  Suzuki–Miyaura Cross-Coupling of Potassium Alkoxyethyltrifluoroborates: Access to Aryl/Heteroarylethyloxy Motifs

  摘要：

  The introduction of an alkoxyethyl moiety onto aromatic substructures has remained a long-standing challenge for synthetic organic chemists. The main reasons are the inherent instability of alkoxyethylmetallic species and the lack of general procedures to access them. A new method utilizing a cross-coupling strategy based on the exceptional properties of organotrifluoroborates has been developed, and the method allows an easy and efficient installation of this unit on a broad range of aryl and heteroaryl bromides.

• Nickel/Photoredox Dual Catalytic Cross-Coupling of Alkyl and Amidyl Radicals to Construct C(sp³)–N Bonds

  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。
