  Fragmentation of enamides derived from 6,7-dimethoxy-4-methyl-2H-1,3-benzothiazin and 3,4-dihydro-6,7-dimethoxy-1-methylixopuinoline

  摘要：

  AbstractThe electron impact mass spectra of several enamides have been examined. The enamides were prepared by reaction of aroyl halides with 6,7‐dimethoxy‐4‐methyl‐1,3‐benzothiazin, and with 3,4‐dihydro‐6,7‐dimethoxy‐l‐methylisoquinoline. The fragmentation pathways that have been proposed are supported by ion composition determinations and by mass‐analysed ion kinetic energy spectrometry experiments carried out on the molecular ions and major fragment ions. The spectra are characterized by a loss of carbon monoxide from the molecular ion of each compound, a process which is accompanied by migration of the aryl group.
