Notes:
Heterocumulenes such as ketenes, propadienones and comulogs of isocyanates are produced by flash vacuum pyrolysis of Meldrum's acid. Real-time monitoring of the pyrolysis products is performed by methods of tandem mass spectrometry. In particular, chemical ionization is show, for the first time, to generate protonated moleculular ions of these kinetically unstable neutral molecules which can be identified by collisional activation experiments.
