Conclusions 1. Decomposition under the influence of electron impact of 2-organyl-1,2-azaborolines (I)–(XIII) occurs selectively, in the mass spectra an intense peak of the [M-R4]+ ion dominates, explained by the loss of the substituent from C3, the remaining ions usually do not exceed 10% of its intensity. 2. The boron-containing ring in the bicyclic compounds (III)–(XIII) is more stable to the influence of electron impact. 3. Fragmentation with rupture of the C-O bond in the alkyloxy group on the boron atom is characteristic for 2-alkoxy-1,2-azaborolines.
