General description
1,1,1-Trifluoro-5,5-dimethyl-2,4-hexanedione (TFDMHD) is a 1,3-diketone. It forms Er(3+) complexes. These complexes shows thermally activated slow relaxation of magnetization under a zero direct-current (DC) field.
Application
1,1,1-Trifluoro-5,5-dimethyl-2,4-hexanedione (TFDMHD) may be used in the synthesis of series of NNO ketoimines bearing trifluoromethyl substituents, via Schiff base condensation. It may be used in the synthesis of octahedral Werner-type cobalt(II) complexes. It was used in the preparation of D2-TFDMHD, by mixing with D2O.
