The aromatic 14π -tetraaryl triphyrin(2.1.1)s were switched to stable antiaromatic 16π P(V) complexes of triphyrin(2.1.1) by refluxing free base triphyrin(2.1.1)s with PCl in a mixture of solvents toluene/triethylamine for 4 h. The P(V) triphyrin(2.1.1)s were characterized by high-resolution mass spectrometry (HRMS) and nuclear magnetic resonance (NMR) spectroscopy and their properties were studied in detail by absorption, electrochemical, and density functional theory (DFT) studies. The studies suggested that PCl reduces 14π triphyrins to 16π triphyrins, which were then complexed to form stable antiaromatic P(V) complexes.
通过将游离碱三卟啉（2.1.1）与五氯化磷在甲苯/三乙胺混合溶剂中回流4小时，将芳香性14π - 四芳基三卟啉（2.1.1）转变为稳定的反芳香性16π 五价磷（P(V)）三卟啉（2.1.1）配合物。通过高分辨率质谱（HRMS）和核磁共振（NMR）光谱对五价磷（P(V)）三卟啉（2.1.1）进行了表征，并通过吸收、电化学和密度泛函理论（DFT）研究详细研究了它们的性质。研究表明，五氯化磷将14π 三卟啉还原为16π 三卟啉，然后这些三卟啉络合形成稳定的反芳香性五价磷（P(V)）配合物。
