  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.

  Reductive amination of various ketones and aldehydes by transfer hydrogenation under aqueous conditions has been developed, by using cyclometallated iridium complexes as catalysts and formate as hydrogen source. The pH value of the solution is shown to be critical for a high catalytic chemoselectivity and activity, with the best pH value being 4.8. In comparison with that in organic solvents, the reductive

  通过使用环金属化的铱络合物作为催化剂，甲酸盐作为氢源，开发了在水性条件下通过转移氢化进行各种酮和醛的还原胺化反应。溶液的pH值对于高催化化学选择性和活性至关重要，最佳pH值为4.8。与有机溶剂相比，水相中的还原胺化速度更快，并且底物与催化剂的摩尔比（S / C）可设置为高达1×10 5。，是还原胺化反应中报道的最高S / C值。该催化剂易于获得，反应操作简单，可以使各种酮和醛与各种胺高产率地反应。该方案为合成胺化合物提供了一种实用且环保的新方法。

  series of chelating NHC–palladium complexes with different alkane-bridges of the type Pd[NHC–(CH2)n–NHC]X2 (X = Br or Cl, n = 2–4) were synthesized, where NHC is a triazolyl-N-heterocyclic carbene donor ligand. The bromide complexes with n = 2 and 3 were characterized by X-ray crystallography.
