  摘要：

  在CuI-2,2'-联吡啶和Zn的存在下，芳基二硫代氨基甲酸酯和芳基重氮盐的CS交叉偶联已开发出一种有效的合成不对称二芳基硫醚的方法。芳基二硫代氨基甲酸酯化合物在这里已被用作硫醇的替代物。该方案显示出较宽的底物范围和良好的产品收率。

  Pd-Catalyzed carbon–sulfur cross-coupling reactions of aryl chlorides with indium tris(organothiolates) were developed. Aryl chlorides reacted with indium tris(organothiolates) (0.35 equiv) in the presence of 4 mol % of Pd(OAc)2, 4.2 mol % of Xantphos, and Cs2CO3 as an additive, producing aryl–aryl and aryl–alkyl sulfides in good to excellent yields.

  requirement of higher reaction temperatures for an SNAr reaction between thiols and less reactive electron-poor aryl halides described in earlier reports has triggered intensive studies on the development of metal- and photo-catalyzed methods to promote this transformation. We report here that an SNAr reaction of thiols with most electron-poor aryl halides takes place at RT–60 °C under the action of

  早期报道中描述的硫醇和反应性较低的缺电子芳基卤化物之间的S N Ar 反应需要更高的反应温度，这引发了对开发金属和光催化方法以促进这种转变的深入研究。我们在此报告，在 K 2 CO 3和 DMAc的作用下，硫醇与大多数缺电子芳基卤化物在 RT–60 °C 下发生S N Ar 反应。在这种温和的条件下，碱和溶剂都起着至关重要的作用。对于对 S N不发生反应的（杂）芳基卤化物Ar反应中，鉴定出两种更强大的草酸二酰胺配体，使其Cu催化的偶联反应能够在低催化负载量下进行。这两种方法的结合为制备（杂）芳基硫醚提供了一种非常有吸引力的方法。
• Synthesis of Diaryl Ethers, Diaryl Thioethers, and Diarylamines Mediated by Potassium Fluoride−Alumina and 18-Crown-6:  Expansion of Scope and Utility¹

  An efficient alternative to the Ullmann ether synthesis of diaryl ethers, diaryl thioethers, and diarylamines involving the SNAr addition of a phenol, thiophenol, or aniline to an appropriate aryl halide, mediated by potassium-fluoride alumina and 18-crown-6 in acetonitrile or DMSO, is described. Expansion of the reaction conditions to include DMSO as solvent has resulted in a far greater range of substitution patterns permitted on the electrophile. For example, it was found that electronically unfavorable S-chlorobenzonitrile could be condensed with 3-methoxyphenol to form the corresponding diaryl ether in 66% yield, a combination not normally amenable to Ullmann coupling. Electron-withdrawing groups present on the electrophile may be as diverse as nitro, cyano, formyl, acetyl, ester, amide, and even aryl. The method features a simple reaction procedure that provides products in generally good to excellent purified yields.
