The electron impact fragmentation patterns of some 1-oxa-4-azabutadienes have been determined and supported by the corresponding metastables.The effect of substituents on this fragmentation has been investigated.Satisfactory correlation of intensity ratios of the peaks characterizing the primary fragmentation versus the Brown and Okamoto ?+ substituent parameters has been found.The relationship between the substituent parameters and the dissociation energy ED,C(3)-C(5), estimated with the help of appearance energies has been considered.
