  Anion−π Interactions: Generality, Binding Strength, and Structure

  摘要：

  Anion-pi interactions have been systematically studied using tetraoxacalix[2]arene[2]triazine 1, an electron-deficient and cavity self-tunable macrocyclic host, as an electron-neutral molecular probe. As revealed by electrospray ionization mass spectrometry (ESI-MS), fluorescence titration and X-ray crystallography, tetraoxacalix[2]arene[2]triazine has been found to form 1:1 complexes with four typical polyatomic anions of different geometries and shapes in the gaseous phase, in solution, and in the solid state. The association constants for the formation of anion-pi complexes in acetonitrile are in the range of 239 to 16950 M-1, following the order of 1 center dot NO3- > 1.BF4- > 1.PF6- > 1.SCN-. X-ray molecular structures of the complexes showed that two opposing triazine rings of tetraoxacalix[2]arene[2]triazine act as a pair of tweezers to interact with the included anions through cooperative anion-pi and lone-pair electron-g interactions. The generality of anion-pi interactions and diverse anion-pi interaction motifs can provide a new dimension in the study of molecular recognition and self-assembly. Moreover, this study potentiates the effect of anion-pi interactions in chemical and biological systems, especially those involving anion and electron-deficient aromatic species.

  摘要：

  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。
