摘要：

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