An effecient synthetic method for fluorinated tridentate β-aminoenones and tetradentate bis(β-aminoenones) via amination of fluorinated 1,3-diketones with o-phenylenediamine in the presence of trialkyl borates was developed. Ni(II), Cu(II) and Pd(II) complexes with tetradentate bis(β-aminoenones) were obtained. Their gaschromatographic behaviour and main fragmentation paths in the electron ionization mass spectra were described.
