In the context of studies on bis(dialkylamino)arenes with neighbouring amino functions the title compounds 5 and 6 were synthesized. Their structures and those of the monoprotonated cations 5a and 6a were determined by X-ray analysis. The strong basicities of 5 and 6 (pKa = 11.9 and 11.8 ± 0.1) are discussed in terms of lone pair interactions in 5 and 6 and the geometry of the N⋯H⋯N hydrogen bonds
在对具有相邻氨基官能团的双(二烷基氨基)芳烃的研究中,合成了标题化合物5和6。通过X射线分析确定它们的结构以及单质子化阳离子5a和6a的结构。的图5和6的强碱度(PK一个= 11.9和11.8±0.1)在5和6中的孤对电子的相互作用和在N⋯ħ⋯Ñ氢键的几何形状方面进行了讨论图5a和6a中。
