AI Article Synopsis
- The study focused on the conversion of aromatic 14π tetraaryl triphyrin(2.1.1) compounds into stable antiaromatic 16π P(V) complexes by refluxing them with phosphorus chloride (PCl) in a mixed solvent of toluene and triethylamine.
- Characterization of the resultant P(V) triphyrin(2.1.1)s was accomplished using high-resolution mass spectrometry (HRMS) and nuclear magnetic resonance (NMR) spectroscopy.
- The research further explored their properties through absorption, electrochemical methods, and density functional theory (DFT), revealing that PCl effectively transforms 14π triphyrins into 16π forms, leading to the formation of stable antiar
Article Abstract
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.
