Notes:
Recent theoretical and experimental studies are in conflict with our previous neutralization-reionization evidence for the surprising stability of simple ylides such as H2CCIH. Neutralization of [H2CCIH]+· ions from CICH2COOH with Hg followed by reionization of the resulting neutral molecules with O2 produces intense [CCIH3]+· parent ions. Collisionally activated dissociation of these mass-selected ions shows that 47 ± 5% are the [H2CCIH]+· isomer. This demonstrates that stable H2CCIH molecules can be formed by neutralization, surviving intact for the lifetime of the experiment (10-6 s). Field ionization conditions effective in ionizing excited argon atoms do not produce appreciable ionization of the neutrals from [H2CCIH]+·, suggesting that the stable H2CCIH neutrals are not Rydberg state molecules.
