Thio derivatives of β-diketones and their metal chelates. XIV. Mass spectra of palladium and platinum chelates of some fluorinated Monothio-β-diketones
The mass spectra of the palladium(11) and platinum(11) chelates of the fluorinated monothio-β- diketones, RC(SH)=CHCOCF3 (R = Ph, p-MeC6H4, p-BrC6H4, p-NO2C6H4, 2-thienyl), and of the palladium chelate of CH3C(SH)=CHCOCF3 have been obtained. The platinum chelates give rise to more metal-containing peaks than the palladium chelates. Mechanisms are proposed for the reactions involving the metal-containing fragments. A comparison of the mass spectra of the zinc, nickel, palladium and platinum chelates of these fluorinated monothio-β-diketones reveals that the fragmentation pattern is determined by the metal.
