Ethynamine (HO≡CNH) has been prepared from three different precursors (7a, 7b, and 8) by flash vacuum pyrolysis and observed by low-temperature infrared spectroscopy for the first time. The collision activation mass spectra (CAMS) strongly support the assignments. The Meldrum'sacidderivative 8 also gives rise to equilibrating imidoylketene (10) and aminopropadienone (9), observable by both IR and
