  Conformations of Bridged Diphenyls. V. A Nuclear Magnetic Resonance Comparative Study of the Conformations of Identically Substituted Diphenyl Ethers, Sulfides, Methanes, Ketones, Sulfoxides, and Sulfones

  摘要：

  使用在之前的论文中发展的核磁共振方法，比较了两个系列的构象，一个是双邻位取代的，另一个是三邻位取代的，这两个系列都是六个相同取代的桥联二苯基化合物。已经证明醚类化合物、硫醚和甲烷在构象上是相同的，其中二邻位取代的环垂直于中央桥平面，而另一个环位于该平面上，一个邻位氢原子占据“内部”或“近端”位置。苯甲酮和亚砜更倾向于采取一个构象，其中每个环与中央平面之间的二面角约为40-50°，一个邻位氢原子占据“外部”或“远端”位置。砜类化合物采取了两个环更接近垂直于中央平面的构象。

  We report a novel strategy to prepare valuable nitriles and ketones through the conversion of esters under metal-free conditions. By using the I2/PCl3 system, various substrates including aliphatic and aromatic esters could react with acetonitrile and arenes to afford the desired products in good to excellent yields. This method is compatible with a number of functional groups and provides a simple

  我们报告了一种通过在无金属条件下转化酯来制备有价值的腈和酮的新策略。通过使用I 2 / PCl 3系统，包括脂肪族和芳香族酯在内的各种底物可以与乙腈和芳烃反应，以良好或极好的收率提供所需的产物。该方法与许多官能团相容，并为腈化合物和芳基酮的合成提供了一种简单而实用的方法。

  Using n.m.r. methods developed in earlier papers, the conformations of two series, one doubly ortho-substituted and one triply ortho-substituted, of six identically substituted bridged diphenyls were compared. The ethers, sulfides, and methanes have been shown to adopt the same conformation in which the di-ortho-substituted ring is perpendicular to the central bridge plane while the other ring lies in that plane and an ortho hydrogen takes up the "inside" or "proximal" position. The benzophenones and sulfoxides prefer a conformation in which the dihedral angle between each ring and the central plane is about 40–50° and an ortho hydrogen adopts the "outside" or "distal" position. The sulfones adopt a conformation in which the two rings are more nearly perpendicular to the central plane.

  The Friedel-Crafts acylation reaction between activated amides and arenes was carried out by employing [Pd(cinnamyl)Cl]2 and Cu(OTf)2 as catalysts. A range of N-phenyl-N-tosylbenzamides, which were substituted at the phenyl ring of the benzamide moiety, underwent reaction with various arenes, such as mesitylene, toluene, anisole, 4-tert-butylbenzene, o-xylene, m-xylene, and p-xylene, affording the
