  摘要：

  聚甲基氢硅氧烷（PMHS）与CsF的结合有助于炔烃或苯并噻唑与一系列乙烯基，苯乙烯基和芳基卤化物或壬二酸酯以及酰基氯的交叉偶联。实验和光谱证据表明，这些反应涉及甲硅烷氧基中间体的原位生成。这些交叉偶联在室温和无胺条件下进行得相对较快。为了证明该方法的适用性，进行了全细胞毒性丁醇内酯（-）-可可内酯A的合成。

• Polymethylhydrosiloxane (PMHS) as an Additive in Sonogashira Reactions
  作者：Robert E. Maleczka Jr.、William P. Gallagher

  DOI：10.1055/s-2003-37522

  日期：——

  Polymethylhydrosiloxane (PMHS) in combination with CsF facilitates the Sonogashira reaction of a variety of alkynes and electrophiles. These couplings appear to involve the in situ formation and reaction of an alkynylsiloxane. Such couplings can be run amine free at room temperature, reaction times are short, workup is easy, and product purification is straightforward. Thus, the advantages (and disadvantages) of running Sonogashira couplings with 1-silylalkynes are realized, without the need to preform the alkynyl silane.

  聚甲基氢硅氧烷（PMHS）与氟化铯（CsF）结合，促进了多种炔烃与电亲核试剂的索诺加希拉反应。这些偶联反应似乎涉及到原位形成和反应炔基硅氧烷。这些偶联反应可以在室温下无胺进行，反应时间短，后处理简单，产品纯化直观。因此，利用1-硅基炔烃进行索诺加希拉偶联反应的优点（和缺点）得以实现，而无需预先制备炔基硅烷。

  detailed study of the palladium-catalyzed amination of aryl nonaflates is reported. Use of ligands 2-4 and 6 allows for the catalytic amination of electron-rich and -neutral aryl nonaflates with both primary and secondary amines. With use of Xantphos 5, the catalytic amination of a variety of functionalized aryl nonaflates resulted in excellent yields of anilines; even 2-carboxymethyl aryl nonaflate is effectively

  报道了钯催化芳基壬二酸酯的胺化的详细研究。配体2-4和6的使用允许富电子的和-中性的芳基壬酸酯与伯胺和仲胺催化胺化。使用Xantphos 5时，各种功能化的芳基壬酸酯的催化胺化反应可产生优异的苯胺收率。甚至2-羧甲基芳基壬酸酯也可以有效地与伯烷基胺偶联。当将卤代芳基壬酸酯与多种胺偶联时，可获得中等产率，其中在大多数情况下，芳基壬酸酯相对于卤代芳基优先反应。总体而言，在钯催化的CN键形成过程中，壬酸芳基酯是三氟甲磺酸酯的有效替代物，因为它们在反应条件下具有更高的稳定性。

  coupling of aryl triflates and nonaflates with alkyl iodides using manganese(0) as a reductant is described. The method is applicable to the reductive alkylation of various aryl sulfonates, including o-borylaryl triflate, which enabled efficient construction of diverse alkylated arenes under mild conditions.

• A General Method for Palladium-Catalyzed Reactions of Primary Sulfonamides with Aryl Nonaflates

  日期：2011.6.3

  A general method for Pd-catalyzed sulfonamidation of aryl nonafluorobutanesulfonates (aryl nonaflates) is described. A biaryl phosphine ligand, t-BuXPhos, formed the most active catalyst, and K3PO4 in tert-amyl alcohol was found to be the optimal base solvent combination for the reaction. The reaction conditions were tolerant of various functional groups such as cyano, nitro, ester, aldehyde, ketone, chloride, carbamate, and phenol. Heterocyclic aryl nonaflates were found to be suitable coupling partners. High yields of the coupled products were obtained from the reactions between inherently disfavored substrates such as electron-rich nonaflates and electron-poor sulfonamides. Kinetic data suggest reductive elimination to be the rate-limiting step for the reaction. The only limitation of this methodology that we have identified is the inability of 2,6-disubstituted aryl nonaflates to efficiently participate in the reaction.
• One-Pot, Two-Step, Microwave-Assisted Palladium-Catalyzed Conversion of Aryl Alcohols to Aryl Fluorides via Aryl Nonaflates

  A convenient procedure for converting aryl alcohols to aryl fluorides via aryl nonafluorobutylsulfonates (ArONf) is presented. Moderate to good one-pot, two-step yields were achieved by this nonaflation and microwave-assisted, palladium-catalyzed fluorination sequence. The reductive elimination step was investigated by DFT calculations to compare fluorination with chlorination, proving a larger thermodynamic driving force for the aryl fluoride product. Finally, a key aryl fluoride intermediate for the synthesis of a potent HCV NS3 protease inhibitor was smoothly prepared with the novel protocol.
