The imidic acids HNC(H)OH and CH3NC(H)OH and their tautomeric carbenes H2N7z.sbnd;C̈OH and CH3N(H)C̈OH: stable species in the gas phase formed by one-electron reduction of their cations

The prototype imidic acid, formimidic acid, HNC(H)OH, 2, as well as aminohydroxy-carbene, 3, both isomeric with formamide, 1, have been generated in the gas phase by one-electron reduction of the corresponding radical cations. The ionic precursors 2+ and 3+ were produced by appropriate dissociative ionizations, whereas 1+ was formed by direct ionization of formamide. From a detailed analysis of collision induced dissociation (CID) mass …
