agrochemical applications. In this study, we present a visible light-mediated photoredox neutral strategy for the fluoroalkylation of tertiary alkyl chlorides under transition-metal-free conditions. This method allows for the facile synthesis of fluoroalkylated all-carbon quaternary centers, exhibiting excellent functional group compatibility. Mechanistic studies reveal the involvement of two reactive
全氟烷基在医药和农用化学品应用中变得非常重要。在这项研究中,我们提出了一种可见光介导的光氧化还原中性策略,用于在无过渡金属的条件下进行叔烷基氯的氟烷基化。该方法可以轻松合成氟烷基化的全碳四元中心,并表现出优异的官能团相容性。机理研究揭示了两种反应性自由基中间体的参与以及以自由基-极性交叉方式原位形成金属烯醇化物。该方法的多功能性通过基于羰基的合成转化得到证明,展示了其快速组装带有氟烷基全碳四元中心的多种有机分子的潜力。
