Conclusions

  1. 1.

    The stability of the molecular ion and fragmentation of 2-organylamino- and 2-organyloxy-1-propyl-1,2-azaborolidines is determined by the nature of the R substituent in the NHR and OR groups on the boron atom. The main fragmentation process is β-rupture in the alkyl substituent on the endocyclic nitrogen atom.

     
  2. 2.

    Alkylamino groups on the boron atom stabilize the boron-containing ring. The alkoxy group destabilizes the boron-containing ring, facilitating its decomposition under electron impact.

     
  3. 3.

    A method is proposed for recording mass spectra of compounds unstable toward oxygen and moisture in air.
