During a comparison study of the fast atom bombardment (FAB) and electron impact mass spectra of 1‐organyl‐2,9,10‐trioxa‐6‐aza‐1‐silatricyclo[4.3.3.0 1,6 ]dodecanes, an unusual ion peak at m / z 164 was noticed in the FAB spectra. Accurate mass measurement indicated that m / z 164 corresponds to protonated 1‐[ N,N ‐bis(2‐hydroxyethyl)amino]‐1‐propanol (BHAP), which is produced by a ring‐rupture reaction. Further experiment showed that the intensity of the [BHAP + H] + ion peak increased markedly as the 7keV Ar 0 bombardment proceeded, suggesting a FAB‐induced reaction. The possible mechanism is also discussed.
