The mass spectra of the Schiff base derived from ethylenediamine and trifluoroacetylacetone and its metal complexes

Abstract

The mass spectrum of the Schiff base formed by the condensation of ethylenediamine and trifluoro-acetylacetone shows that the compound is N,N-ethylenebis(1,1,1-trifluoro-4-iminopentan-2-one). The mass spectra of the nickel(II), palladium(II) and copper(II) chelates of the Schiff base confirm this structure for the ligand. Mechanisms are proposed for some of the fragmentation reactions which occur in the mass spectrometer.
