Cationic complexes PF 4 (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 A 2 B 2 and A 2 BC fluorine NMR spectra, which are similar to those of the isoelectronic SiF 4 (N-N) adducts. The ligands bpy, fbpy, and phen may be useful for monitoring reactions of HF and H 2 O, or other fluorinated compounds, with glass apparatus because any liberated SiF 4 is then trapped as SiF 4 (N-N), which can be readily detected by NMR spectroscopy.
