Mass Spectrometry of 2a,4-Disubstituted 5-Benzoyl-2a,3,4,5-tetrahydro-2-phenoxy-azeto[1,2-a][1,5]benzodiazepin-1(2H)-one
The mass spectrometric fragmentation of 2a,4-disubstituted 5-benzoyl-2a,3,4,5-tetrahydro-2-phenoxy-azeto[1,2-a][1,5]benzodiazepin-1(2H)-ones has been investigated by means of mass-analyzed ion kinetic energy spectrometry under electron impact ionization conditions. All compounds tend to lose different moieties, such as phenoxy, phenoxy and H, and phenoxyketene. Both [M+-PhO] and [M+-PhOH] ions could further lose CO, and the [M+-PhOCH=C=O] ions could lose propene or styrene, PhCON, PhCOHN, and other fragments.
