From a continued interest in mass spectrometry of heterocyclic compounds 2, 3) the preparation of trifluoromethyl-substituted heterocyclic compounds and determination of their mass spectra were considered. As it is known that trifluoromethylsubstituted benzene compounds eliminate CF2 radical during a series of their electron-impactinduced decompositions, 4) it seemed interesting to see if this behaviour also holds for heterocyclic ...
