It is shown by proton abstraction reactions in combination with deuterium labelling that the initial structure of the ions 1 – 3 generated by electron impact from some benzylideneamines through loss of an alkyl radical via α‐cleavage is indeed that of phenyl‐substituted 2‐azaallenium ions. The deprotonated species appear to have very high gas‐phase basicities, that are higher than 231.7 kcal/mol.
