The massspectrometricfragmentation of 6-(4-chlorophenyl)-N-aryl-4-(trichloromethyl)-4H-1,3,5-oxadiazin-2-amines was studied under fast-atom bombardment (FAB) conditions. To simplify the interpretation of the mass spectra, a number of new 4H-1,3,5-oxadiazine derivatives containing polyisotopic elements (Cl and Br) in the arylamine substituent were synthesized. It was shown that fragmentation occurs
