Darstellung von N-Methyl-N-chlornitryl-hexafluorometallaten ON(Cl)CH3+MF6− (M = As,Sb)

Preparation of N-Methyl-N-chlornitryl Hexafluoro Metallates ON(Cl)CH₃⁺MF₆^? (M = As, Sb) . The preparation of ON(Cl)CH₃⁺MF₆^? (M = As, Sb) by methylation of ONCl with CH₃OSO⁺MF₆^? (M = As, Sb) is reported. Both salts were unlimited stable at - 78°C. The nitryl cation which is isoelectronic with acetyl chloride was identified by vibrational spectroscopy as N-chloro-N-hydroxy-methaneiminium cation in the solid state.
