Regioselective difunctionalization of alkenes has attracted significant attention from synthetic chemists and has the advantage of introducing diverse functional groups into vicinal carbons of common alkene moieties in a single operation. Herein, we report an unprecedented intermolecular atom transfer thiosulfonylation reaction of alkenes by combining gold catalysis and visible-light photoredox catalysis
烯烃的区域选择性双官能化引起了合成化学家的极大关注,并且具有在单一操作中将不同官能团引入常见烯烃部分的邻位碳的优点。在此,我们通过结合金催化和可见光光氧化还原催化,报道了前所未有的烯烃分子间原子转移硫代磺酰化反应。三氟甲硫基(SCF 3)和其他官能化硫基与磺酰基一起以最原子经济的方式区域选择性地引入到烯烃中。详细的机理研究表明,金催化和光氧化还原催化的协同组合对于该反应至关重要。
