Abstract
Conclusion In summary, we have shown that the methanimine anion (2) can readily be generated from (trimethylsily1) methyl azide in the gas phase presumably through the azidomethide ion. Ion 2 was found to have an acidity of 388 f 5 kcal/mol and an electron affinity of approximately 0.5 f 0.1 eV, both of which are in accord with a recent calculation. The methanimine anion was also found to react with a variety of reagents. In particular, it ...
