  coupling partners, including allylic carboxylates, aryl and vinyl electrophiles, and primary alkyl chlorides/bromides, making the method complementary to the cross-coupling procedures. The method is highly selective for the alkylation of tertiary alcohols, leaving secondary/primary alcohols (benzyl alcohols included) and phenols intact. The synthetic utility of the method is highlighted by its 10-gram-scale

  醇的脱氧自由基 CC 键形成反应是合成化学中长期存在的挑战，目前的方法依赖于多步骤程序。在此，我们报告了叔醇的直接脱羟基自由基烷基化反应。这一新协议显示了从醇类中生成叔碳自由基的可行性，并为轻松精确地构建全碳四元中心提供了一种方法。该反应在醇和活化烯烃的广泛底物范围内进行。它可以耐受各种亲电偶联伙伴，包括烯丙基羧酸盐、芳基和乙烯基亲电试剂以及伯烷基氯/溴化物，使该方法与交叉偶联程序形成互补。该方法对叔醇的烷基化具有高度选择性，保持仲醇/伯醇（包括苯甲醇）和酚类完好无损。该方法的合成效用因其 10 克规模的反应和复杂分子的后期修饰而突出。实验和 DFT 计算的组合建立了一个合理的机制，暗示通过 Ti 催化的 C-OH 键均裂产生叔碳自由基。
