  Diamination of Phenylene Dihalides Catalyzed by a Dicopper Complex

  摘要：

  Diamination of phenylene dihalides with aqueous ammonia to give the corresponding phenylenediamines can be achieved by using a dicopper complex [Cu-2(bpnp)(OH)(CF3COO)(3)] (1) (bpnp = 2,7-bis(pyridine-2-yl)-1,8-naphthyridine) as the catalyst in the presence of Bu4NBr and Cs2CO3 in high yields. In addition, 1,3,5-tribromobenzene was converted into benzenetriamine quantitatively under the same conditions. This method offers a new opportunity, particularly simplifying steps and increasing yields, for the preparation of aryl diamines.

  芳香族羧酸的无过渡金属脱羧溴化反应†

  摘要：

  在过去的一个世纪中，将脂肪酸转化为卤代烷的方法取得了显着进展，然而，芳香族酸的类似脱羧溴化仍然是一个长期的挑战。开发有效的芳基溴化物合成方法非常重要，因为它们是合成中的通用试剂，并且存在于许多功能分子中。在此，我们报告了芳香族酸的无过渡金属脱羧溴化反应。该反应适用于许多富含电子的芳族和杂芳族酸，这些酸先前已被证明是Hunsdiecker型反应的不良底物。此外，我们的初步机理研究表明，自由基中间体不参与该反应，这与经典的Hunsdiecker型反应性相反。全面的，

  Although iodine-catalyzed reaction has rapid advances in recent years, examples on iodine-catalyzed bromination are rare and the mechanism of these reactions remains unclear. Herein, we reported an I2-catalyzed aromatic bromination of aryl ethers by NBS and presented the details of the mechanistic study including kinetic study and the study of kinetic isotope effects. The study revealed that the reaction

  尽管近年来碘催化的反应发展迅速，但是碘催化溴化的例子很少，这些反应的机理尚不清楚。在本文中，我们报道了NBS的I 2催化的芳基醚的芳族溴化反应，并详细介绍了包括动力学研究和动力学同位素效应在内的机理研究。研究表明，该反应实际上是由诱导期形成的IBr催化的，而决定速率的步骤是在IBr辅助下消除Wheland中间体的HBr。

  trifluoromethylphenylene-bridged diphobane L1 with an electron-withdrawing substituent, lead to ester products via alkoxycarbonylation, whereas BCOPE gives predominantly alcohol products (n-nonanol and isomers) via reductive hydroformylation. The preference of BCOPE for reductive hydroformylation is also seen in the hydroformylation of 1-hexene in diglyme as the solvent, producing heptanol as the major product, whereas

  已经合成了具有不同取代基（CF 3、H、OMe、（OMe）2、t Bu）的亚苯基桥连二恶烷配体，并将其用作钯催化的各种烯烃羰基化反应中的配体。已经使用 1-己烯、1-辛烯和戊烯酸甲酯作为底物研究了这些配体在加氢甲酰化与烷氧基羰基化选择性方面的性能，并将结果与​​乙烯桥连二恶烷配体 ( BCOPE ) 进行了比较。1-辛烯在质子溶剂 2-乙基己醇中的加氢甲酰化导致加氢甲酰化和烷氧基羰基化之间的竞争，其中亚苯基桥连的配体，特别是三氟甲基亚苯基桥连的二恶烷L1带有吸电子取代基，通过烷氧基羰基化产生酯产物，而BCOPE通过还原加氢甲酰化产生主要的醇产物（正壬醇和异构体）。在以二甘醇二甲醚为溶剂的 1-己烯的加氢甲酰化中也可以看到BCOPE对还原加氢甲酰化的偏好，生成庚醇作为主要产物，而在这种情况下，亚苯基桥连的配体显示出低得多的活性。亚苯基桥连配体在 1-辛烯甲氧基羰基化生成壬酸甲酯方面表现出优异
