Abstract Aluminum acetylacetonate, Al(acac)3, was prepared in the reaction between the mineral boehmite, [AlO(OH)]n, and acetylacetone (2,4-pentanedione; Hacac) in water. In this one-step synthesis, the pale yellow crystalline product precipitated out of the solution. Characterization of the recrystallized crystal by mass spectrometry, thermogravimetric/differential thermal analysis (TG/DTA), 1H NMR, and the X-ray diffraction (XRD) was consistent with Al(acac)3. This is the first example of the preparation of the six-coordinate aluminum compound from boehmite.
