The mass spectra and fragmentation patterns of the title compounds have been studied. The fragmentation behavior and the structure of fragment ion have been examined by means of the MS/MS technique and high resolution mass spectrometer. The successive loss of carbon monoxide unit from the parent ion is typical. The rearrangement of substituted phenyl and bimolecular reaction and hydrogenation have been observed in high temperature.

Key words: PYROLYSIS, MECHANISM, REARRANGEMENT REACTION, HYDROGENATION, CHROMATOGRAPHY-MASS SPECTROGRAPHY
