The fragmentation of aza-crown and diaza-crown ethers under electron impact was studied. It is shown that for the former the primary pathways of fragmentation of the molecular ions involve the intracyclic migration of a hydrogen atom and the elimination of C2H3O and CH2OH particles. A characteristic feature of the diaza-crown ethers is the ejection of a divinylaminyl radical.
