obtained via Cu-assisted reductiveamination of the ortho-2-pyridylarylboronic acids. Comparative analysis of the spectral and electrochemical data obtained for new diarylamines and their pyridyl-free counterparts revealed the intramolecular H-bond (IMHB) formation which significantly influences the properties of the amino group. The electron density at the N atom of the amino group is increased due
通过邻-2-吡啶基芳基硼酸的Cu辅助还原胺化获得新的含吡啶基的二芳胺。对新二芳基胺及其无吡啶基对应物获得的光谱和电化学数据的比较分析揭示了分子内 H 键 (IMHB) 的形成,这显着影响了氨基的性质。由于 N-H 键的部分弱化,氨基的 N 原子处的电子密度增加,尽管 BDE 和 H 原子提取的活化能由于两个 N 原子的螯合作用而增加。与不含吡啶基的对应物相比,含邻吡啶基的二芳基胺更容易被氧化;氧化电位值的变化与分子内氢键的强度相关,可以通过在吡啶基或苯环中插入取代基来调节。即使在具有显着 H 受体能力的极性溶剂(如 DMSO)中,IMHB 也保留,但可以在甲醇中被破坏,证明有利于 H 键的动态性质。

synthesis and optoelectronic properties of five donor–acceptor molecules, featuring an electron-acceptor unit made of six fused benzenoid rings that resembles an equilateral triangle, are described. These molecular ‘triangles’ were synthesized in eight steps from simple building blocks such that the electron-donor substituents could be installed in the last step by means of the Suzuki cross-coupling

[N−I−N]+ halogenbond. We studied the importance of chelation, strain, steric hindrance and electrostatic interaction for the structure and reactivity of halogen bonded halonium ions by acquiring their 15N NMR coordination shifts and measuring their iodenium release rates, and interpreted the data with the support of DFT computations. A bidentate ligand stabilizes the [N−I−N]+ halogenbond, decreasing
[双(吡啶)碘(I)] +复合物在温和条件下提供对卤离子的受控访问。这种稳定的卤离子的反应性主要取决于它们的三中心、四电子 [NI-I-N] +卤素键。我们通过获取卤素键合卤离子的15 N NMR 配位位移和测量它们的碘释放速率,研究了螯合、应变、空间位阻和静电相互作用对卤素键合卤离子的结构和反应性的重要性,并在 DFT 计算的支持下解释了数据。双齿配体稳定 [N-I-N] +卤素键,降低铪转移率。应变削弱了键合并相应地增加了释放速率。只要效果是完全立体的,主链中的远程修饰就不会影响稳定性。在 [ NI -I-N] +基序附近结合富电子部分可提高碘释放速率。碘 (I) 转移机制的分析突出了二次相互作用的影响,并可能为亲电卤化中立体选择性的诱导提供一个解决方案。
