Photoelectron spectra of the aminodifluoroboranes NH₂BF₂, NHMeBF₂, and NMe₂BF₂

Photoelectron spectra of the aminodifluoroboranes NH₂BF₂, NHMeBF₂, and NMe₂BF₂ have been recorded. The results are discussed and compared with theoretical calculations. The first ionization potentials of NH₂BF₂, NHMeBF₂, and NMe₂BF₂ are 11.47, 10.45, and 9.49 eV respectively. The study shows that BF₃ reacts with NH₃, NH₂Me, and NHMe₂ to form solid products which on vaporisation yield species resulting from the elimination of HF from the classical donor-acceptor complexes NH₃BF₃, NH₂MeBF₃, and NHMe₂BF₃ respectively.
