  Oxidation of Organotrifluoroborates via Oxone

  摘要：

  A method for the oxidation of organotrifluoroborates using Oxone was developed. A variety of aryl-, heteroaryl-, alkenyl-, and alkyltrifluoroborates were converted into the corresponding oxidized products in excellent yields. This method proved to be tolerant of a broad range of functional groups, and in secondary alkyl substrates it was demonstrated to be completely stereospecific.

  An efficient enantioselective addition of alkyl radicals, oxidatively generated from organotrifluoroborates, to acceptor-substituted alkenes is catalyzed by a bis-cyclometalated rhodium catalyst (4 mol %) under photoredox conditions. The practical method provides yields up to 97% with excellent enantioselectivities up to 99% ee and can be classified as a redox neutral, electron-transfer-catalyzed reaction

  作者：Shaofang Zhou、Kang Lv、Rui Fu、Changlei Zhu、Xiaoguang Bao

  DOI：10.1021/acscatal.1c00731

  日期：2021.5.7

  The construction of C(sp3)–N bonds via direct radical–radical cross-coupling under benign conditions is a desirable but challenging approach. Herein, the cross-coupling of alkyl and amidyl radicals to build aliphatic C–N bonds in a concise, mild, and oxidant-free manner is implemented by nickel/photoredox dual catalysis. In this protocol, the single electron transfer strategy is successfully employed

  在良性条件下通过直接自由基-自由基交叉偶联来构建C（sp 3）-N键是一种理想但具有挑战性的方法。在此，通过镍/光氧化还原双重催化，以简明，温和且无氧化剂的方式将烷基和and基自由基交叉偶联以建立脂族C–N键。在该协议中，成功地采用了单电子转移策略，分别从磺酰基叠氮化物/叠氮基甲酸酯和烷基三氟硼酸酯生成N-和C-中心的自由基。然而，光催化剂诱导的三重态-三重态能量转移机制可能不适用于该反应。激发的光催化剂（Ru II / * Ru II / Ru III / Ru II的氧化猝灭途径））结合可能的Ni I / Ni II / Ni III / Ni I催化循环，基于协同实验和计算研究，提出了镍/光氧化还原双催化C（sp 3）–N键形成的方法。
