The mass spectral retro Diels ‐ Alder ‐reaction: 1,2,3,4‐tetrahydrocarbazole 1,2,3,4‐Tetrahydrocarbazole undergoes a retro Diels ‐ Alder ‐reaction under electron impact. C(2) and C(3) are eliminated as ethylene. This is shown by measuring the deuterated derivatives 1a , 1b and 1c . Furthermore the oxo‐1,2,3,4‐tetrahydrocarbazole derivatives 3 and 4 are investigated in respect to the mass spectral retro Diels ‐ Alder reaction too.
