Neutralization‐reionization mass spectrometry of silaanthracene radical cations, which are generated from the 9,10‐dihydro‐9‐silaanthracenes 1, 3, 8 and 11 under electron‐impact conditions, indicates that silaanthracenes are stable molecues in the gas phase. Flash pyrolysis of the starting compounds mentioned above also yields the silaanthracenes 2, 4 , and 10 , which may be isolated in an argon matrix at 15 K and exhibit characteristic UV spectra.
