The Uses of 1,1,1-TRIFLUORO-5,5-DIMETHYL-2,4-HEXANEDIONE

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.

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.
