| Abstract | SummaryElectron impact mass spectra of seven 2,3-dihydro-5-trifluoromethyl/methyl-7-(p-R-phenyl)-1,4-diazepinesR=H, CH3, OCH3, CF3, Cl, Br) have been recorded and are discussed. These systems dissociate by scission of the C2-C3 bond followed by loss of H. to give the [M-H]+ ion as the base peak. The fragmentation behaviour has been investigated using metastable scanning techniques and accurate mass measurements. The origin of some characteristic fragment ions is discussed.ZusammenfassungDie EI-Massenspektren von 7 2,3-Dihydro-5-trifluormethyl/methyl-7-(p-R-phenyl)-1,4-diazepinen (R=CH3, OCH3, CF3, Cl, Br) werden vorgestellt. Diese Verbindungen fragmentieren unter Spaltung der C2-C3-Bindung. Anschließende Abspaltung von H. führt zum Fragment [M-H]+, das als Basispeak auftritt. Das Fragmentierungsverhalten wurde mittels metastabiler Methoden und genauer Massenbestimmungen untersucht. Die Herkunft einiger charakteristischer Fragmentionen wird diskutiert. |
