要旨:
Adamentene (2), the “anti-Bredt compound” par excellence, has formerly only been detected by trapping experiments. It has now been generated as the neutral molecule in the mass spectrometer by unimolecular fragmentation of the radical cation (1), R=H or D, at ca. 10−6 torr. This observation was confirmed by comparison with the decomposition of the tert-butyl and cyclohexyl analogs of (1) and by peak shape analyses.
