Abstract

Successive reactions of pentafluoronitrobenzene with resorcinol, orcinol, and tetrafluororesorcinol in acetonitrile in the presence of triethylamine afforded polyfluorinated ABAB and ABAC tetraoxacalix[4]arenes. Analysis of the¹H and ¹⁹F NMR spectra of the synthesized oxacalixarenes indicated high conformational mobility of the resorcinol and tetrafluororesorcinol fragments of their molecules due to interaction with the solvent.

五氟硝基苯与间苯二酚，间苯二酚和四氟间苯二酚的反应合成多氟四氧杂四环[4]芳烃

摘要

在三乙胺的存在下，五氟硝基苯与间苯二酚，间苯二酚和四氟间苯二酚在乙腈中连续反应，得到了多氟代ABAB和ABAC四恶唑[4]芳烃。合成的氧杂芳烃的¹ H和¹⁹ F NMR光谱分析表明，由于与溶剂的相互作用，间苯二酚和四氟间苯二酚片段的分子具有很高的构象迁移率。
