956, (1 11 3) Capital Federal, Argentina The electron impact mass spectral fragmentation of a series of 3-substituted-1,2,3,4-tetrahydroisoquinolinc~ are reported. The principal fragmentation modes of these compounds comply with the main generalizations reacbed earlier with simpler systems. Complet
## Abstract The mass spectra of eight pyrrolo[1,2‐__a__][1,3,5]triazie‐2,4(1__H__, 3__H__)‐diones have been examined. An unusual feature in the fragmentation of those compounds having a 7‐alkoxycarbonyl function, namely loss of the whole ester grouping with concomitant hydrogen rearrangement, is di
