基化合物作为氟烷基自由基前体, 以1,4-二氮杂双环[2.2.2]辛烷-二氧化硫加合物(DABSO)为二氧化硫来源, N-氟代苯磺酰亚胺(NFSI)为氟源, 通过自由基二氧化硫插入氟化(RSIF)策略, 实现了碳碳双键的双官能团化转化. 在该反应中, 氟烷基和氟磺酰基能够一步同时引入到烯烃分子中, 从而高效构建结构多样的脂肪族磺酰氟化合物. 该反应条件温和, 具有良好的官能团兼容性. 此外, 所得磺酰氟产物可通过SuFEx点击反应进一步转化为多种高附加值化合物.

Both fluoroalkyl and fluorosulfonyl groups are important structural motifs in bioactive molecules and valuable functional units in synthetic chemistry. Herein, a photoredox-and palladium-dual-catalyzed fluoroalkylfluorosulfonylation of unactivated olefins was reported using aryl trifluoromethyl compounds as fluoroalkyl radical precursors, 1,4-diazabicyclo-[2.2.2]octane-bis(sulfur dioxide) adduct (DABSO) as the sulfur dioxide source, and N-fluorobenzenesulfonimide (NFSI) as the fluorine source via radical sulfur dioxide insertion and fluorination strategy. This transformation enables the simultaneous installation of fluoroalkyl and fluorosulfonyl groups across carbon-carbon double bonds in a single step, thus providing an efficient and concise approach to structurally diverse aliphatic sulfonyl fluorides. The reaction proceeds under mild conditions and exhibits good functional-group tolerance. Furthermore, the resulting sulfonyl fluoride products can be readily transformed into valuable compounds through SuFEx reactions.
