  Hydride, Hydrogen, Proton, and Electron Affinities of Imines and Their Reaction Intermediates in Acetonitrile and Construction of Thermodynamic Characteristic Graphs (TCGs) of Imines as a “Molecule ID Card”

  摘要：

  A series of 61 imines with various typical structures were synthesized, and the thermodynamic affinities (defined as enthalpy changes or redox potentials in this work) of the imines to abstract hydride anions, hydrogen atoms, and electrons, the thermodynamic affinities of the radical anions of the imines to abstract hydrogen atoms and protons, and the thermodynamic affinities of the hydrogen adducts of the imines to abstract electrons in acetonitrile were determined by using titration calorimetry and electrochemical methods. The pure heterolytic and homolytic dissociation energies of the C = N pi-bond in the imines were estimated. The polarity of the C = N double bond in the imines was examined using a linear free-energy relationship. The idea of a thermodynamic characteristic graph (TCG) of imines as an efficient "Molecule ID Card" was introduced. The TCG can be used to quantitatively diagnose and predict the characteristic chemical properties of imines and their various reaction intermediates as well as the reduction mechanism of the imines. The information disclosed in this work could not only supply a gap of thermodynamics for the chemistry of imines but also strongly promote the fast development of the applications of imines.

  the growing demand for green and sustainable chemical processes, the catalytic reductive alkylation of amines with main-group catalysts of low toxicity and molecular hydrogen as the reductant would be an ideal method to functionalize amines. However, such a process remains challenging. Herein, a novel reductive alkylation system using H2 is presented, which proceeds via a tandem reaction that involves

  鉴于对绿色和可持续化学过程的需求不断增长，以低毒主族催化剂和分子氢为还原剂的胺的催化还原烷基化将是一种理想的胺官能化方法。然而，这样的过程仍然具有挑战性。在此，提出了一种使用 H2 的新型还原性烷基化系统，该系统通过串联反应进行，该反应涉及 B(2,6-Cl2C6H3)(p-HC6F4)2 催化形成亚胺，随后通过沮丧的刘易斯对（FLP）。这种还原性烷基化反应产生 H2O 作为唯一的副产物，并直接将带有广泛取代基的胺官能化，这些取代基包括羧基、羟基、附加氨基、伯酰胺和伯磺酰胺基团。异吲哚啉酮和氨基邻苯二甲酸酐的合成也已通过一锅法实现，该法分别由本发明的还原烷基化与分子内酰胺化和分子内脱水反应的组合组成。该反应分别显示出对亚胺中间体和 B(2,6-Cl2C6H3)(p-HC6F4)2 浓度的零级和一级依赖性。此外，H2 浓度显着影响反应进程。这些结果表明了一种可能的机制，其中包含 THF 和 B(2

  solubility alone does not explain the performance of organic ionic bases in the room‐temperature coupling of aryl iodides and even bromides with aliphatic and aromatic amines and N‐heterocycles (NuH; see scheme). Conductivity measurements show that these organic ionic bases, which contain tetraalkylammonium or ‐phosphonium cations, are readily ionized in organic solvents.

  仅仅良好的溶解度并不能解释有机离子碱在芳基碘化物甚至溴化物与脂族和芳族胺以及N杂环的室温偶联中的性能（NuH；参见方案）。电导率测量表明，这些含有四烷基铵或阳离子的有机离子碱在有机溶剂中很容易被电离。

  Aldehydes and ketones were reductively aminated by a one‐pot procedure using a recyclable iron‐based Lewis catalyst, Aquivion‐Fe, to promote imine formation, and NaBH4 as reductant in cyclopentyl methyl ether and methanol. The developed protocol was successfully applied to the preparation of Cinacalcet, an important active pharmaceutical ingredient.
