| Abstract: | The electron impact ionization mass spectra of some pyronylpyrazoles were investigated. The 6-substituted 4-hydroxy-2-pyrone ring in all compounds fragments according to the common mechanisms. The fragmentations of the 3,5-disubstituted N-phenylpyrazole moiety are strongly dependent on the nature and positions of the substituents. |
