Abstract
Difluorocyanamin, F2NCN, does not react with the superacids XF/MF5 (X = H, D; M = As, Sb) under formation of protonated nitrilium salts. At -78 degrees C iminium salts of the general form F2NC(F)NX2+MF6- are ob served, which are characterized by vibrational and nmr spectroscopy. T he structure and vibrational frequencies were computed ab initio at th e Hartree-Fock (HF/6-31 + G) and correlated Moller-Plesset (MP2/6-31 + G) levels of theory.
