ResumoThe ion [CH2NO2]− is a weak base, a poor nucleophile and a weak oxidising agent. It is unable to oxidise COS but does react with CS2 by the reaction [CH2NO2]− + CS2 → CS2O−· + [CH2NO]·. Deprotonated acetone oxime [Me2CNO]− is a moderate gas phase oxidising agent reacting with COS, CS2 and SO2 to yield CO2S−·, CS2O−· and SO−·3 respectively. ΔH∘acid of (CH3)2CNOMe is bracketted at 1560±15 kJ mol−1; the deprotonated species forms addition complexes with CO2, CS2, COS and SO2.
