  explored. The results of this effort have led to the identification of several key factors that govern the chemoselectivities and efficiencies of the competitive reaction pathways followed. The observations suggest that the length and nature of the chain linking the phthalimide acceptor and α-silyl donor sites are important factors in controlling the rates of formation of zwitterionic biradicals that serve

  通过使用由邻苯二甲酰亚胺受体组成的系统，通过邻苯二甲酰亚胺受体通过聚亚甲基或聚乙氧基链连接到α-甲硅烷基醚和硫醚供体上，探索了控制SET促进的受体-多供体底物光环化反应的化学选择性和效率的因素。制备了许多这种类型的线性和支化底物，并研究了它们的光化学行为。这项工作的结果导致确定了几个关键因素，这些关键因素决定了随后竞争反应途径的化学选择性和效率。观察结果表明，连接邻苯二甲酰亚胺受体和α-甲硅烷基供体位点的链的长度和性质是控制两性离子双自由基形成速率的重要因素，该两性离子双自由基在产物形成途径中是倒数第二个中间体。此外，在中间两性离子双基自由基中，甲醇在阳离子自由基中心促进的脱甲硅基化反应的速率也起着重要作用，尤其是在链长/类型不重要的情况下。就其机理和综合意义进行了讨论。
• Copper‐Catalyzed Borylative Methylation of Alkyl Iodides with CO as the C1 Source: Advantaged by Faster Reaction of CuH over CuBpin

  the same reaction is still rarely reported due to their high reactivity. Now, a study on CuH‐ and CuBpin‐catalyzed borylative methylation of alkyl iodides with CO as the C1 source is reported. Various one carbon prolongated alkyl boranes (RCH2Bpin and RCH(Bpin)2) were produced in moderate to good yields from the corresponding alkyl iodides (RI). In this cooperative system, CuH reacts with alkyl iodide

  CuH和CuBpin是有机化学中的多功能催化剂和中间体。但是，由于CuH和CuBpin具有高反应活性，因此很少涉及将CuH和CuBpin参与同一反应的研究。现在，已有关于使用CO作为C1源的CuH和CuBpin催化的烷基碘化物的硼化甲基化研究的报道。从相应的烷基碘（RI）以中等至良好的产率制备了各种一碳延长的烷基硼烷（RCH 2 Bpin和RCH（Bpin）2）。在这种协作系统中，CuH与烷基碘的反应比CuBpin更快。
