Cationic complexes PF4(N-N)+, where N-N = 2,2′-bipyridine (bpy), 4-fluoro-2,2′-bipyridine (fbpy), and 1,10-phenanthroline (phen), were prepared in modest yield and identified by their A2B2 and A2BC fluorine NMR spectra, which are similar to those of the isoelectronic SiF4(N-N) adducts. The ligands bpy, fbpy, and phen may be useful for monitoring reactions of HF and H2O, or other fluorinated compounds, with glass apparatus because any liberated SiF4 is then trapped as SiF4(N-N), which can be readily detected by NMR spectroscopy.
